Hi Guys.... this might not be news but I just tried something today and I was stunned to my bones... I was on the island running some errands and I had no idea how to locate my destinations given that most addresses there are kinda scattered so I brought out my iPhone, launched my google maps and once I clicked on start navigation....... it took me directly to my destination with voice prompt, actual amount of time it will take me to drive there and accurate turning points..... this is so amazing, ya'll should try it and share your views.....


I have no problem going to look for people again henceforth

Been using it for over 7yrs.

I had a few incidents though.
Unfortunately, on this day, I had 2 of my bosses in the car and decided to use the short google route which will save us from a 30min loop. I have been around the area and aware there was another road but never tried until that fateful day. The road was indeed a very good short cut but.was 1qqmissing a bridge. On both sides of the missing bridge was were asphalt road. The saviour was an earth roàd that goes through down the valley to the other side.

Was in Minna 2 days ago looking for NECO office, the search returned exact location but it turn out there were 2 offices, one in town and the HQ out of town on Bida rd. The problem was that my search had every thing but didn't specify the HQ against the state office. I got to the state office before I realized that another office was on the map but couldn't see it from a zoomed screen.

Ikology:
My last take this;

You are not interested in their chemical composition, OEM approvals and API specifications. You are comparing 10W-40 and SAE 40 because they both have same temperature at 100deg when they are yet to be used (fresh oil). Have you considered running a used oil analysis say after 1000km mileage? Your used oil analysis will show the extent of viscosity loss, acid build up, oxidation, sludge formation, wear metals.


you can only achieve 10W-40 formulation with a synthetic base oil, an oil that resists both oxidation and thermal degradation


That you saw them do it doesn't make it right, however the bus model and their lubricant specification/API must also be considered.

Finally ordinally road side base oil without any additives or treatment can even offer some protection, but for how long? Chemical additives helps to extend the useful life of an engine oil.

It's obvious you don't understand my points.

Firstly, I understand what chemical composition is and I understand their effects but in trying to be practical, what chemical composition of engine oil will you see in a data sheet? Why am I discussing data I have not seen. Can you tell me the data chemical composition of say Total 10W40 compared to Total SAE 40? I guess not. So don't blame me if I don't discuss what I don't know.

Secondly, SAE is just one standard, I am also aware of API, ILSAC but in being practical how many people buy engine oils because of their API ratings? If you really want to check all the boxes, even Mobil 1 5W20 may not be used with a Honda for example. It means if you buy Honda you will have to buy Honda motor oil, get Nissan and buy Nissan Motor oil, get Toyota and buy Toyota Motor oil since these manufacturers don't recommend anything that is not in their brand name. They throw you off by telling you about chemical composition and other things like they invented what they are selling and then telling you scary stories of what will happen if you don't do as they say.

Lastly, if boils down to "for how long", what gives me enough protection for long enough and cheap enough is the best deal. Isn't it obvious that the you use an engine oil as long as recommended. From, what I have read, 10w40 should be semi synthetic and SAE40 should be mineral based, do you expect them to be used for the same period? Absolutely not. Our discussion is not about how long but about suitability?

This topic has been extensively discussed on other forums and this picture below speaks volumes.

Note, the temperature on the picture is ambient temperature.

HeavenlyBang:
Feels like this entire post only considers optimal operating conditions.

Fun fact, most wear and tear in an engine occurs at start-up.

Yes so because if you drive a car from Maiduguri-Lagos, you will be driving at operating temperature through out but would have experienced conditions of cold start for just less than 2mins with a thermostat.

Ikology:
OK


Yes they both have the same kinematic viscosity @ 100 deg, however they behaves differently at this temperature. SAE 50 achieved its viscosity (19.6) with just base oil alone, however SAE 20W-50 achieved its viscosity with a base oil and a viscosity index improver chemical additives. Remember viscosity is a measure of fluids resistance to flow and shear. This viscosity index improver additives is a polymeric chemical substance whose molecules tend to stretch out as temperature increases, thereby increasing the fluids internal friction causing the fluid to flow at a slower rate. when the fluid flows at a slower rate, the viscosity increases. The implication is the oil thickens as the temperature increases.

SAE 50, SAE 40 does have Viscosity index improver additives as a component during its formulation.

These chemicals include: Polymethacrylates (PMA), Polyisobutylene (PIB),Olefin Co-polymers(OCP) etc.



Yes winter grades are subjected to cold cranking tests usually at -15deg, this only helps to explain the fluidity or the cranking viscosity at that temperature, The advantage is that oil will not freeze but will remain fluid in order to continue it's lubricant function. it will also paint a picture of cranking viscosity of the oil let say at 25deg. During engine start-up, multi-grade oils reaches its destination faster even in warmer climates.

I wouldn't advise anyone to use SAE 50/40 in any PCM

I have never used either SAE 40 or 50 in my life. However, I have seen an entire fleet of brand new Toyota Hiase buses of an Inter state transport coy use Total Classic SAE 40 in drums as lube oil. This same company buys premium Michelin tires for their use, so its not that they couldn't afford 10W-40.

This thread was created on the day I saw a friend use the same oil and has been using on all his cars for 20yrs now. When he bought the oil, instead on convincing otherwise, I asked myself why not. It's a lesser evil to 20W50?

Seems you care less about start-up wear, high temperature protection and fuel economy(mono-grades are heavier)

Start up wear - I am not convinced because in some places like Alaska, you crank at say -15°c but in Nigeria, I am not sure we get down to 30°C. Yes at 30°C SAE 40 will be thicker and have higher viscosity to 10W40 but the difference is waaaay less than 50%. What is the impact when you still have reasonable flow and that the engine gets to 60 in less that 2minutes with thermostat in place? My guess is insignificant. I think its not as bad as having 20W50 which cars survive on well over 400,000km.

High temperature protection - I don't agree

Monogrades are heavier - I agree 100% due to higher density

Fuel economy - I think it's too little of a difference in density to impact fuel economy

Yes winter grades are subjected to cold cranking tests usually at -15deg,

Not just test, they are graded primarily based on these test. Just as mono grade oil grading is based on viscosity at 40°C and100°C winter grades are graded based on viscosity at -15°c etc their significance deminishes as the engine gets warmer

Ikology:
Multi-grade engine oils are still better in their response to temperature changes. Multi-grade engine oil contains viscosity index improver chemical additives, consequently they have high viscosity index than monograde.
Comparing SAE 50 and SAE 20W-50 whose viscosity index is 95 and 120 respectively (minimum) by Standards Organization of Nigeria (SON) standards or whose kinematic viscosity @ 40 degrees is around 240cSt and 180cSt respectively. [b]The above results implies that SAE 50 has low viscosity index and will be adversely affected by low and high temperature changes. [/b]At a low temperature not necessary less than zero degrees, like cranking the engine, the oil will be thicker and will not circulate faster, leading to wear in some areas in the engine. However SAE 20W-50 with better viscosity index and a lower cranking viscosity during engine start-up or warm up shows faster circulation and better engine protection during cold or warm start of engine.

Secondly is the apparent viscosity at high temperature and high shear rate, When both oils are in service, and the engine is fully operational, the engine temperature has become very high, analyzing the relative thickness of both oils shows that multi-grade will still have a high thickness compared to monograde. The viscosity at high temperature and high share rate at this point in time reveals that multi-grade offers better protection at high temperature than monograde.

I agree with you partly.

Lets go practical.

Taking Kinematic Viscosity @100°C Mobil for instance

SAE 50 - 19.6
20W-50 - 20.5

SAE 40 - 15.5
10W-40 - 15.6

This means at engine operating temperature both SAE 40 or 50 will have nearly the same kiñematic viscosity as 10W-40 or 50.

Ask yourself, what is 10W-40, it is SAE 10W + SAE 40.

What is wrong with SAE 40 or 50 or any monograde oil, their problem is low temperature not high. At higher temperatures, the viscosity is at par.

To buttress the point, look at the graphs for SAE 30 and SAE 5W30 i shared earlier.

You will notice
1. The y axis scale on the left is kinematic Viscosity and it's the same for both graphs but not the same on the right which is density.
2. At 60-100°C both grades look exactly the same but start to defer marginally from 60 downwards. That's where the difference is.

Viscosity index is a relationship between Kinematic Viscosity at 40°C and 100°C. As seen above, what changes the Viscosity index is the Kinematic Viscosity at 40°C while the higher remains the same. Looking into Viscosity index in this case will not be a clear picture of the relationship between mono and multi grade oils.

SAE 50 is indeed 20W50 at 100°C but not the same at 40°C.

The point of this thread is to explore the fact that at 100°C a Winter graded oil isn't necessary. The question is at what low temperature is the winter grade absolutely necessary, I think 40°C is still not it. Meanwhile cold cranking values of viscosity of winter oils are meant for sub zero temperatures.

In other words, what's the harm in using a monograde in place of multigrade when in the first place most people use 20W50 in place of 5W20 for example. SAE 40 seems to me a lesser evil than 20W50 as substitute for 5W20.

So?

replete:
Temperature in Jos in some early mornings varies from 14°c to 17°c how about that? Wud you still recommend a 20w on especially a 2010 model car?

Look at the graph again and imagine what winter temperatures are like. We are talking about temperatures below zero here.

Look at this and tell me which one of the
Winters fits our temperatures, is it -10°C?

homeboy205:
Nice perspective

But we still get cold in 9ja, and I’d prefer we stick to factory spec

*****I support the motion of factory recommended oil*** And I respect your point of view too

I read some where that when the new multigrade oil was created, it was initially called all season engine oil.

Understand this, there are all season tires but there are mud, snow, desert, off-road, ràcing, drifting etc tires. Basically, àll season tires are good for all season but not best for all terrains.

Same with the engine oil, manufacturers are aware users prefer all season oil so they gave them that but there is engine oil for every engine and for different seasons and even better performance and higher mileage.

So àll season engine oil is good for all seasons but too expensive if you have just one season in our case.

Getting it right seems to be our local issue. The challenge ranges from supply, price, quality and even the knowledge.

A lot of drivers don't know what oil to use and even when to change it. My concern here is the engine oil spec.

The average US cars we import have a recommendation of 5w-20, 5w-30, 0w-20, 0w-30. The most common oil in Nigeria is 20w-50 followed at a distance by 10w-40.

Lets break the oil spec down one more time.

These are multigraded oils, meaning it is one grade of oil at one temperature and another grade at another temperature. It basically has a wide temperature tolerance.

Before going further, a monograde oil such as SAE 50 becomes too thin at temperatures well greater than 100°C and will be thicker at temperatures well less than 100°C. The main issue is flow and lubrication. At temperatures say 0°C, an SAE 50 will not flow well and thereby the engine with such oil is operating technically without lubrication which is disastrous.

This gave birth to multi grade oil that will flow and lubricate at 0°C as well as at 100°C and still maintain the specific viscosity it is meant to.

Meanwhile let's keep in mind that most engines operate at an optimum operating temperature of 90-100°C.

Lets use 20W-50 for example

20W - the W is "Winter" graded at SAE 20 winter
50 - means the SAE 50 grade

The SAE grades we have are 0W, 5W, 10W, 15W, 20W, 25W, 20, 30, 40, 50 and 60 for engine oils.

Now to the crux of the topic, all Winter grades are specifically engineered for cold cranking and starting which are relevant for sub zero temperatures.

The practice of constantly recommending a multigrade oil when we can equally use a cheaper monograde oil in our climate arises. Why use 5W-20 when the 5W isn't relevant to our climate. We could be using SAE 20, SAE 30, SAE 40 and SAE 50 instead of the more expensive multigrade versions.

I saw someone using Total Classic SAE40 for a 2010 car and I couldn't talk since it actually doesn't make sense to use 10W-40 in a climate that will hardly get down to 10°C.

See the graphs for 0W-30 vs SAE 30

The real major difference starts at less than 30°C. I have done live scan in several seasons and have never seen even coolant level at 30°C.

It is safe to conclude we don't have winter and we don't require multigrade oils.

My thoughts actually.

Either low brake fluid or rear brake light

This thread is created to dispute or correct the wrong impressions with regards to healthy foods.

I would like us to make contributions to unconfuse the minds of those who have been misled like in the following narrative.

I have this close friend whose late mother died of a diabetes complication. The issue here is that he has developed a strong will to prevent him self from diabetes by regulating his food.

As a result, he has prohibited him self from certain foods especially carbohydrate rich foods such as pounded yam, Akpu, ggarrri, Amala, Semolina, spaghetti, noodles, sugar and sugary drinks etc.

Basically anything carbohydrate and sugar is considered taboo by this guy which I tried to unconfuse his mind. Rather unfortunately is the fact that his meals which he considers carbohydrate (sugar) free are foods like wheat meal, unripe plantain, beans (cow pea), water yam etc

We had this argument which I googled nutritional value, he didn't like what the search proofed and decided to call the research lies and fake.

I asked him why he eats wheat meal and not Semolina when both are made of the same thing, wheat. I also told him the major difference between yam and water yam is the higher percentage of water in water yam hence the name. I told him the beans he has so much regard for has more of carbohydrates than protein.

This guy lived years based on lies, misconceptions and misleading information..

He also believes that not eating sugars or carbs will prevent him from diabetes, I told him it's not true. I told him no one knows what causes diabetes especially type 1.

I also have another friend who prefers cow intestine to the flesh calling it red meat which is bad. I had to tell him the red meat is more important having higher protein and less fat than intestine which has higher fat and lower protein.

The different types of recommendations my parents bring home is a thing of concern. From a leaf that lowers blood pressure but will keep them awake peeing to a N10,000 dose of herbs that will work for all illness but with a side effect of 3 days diarrhea.

I will start by posting nutritional values of some common foods.

Thanks sis. Seriously I'm depressed and I don't want them to see me as a bad person. Have been going round to see if I can raise something and take it to the management direct

Get a statement of account which will show how the money wasn't used by you and it's unavailable at the moment due to the negative credit you had.

Go to the accountant with the bank statement and keep a photocopy to explain things and ask for a payback plan since you don't have the cash.

Really, I thought it's the sun that moves around the earth; it rises in the east, moves across the sky then sets in the west. If the earth is really rotating, we should feel or sense it somehow!

It's the moon that revolves around the earth while the earth revolves around the sun.

The rotation is really slow but to explain further, if you are in a slow moving car, you can't feel the speed. Once the speeds gets to 120km/h you feel the speed, by the time it gets to around 300km/h you definitely feel G-Force acting on you like when a plane is taking off.

Pls help me people. My world is collapsing. It's a marriage of 10years and blessed with 3kids (2 boys and a girl). Like every other marriages, we've had our own shares of ups and downs. No marriage is perfect.

Last month i went to work. By the time I came back the children were no where to be found, including my husband. Initially, I thought they went out or something. Around 11pm I got worried and called my brother in-law who is a police to track my husband numbers

He contacted other family members and he found out my husband left for UK with our children forever.

I don't know what to do. I'm running mad. Pls is there any authority I can contact in the UK? Or can I go to the UK/ British Commission in Nigeria to lay a formal complaint? Is there any NGO I can contact?


Modified For those saying I'm a bad wife, I'm not. I've been very supportive in a every way a wife can be. I've lived in both physical and verbal abusive marriage within the last 10years of my life. He's a violent man, adulterous, alcoholic and a fervent smoker. He gets drunk and get home and beat me up Infront of the children unprovoked. I have evidences and witnesses

I often threaten him I would take my children and go away cause I can't watch and allow them to grow in such a toxic home.

So sorry madam.

Please first do a self check and point to yourself your own faults, if possible seek advice from someone who will tell you what bad things you did to deserve such treatment.

Secondly, your husband was wrong I admit. You don't want to make more of a mess than it is already. Be bold and get your husband to the dialogue table.

Thirdly, your first priority at this time should be their welfare, then find out his plan for the kids and how you can come into the plan. Finally, ask him to make things right by either saving what is left of the marriage or divorce.

At this point, hold off any court, human rights, NGO, embassy or police case till you can't get his family to get him to talk. Give the family a dateline when you will report to relevant agencies.

tidalstorm:
I smell sarcasm.
It still shows one thing though, the marriage had been over for a long time.
The kind of marriage where the couples sleep back to back and give each othher the silent treatment.

The guy just took ghosting to a whole new level.

True talk, the marriage was over long before he got papers for him and the kids.

Whatever the case may be, that a well laid plan was executed so well means op has been living a lie for a long time while being oblivious of her real problems.

Despite op's faults, the hubby is clearly a weak and bad man. Some how I feel he orchestrated the plan in part to punish and frustrate his wife and not for good intentions for the kids.

His actions is completely out of order, he can be sued or deported for this. It is abduction which ever way it looks.

What happens to divorce? He had the option of doing it legally but didn't which means he is not doing it for best intentions.

I think if he went to court with clean hands, he can get the kids with plans to give them a good life abroad.

There is nothing in eating together.

Let them live together and I will agree some progress is made.

Kaduna city is highly segregated into religious lines. Eating together won't undo that. As soon as they finished eating and posing for photographs, the Muslims will go to Kaduna North while the Christians will go to Kaduna South on the other side of River Kaduna.

They only reason is Greed NY the operators.

There used to be fuel scarcity every Christmas, it was greed by oil.marketers.

Rice is what it is because of greed. There is absolutely no reason rice should be expensive even after the border closure but the price of local rice is over twice what it was before the ban.

Cement at the factory is still the same price it was but the retail price has gone up by more than a thousand Naira for no certain reason other than greed.

For onions, the same greed has been in play.

The same can be said of the black market FX exchange rate.

All these consumables experienced a little shortage but economics of demand and supply doesn't work in Nigeria.

Greed makes economistsq look like fools.

I need something that is strong, durable, reliable, cheap/easy to maintain, with best comfort & enjoyment at that level.

I'm considering the following.
1.Toyota corolla 2003/04 Bank edition
2. Honda civic 2007/08
3. Volkswagen jetta 2006-2008

My only advice is remove the VW Jetta from your mind and list. That car is a serious liability

Claudiusdeux:
Thanks for calling me a kid

I wonder who is the childish one among us, someone who responds to a comment with abuse, or someone who makes his comment and goes.

Anyway, thanks again for abusing me. I'm much obliged to you

Read my comment again, I was talking to you.

My first line was, "every comment above yours". Those are the kids. I meant the first sensible post on the thread is yours so I agree with you.

Sorry if you felt differently.

Claudiusdeux:
For once I agree with Bubu...

The problem with our borders is that they were arbitrary lines drawn in the sand at the Berlin confence of 1885, by colonilaisits , most of whom did not know the land they were carving up...and subsequently people were just split into groupings they knew nothing about.

When the OAU came along, they signed a pact to 'respect the borders'...so the colonial borders became reality.

But let's be honest, they are still lines on the ground. What Buhari said can be said for most African borders....excepting probably South Africa...which has something of a fence so to speak

And while what he said is wrong....adequately fencing and improving security along our borders is going to cost a lot of money

(P.S This comment does not mean I approve of the insecurity of our borders, and the insincerity of our government in dealing with the insecurity. The problem is, the basis of the borders themselves get k-leg. The OAU knew this in 1963, but since the alternative was crisis ....they kept the old borders)

Every comment above yours is clearly out of touch with reality.

Nairaland is full of kids who cannot understand very simple things about governance.

Poliçing borders is a problem but poliçing Nigerians is a bigger problem. Buhari knows it, I know it but majority do not understand how difficult it is.

driving:
I wanted to change my front shocks last month. The mechanic said I could repair it if I don't have money for a tokunbo. Though I later bought a tokunbo. Has anyone done this before? I mean the repair. How long did the repaired shocks last if yes?

Yes I did, Mazda. It worked like magic.

The valve inside was found to have broken into pieces nd changed. I used it for 3 months before I sold the car but the fix was totally worth it.

A lot of so called toks had the same repairs.

HigherEd:
Where you see six months

First of. Many graduates of Covenant University have gone on to far higher ranked universities, even ivy leagues and I haven't heard anyone complain about dated transcripts.

Transcript is just an academic record. The certificate carries the date. She should have requested both at the same time to avoid nonsensical delays.

I graduated in 2015 and I have gone to collect my certificate in 2016 when the University reminded us to come and collect it. How can you graduate in 2013 and be looking for who to tension in 2020.

When I requested my transcript from Covenant to a university in Canada, it took less than a week to get there. It happened same as hers.

Study the timeline again.
Covenant responded and acted within 1 or 2 days anytime she supplies the required document.

Now again, if she wanted to call them out all she needed to do was send a message in the closed social media group first, where all officials responsible are also present and get speedy response.

Abeg na she know.

My only question to CU is why the maiden name issues?

That is not theirs to rectify.

Her maiden name is a name she took before or after issuance of certificate and we all know it cannot be changed, in the case I guess after issuance of the certificate. So any confusion on the changed name is her and the Law school.
