u go like quarrel pass fight oo

Kingdemu:
Nawao... How I come tek be the OP again? Well, make una settle una issue I don commot for here.

na because you dey elastic na lol

erico2k2:

Seriously, Ok what chart are you talking about? meanwhile howcome we drive the same car in Poland and same car in Nigeria and the same Oil specification is required for car lub? My RRS is 5W30, the same with my Guy in Russia which is meant to be colder? If you do not know the meaning of Elacticity and think it is limited to elastic as per rubber then you have no busniness arguing in anything to do with tech!

the chart am talking about is the ambient temperature table diagram chart that show -13 <-------------5w30-------->+38

the only thing I have learned from you is that oil is elactic after some research base on its process of changing viscosity

erico2k2:

Bro no offence,I cant drive a peugeot of any model!me preference! talk BMW, Audis and |Range rovers, we are game!

bo bo juice , see as u dey call big big motor name ,na the Peugeot them use give you example of car with oil temperature gauge , ok for me to believe u send me 2007 range front bumper to PH

erico2k2:

The joke is on you mate who claims there is summer in NIGERIA!
9ja has Raining(Wet) and the Dry season, I dont know where you get this your wanna be abroad mentality of Summer from, The west have Summer/Winter/Autom, so you my friend must be extreemly Ignorant! the average temp in 9ja at its lowest is like 20, which is summer for us!

SerikinGamo:


I live in Nigeria and there's nothing like summer here

some just come here without contributing any meaningful thing , na summer be the question? abi dem no get car ? abeg what is summer max temperature ?

heykims:
Thanks so much for the enlightenment guys.
So judging from ur analysis, what oil specification would u recommend for a Toyota camry 2005 being used in Lagos?
Mind u, I presently have 20w50 there (synthetic), the dealer used that to service it as the car recently arrived. Guys on nairaland have scared the hell out of me telling to go drain or and use the 5w30 recommended which I planned doing in few weeks time until I came across this thread.
I also crave for good fuel economy.
Moreso, what does APL, XHP, GSX etc mean and which one will be most suitable for my car?

0) check your car engine oil chart diagram for recommendation of different hot ambient temp , or CONPACTABlE with Lagos temp
1) 20w50 SYNTHETIC is not wrong and will flow better than 20w50 MINERAL oil, giving you some percentage of fuel economy too plus good protection
2) depending on your usage and state temp ,30w for +38 and below , 40w may protect all the way up to +48 to +50degr and have more fuel economy than 50w but will never damage your engine
3)you may start checking your ( mpg ) to know your fuel usage and a ( UOI ) to know engine wear , tear ,or Shear ratio with 20w50 synthetic compared to the 5w30 you may use later
but I bet it only fuel economy u may observe and higher wear with 30w in hot temp above +38 degree

also note that there are many factors that improve fuel economy
1)u most use a themostat to regulates proper engine temp, without the fans running continuesly like many owners do and set up by default to run at 100degr only , it also helps the engine oil to reach operating temp quickly
2) the coolant temperature sensor must perform properly, so it can send signal to the ECU (car computer) that engine temperature is optimal for better performance
3) the O2 sensor must be performing properly to send signal to the ECU about the already burnt fuel and air ratio so that the injectors can limit it's fuel supply for CLOSE LOOP operation, note if coolant temperature sensor read lower temperature always the engine will continuesly running in OPEN LOOP operation and consume more fuel
4) weel aliment and tier air pressure etc.
5) driving habits ,loads etc.

theoilguy:


Scammer mechanic, where is my money? Anybody who transacts with you is at risk... Everyone beware.. this guy is a thief

lol , e be like say you follow those people weh de send money for poeple account ,to get the USA magic oil 5w30, hahaha without knowing the otenticity

EngRichie:
Scientifically, there is element of truth in your submission.
Viscousity is one of the properties needed for better protection. Also, any oil will thin out more under higher conditions of temperature, load and shear stress but the synthetic oils thin out more slowly.

However, recent advancements have allowed the use of lower viscousity oils while still offering good protection.

Sometimes, when we consider viscousity, there is compromise between best protection and best fuel economy and this is where some manufacturers are silent and users are innocent.
In some vehicles, it is not out of place to upgrade to next higher viscousity grade because of high temperature, high speed and high load driving. In some other cars, it is okay to stick with manufacturer recommendation because of the engine's design and a good controlled cooling system.

I thought I was the only one that has this ideology , thanks , so the answer should be that it varies by types or brand of engines base on manufacturers recommendation maybe oil QUALITY
I PREFER BETTER PROTECTION ( A LITTLE THICK OIL 40W IN HOT AMBIENT) THAN FUEL ECONOMY 30W
REMEMBER oil loss it viscosity after a while

Kingdemu:
Pardon me but it appears you are new to Car Talk hence don't know who erico2k2 is when talking cars, right? Cos I don't think he should be among people to be "shamed" for not having a feel of what a modern car is.

pardoned ,and yes I maybe new to car talks but may know more than most unreliable so called expects here , erico2k2 is nothing but a joke and an online bully who KNOW LESS HOW CAR WORKS and derived joy from shaming naira-landers in several trends as a pro and should be shamed randomly too when found wrong, how can a pro not know that engine oil temp really exist and is installed in cars he stated above that doesn't have it , what has he contributed in this trend except from trying tell that don't know what am talking about and inferior propaganda

erico2k2:
the short answer to it question is NO it doesn't matter. All fluid has elasticity. ie range of hot and cold tolerance. then the weight.Oil are more effective at max engine temp.

1)short answer to it question is NO it doesn't matter (question = ) why would it not matter when engine manufacturer oil chart say other wise
2) All fluid has elasticity ( answ =) no, oil is not ruber and can not be elastic , car fluids has no elasticity rather they have viscositys or viscosity improvers
3)Oil are more effective at max engine temp (question =) engine and oil temp is 100 degree ,(1) what max temperature range can 30w viscosity oil accommodate above 100degr ? (2) what viscosity will 30w be above it's normal operating Temp , up to 108 degr instead of 100degr

erico2k2:

you mean this
I have not own this b4

you may consider having one so you can participate in trends like this, which you do not have any clue about

erico2k2:

you dey live for the wrong part, where that guy dey live Summer dey

you are nothing but a joke, pls tell us what we have here

erico2k2:

ok you are very correct non of the cars I ha e driven or ow ed has an Engine oil temp gauge gear oil yes in case of my jeep.so frm Vws to Audis.to Mercedes and Bmws and Land rovers oh and Peugeot. erm Rover and Honda's. I ain't seen it so what car has one.I would like to increase my knowledge.cos 50% of 9ja fry thier engines with wrong oils.

am happy you want to increase your knowledge , now we can talk reasonably

Kingdemu:
One of my cars has one. It's a Peugeot 206cc

@eriko do you now believe there's car oil temperature gauge and you know less about cars and need to explore more than forming I too know , when you know less

@kingdemu , what is your car oil temperature during hot summer ambient?

erico2k2:

Nop I cant be polite cos it's advice like these that lead people to kill thier cars. There are cars equipped with double cells and double fans.leave the damn car the way it was manufactured. No one in the US will advise you to do same in summer cos wen U say summer you mean America or Europe cos 9ja do t have it.I repeat Texas is very hot in the summer and Florida has a topical feel no one does that shyte in thier cars. replace like 4 like parts. you belong to them school of thought who sing tropicalization.

1) there was no advise (because he already has a two cell radiator )
2) all what your writing has nothing to counter with what I wrote above
3) you said =wen U say summer you mean America or Europe cos 9ja do t have it { chia tell me if we have winter or freezing snow, defind summer }
your comments are ABSOLUTE and UNRELIABLE

erico2k2:
finally OP you have no clue and U need to read more on Engine oils relative to car brands.

FINALLY is likely you have not come across a car with engine oil temperature dashboard gauge, that show the temperature of a car engine oil temperature, which means you have no clue and need to read more on engine oil relatively to car brand
and your advice maybe ABSOLUTE or UNRECOMMENDED

erico2k2:
OP did you say Engine oil temp gauge??

capital YES
or have not come across a car with engine oil temperature dashboard gauge, that show the temperature of a car engine oil temperature ?

erico2k2:

Dead advice.leave the damn thing the way it was manufactured. Frisco is hotter than the Sahara during summer. we should stop this africa is hot mentality.

what is Dead about this issue ( don't you have a better polite way to express yourself? ) or what wrong advise are you talking about when I said NO when asked if one cell radiator is the issue (after he admits he has two cell already )

two cells radiator is bigger and contain more coolant and have better chance to discharge heat especially during a hot summer traffic jams with air conditioner on ( don't it make sense to you, Mr perfect ? )

you sound un-polite without reading properly which is very bad of you
#be social

Kingdemu:
Does it come with warranty?

is it used to detect leaks, stop leaks or both? am having issues with leaking ac gas (two day leak after refill ) , have been tracing it with two unsuccessful attempts by two unreliable ac guys , bought another compressor and condenser but no success

I need a leak detector

I am here to learn and to share my thoughts and experience

many in various trends are saying our ambient +43 degree temps don't matter and have no effect on oil, that car with radiator regulates engine temperature and also help to bring the engine oil up to operating Temp 100 degree through the help of the themostat , asking if our weather is hotter than engine temperature 100deg

there's is also a clear statement by oil manufacturer saying in 5w30 , 5w is the low temperature weight while 30w is the oil weight in 100 degree , which is also the engine coolant temp range,

on different occasions during summer , you find out that oil temperature gauge move above 100 degree , (which they claim the oil get to 30w at operating Temp) to +44 ,+46 and above .

my question is....

1)what viscosity will 30w oil be in 106 degree engine oil temperature during summer ? ( = it will be lower than 30w VISCOSITY which will not lubricate the engine properly and course more wear and tear).

2) why does engine manufacturer display ambient temperature oil chart which shows that 30w arrows to +38 degree and BELOW , when they know that it is suitable for ALL temperature?

with the above ideology I wish to prove to you that 40w mostly or 50w oils may be the best choice for +44 or higher temperature and severe load condition, and will not harm our engine, (and 30w is for state's with +38 and below temperature ) the only disadvantage is less fuel economy , but with synthetic, flow will be better.

pls guys what is your engine oil temperature gauge reading during hot summer?

what your take in my view?

REMEMBER TIME NA MONEY

feelme3:


Na the issue be that. The other guy is insisting that it be poured to the Max line in the reservoir tank without dilution (also says DON'T DILUTE on the can). My mechanic says it's poured straight into the radiator with the water. That's why it's radiator coolant. I no know again

use it to fill the radiator before filling the radiator reservoir ,but do not dilute it, because is already mixed with distilled water

Omotakins:

Thanks. It is a two-fan radiator. Can the problem be the fact that it is a one-cell radiator?

NO , but two cells help more in hot summer traffic jams

sooperrescue:
5w30 API Sl engine oil for Toyota ended for the model of 2007/8 and from there. they recommended 5w20 or 0w20. Honda has been using 5w20 longer before Toyota did. Our number one problem here is the use of substandard engine oils on our vehicles. Mineral oil does not cause sludge if regularly serviced but there are a lot of negative effects associated with the engine oil being used by ignoring the advice of the manufacturer. The outside temperature does not determine the type of oil a car should use but the oil is factored to the design of the engine. Until recently, all 20w50 oils were API Sl until Mobil introduced xhp API SN. Cepsa was being adulterated because it was an API SN and an 20w50. All cars being used in Nigeria will surely be destroyed by the manner of usage but the time of its destruction lies in the owner's negligence or ability to maintain it.

ironheart:
About this oil matter, all the oil recommend are correct includding the 20w50. All we need do is to do some research. I have been busy checking user manual of most vehicles. Now they have a chart for anticipated ambient temperature.. using 20w50 in modern cars is correct. Mostly in areas where the temperature is very high.


10 or 5w30 is like the average between the high side and the low side.

For recommended oil viscosities, refer to the chart. 10W-30 grade oils are not recommended for sustained high speed driving.



What i mean is. In US n Canada where most of our cars come from, the manufacturer has to recommend an oil that can protect the engine from below freezing 0'C to 40'C ambient temperature. This is because it is not practical to change oil every time you driving between two regions of low temperature and higher temperature levels.


Here in Nigeria except you driving to some norther states during the harmattan period, where temperature can be as low as 12'C. You are safer running those cars with 20w50. As a matter of fact, if you run inter states, 20w50 is better cos of the high rev, high operating temperature and long distance.


The down side of 20w50 is in low fuel economy which may be put as 5 to 13% loss

my brother may God bless you for understanding this simple chart diagram you presented

your mama school fee no lost at all

make una leave wetin them write for motor enter motor jor

the worse be say ,them say e too thick e go condem your engine , chai where oyebo write that kind thing foro manual , except u use thick one for Cold weather, na raining season we get for 9ja na +20 lowest

where we should concentrate our enlightenment is ,
1) making sure engine and oil reach operating Temp by using themostat( or without themostat but don't allow your fan to blow continuesly, by disconnecting the factory, so fan work with coolant temperature sensor settings, so that oil can reach operating Temp on the long run to remove moisture ect )

2) API rating sj , sl , sm , sn etc

3) oil change intervals ( 3k mile for minerals oils , 5k for SEMI SYNTHETIC , 7k for synthetic ) which 80% of mechanics and Nigerian owners don't know really excit , including my mechanic ,he dont even know what OBD or check engine means

4) checking oil level always

remember time na money

NobleEngineer:


my naija ppu, our defender don finally show!!! now we can continue using our 20w50 in peace.... ahahhaahh

try use correct API rating oo especially semi or synthetic one for better FLOW

if you leave below +38 degree try use 10w30 ,you go gain better MPG (fuel economy), but u see 20w50 no go ever spoil your car engine , except say na fake oil u use, no buy for road again

the only better things be say 5w30 dey always come for synthetic and e dey stable well well

remember time na money

radautoworks:


Hmmm... But they use manufacturer spec 5w30 for "cold weather" in the middle east and don't change engine upandan like in Nigeria. What do I know, maybe their car God is mightier than our own.

Let me just drop this here because me I don't know how to type repete https://www.bobistheoilguy.com/motor-oil-101/

https://www.aa1car.com/library/motor_oil_605.htm

1) look closely the chart you posted is not in degree Celsius °C , it is in degrees Fahrenheit °F ,100 °F degrees Fahrenheit is equivalent to +38 °c degree Celsius simple , check other charts in this trend with Celsius and Fahrenheit to compare ,and post it for me my phone has issues to upload pictures

2) most of them don't believe in God, they mostly believe in science and science says use your car manufacturer oil chart ,and the chart say 20w lowest range is -7 and 9ja has +22 minimum temp , u see the distance , the reasons for lower viscosity oil is because 90% of engine wear is at startup , infact we don't have cold start in 9ja

3)you may use sj 5w30 at +38 degree or lower not higher temp , using 5w30 at +45 may work but will increase wear and tear in your engine , I didn't know if newer oils can withstand higher temp but sj 5w30 can not according to the chart

4) any comments?

can someone help me with Camry oil chart diagram

remember time na money

radautoworks:


I am still waiting for the answer whether Nigeria is hotter than the middle east where they use the said oils.

1)look at charts closely, it says 5w30 is best for Cold weather, do we have cold weather?=NO
2) look at the OIL ambient temperature diagram chart closely and prove me wrong, it shows that 5w30 API sj maximum temperature operating level is +38 not +45 or higher

did Toyota ever tell you that 5w30 API sn or newer can withstand +45 degree or higher (instead of+38 degree for sj?=no my dear

think harder Toyota never suggested one particular viscosity for thier car , if na lie ask gov nwike lol

It makes it easier once you understand you can't save every man in some situations.

The best you can do is advise your loved ones, people you care about or someone that really cares for his/her wellbeing to avoid buying Nigerian used vehicles, if he/she can afford to financially.

u see i have learned a lot from you about cars WITHOUT you knowing but u see this issue about viscositys that a car manufacturer state clearly in their chart and even wrote that thick helps to lubricate engine properly in hotter climate or severe condition but unsuitable for lower temp which we don't have , I didn't concor
