I have come realize that conventional oils come in different weights like 5w-20 0w-20 etc. These oils are not synthetic.So is it compulsory to use only synthetic oil for oil change. or can these conventional oils be used too? From gazzuzz and the likes, it is as if one must use only synthetic oils for oil change.
Can someone shed more light on this.

gazzuzz no more Mobil 1 0w20 oo na mobil 0w-16,

now it 10000 miles or one year.

Toyota introduced the A25A-FKS or 2.5 D-4S engine in 2016 like the first member of its new engine family “Dynamic Force Engines”. It is a 2.5-liter inline four-cylinder gasoline engine combined the newest Toyota’s internal-combustion technologies which can be found separately in previous engines produced in the last years.

The A25A engine has a new open-deck aluminum alloy cylinder block with sleeves cast directly in block material. The longitudinal axis of the crankshaft has a 10 mm offset against the axes of the cylinders. The crankshaft has 7 traditional counterweights and one with tooth gear. That gear on the crankshaft drives the balancing unit attached to the engine block at the bottom. The engine got the high-strength connecting rods and lightweight aluminum T-shape pistons with a special resin coating. The upper compression and oil rings have a DLC coating (Diamond Like Carbon). The pistons are cooled with engine oil sprayed by two oil jets for each piston. The oil system was also upgraded. The main innovation is the second generation variable-pressure oil pump controlled by ECM electronics.

The engine has an aluminum 16-valve cylinder head with two chain-driven camshafts in separate casing at the top. The angle between the intake and exhaust valve is 41 deg. The intake port has a laser-cladded valve seat while the exhaust has a normal pressed valve seat. The valves are actuated by camshafts via roller rocker arms. The engine is equipped with hydraulic tappets for continues zero valve clearance. The intake and exhaust camshafts are driven by low-friction single-row timing chain with a pitch of 8.0 mm. The A25A-FKS features the Dual Variable Valve Timing system (DVVT). The electric actuator (VVT-iE) is used for the intake camshaft; the traditional hydraulic VVT actuator was attached to the exhaust camshaft. The exhaust camshaft has an additional cam for the high-pressure fuel pump. The head cover is made from polymer material.

The A25A engine has a combined fuel injection – in the combustion chambers (direct) and in the intake ports (multipoint). That Toyota’s system is named as D-4S. Each high-pressure fuel nozzle for direct injection has six holes and spray fuel at mid and high engine loads. The low-pressure nozzles in ports have 10 holes. The multipoint fuel injection operates at low speeds and at mid-range together with direct injection. The fuel pressure in the system is a range of 2.4-20 MPa.

The engine has a simple fixed-geometry plastic intake manifold and electronically controlled throttle body - ETCS-i. There is no restricted air in the intake manifold, in that reason the engine was equipped with a vacuum pump driven by exhaust camshaft to create enough vacuum in a brake booster. From the exhaust side, there is a stainless steel exhaust manifold (header) with integrated catalyst converter and EGR pipe.

The modern environmental rules forced the big changes in the engine cooling system of the engines. The 2.5 D-4S engine has an electric motor-driven water pump, electronically controlled thermostat, and shut-off valves. The new system contributes to faster warm up and optimal cooling on all loads range.

In the result, the new 2.5-liter power plant is the most technologically advanced engine ever produced by Toyota. The maximum thermal efficiency achieved the line of 40% - one of the world's best results for a conventional engine. Now, when the A25A-FKS moved the output and fuel economy on the next level, the 2AR became the past.

But you were blind to her tweets complaining about access bank too.

radautoworks:
You do know we'd have charged you the same price and you'd have had a warranty right? Diagnosis 2.5k or free with repair and shocks labor about 7.5-10k lol.

One, You are too far for me. And you cant collect 10k for fixing 4 shocks and bushings and linkage.

GAZZUZZ:
It's in the workings, they are just waiting for election to be over

Also in the workings is electricity price increase.

Kashif:
A mug of draught Heineken will not sell at the same price as a mug of same Heineken poured from a bottle.

I am sure we know the difference. Let us not even compare that with say, Hero beer. No disrespect!

The same part will cost differently from seller to seller, depending on seller's supplier, overhead, brand, marketing skill, etc. If you now throw variety into the mix, a lot come into play. The same applies to labour. The important thing is quality, and standing by it! How many tree shed guys will refund your money if they are wrong without law enforcement guys' involvement?

A bottle of Hennessy XO will buy a carton of Hennessy VS and still have some balance. If you don't know the difference, you will call the XO seller a thief!

If your sell genuine Mobil 1 for 20k based on all the factors above. And another seller sells for 17k and are both genuine. The 17k guy will have more patronage. Prevailing market prices should also play a part.

asamwababy:
There are car ownership schemes abroad and only few will pay outrightly for a car.

I used to be a loan shark and you see bankers on 100k a month buying a 2008 camry so what re you talking about.

If the British and Americans were buying cars they could not maintain would their be anything called Tokunbo vehicles.

How many tokunbo vehicles have been exported from Nigeria?

Sensible conversations this 2019 with no sentiments.

Car maintenance has never been cheap and no miracle with make it cheap except patronising kazeems.

Stop complaining about what the mechanics charge its a matter of choice,some Nigerians have no business owning cars simple.

Even the abroad you are shouting lots or people run away from dealership because they believe they are rip offs. Thats why there are lots of DIY videos online
People change Shocks DIY oil change is even very common.

You cant stop people from complaining because you feel its right to charge high. Even though I agree with that fact that Nigerians buy what they cant maintain.

This is why is support fuel subsidy removal. By the time you buy a litre at N250 you will buy smartforwo or Suzuki alto.

This things work well.

Some few months ago I wanted to overhaul my suspension. From gazzuzz posts I know he charges 10k suspension diagnosis. And 15k or more for suspension installation.
I called a kazeem he removed my tires and wrote all I needed to buy. I bought original shocks bushings linkage etc.
I watched YouTube on suspension diagnosis and complication that may arise from installation and how to prevent them.

The kazeem Installed all of them and I paid him 10K.

I didn't allow him do a shoddy job. Infact the guy tire for me.

Truth is for less technical jobs you can use your kazeem. But for more complicated jobs. Na dem we go dey rush.

More than 6 months now no phiim.

Negotiable percentage. But not more than 20%.

Aunty How much do you replace shocks. Based on your hourly basis .

Truth is we are used to kaseem whom we can negotiate and price down. We know dealership like elizade they are expensive so dont go there. All these in between dey cause confusion. You no be kazeem you nor be dealership, then who you be. Elizade go charge me 10k for scanning. Gazzuzz go charge me 10k for scanning too. Elizade get big scanner gazzuzz dem say he get small scanner. So we are confused. Where to categorise unna

nurey:
So you don turn magician. I am not talking about DIY too.

Your theory makes sense for some aspect of engineering but not all.

it has worked for me alot.

nurey:
Haaaaa, I used to think like this before everything dey Google just watch the video and read.

Even me sef know there are somethings only meant for professionals, you need to be taught and showed not reading or watching video.

In any line of work where people get trained to fix you don't just watch videos and get a hanG of it, only very few humans are born with such talent, when I was young don't ever fix something in front of me cause I would catch on and do it next time, I just need to watch and I will catch on, but as am growing up I am losing the ability.

Well it's your car so you can do as you like, I remember QG15DE ordinary timing chain show mechanic watch video, the man don use 20 years on the job nah oga pata pata, still he no fit set timing chain if you want the complete story buy me a drink and I spill it

if you read very well you see i was talk about turning your kazeem to gazzuzz not DYI

What small car with the best fuel economy would you recommend.

antagonist:
let me not even say what I know about this jarkbauer handle for now, i will keep it for a good day, that fateful day tables will shake and break and the gods will weep

Una sha like to change topic

DelTel:
You get time sha.

Silence often always golden, face your work.

Or are you a NL staff/MOD ni.

gazzuzz is a moderator here. it is only a moderator that can PM you direct message without that generic NL message.

seanfer:
OP it’s a pity that People like you always think they’re the only ones that must be right.... From your write-up nothing here shows Gazzuzz rip you off, It’s where one work He chop and that’s why it’s called workshop.... If Nigeria is a western Country where People are trace with their social Media, I’m sure Gazzuzz would sue you to the last kobo you will make in 10 yeas time for defamation of Character... You work and you pray to make gain...

even though i dont agree with op but believing and saying someone is overpriced is not defamation of character

Giving birth through CS in Lagoon hospital i heard is 850k while in Sanwoolu Clinic Haruna street is 150k... Ha!!! Lagoon na scammer.

GAZZUZZ:
you bought stolen parts.

You are ignored.

I dont know who is more petty between you and 50 cents

franksam2009:
your friend won't have gotten these problems if he had used the specified oil, coolant, transmission oil for his car

Hasty generalisations
He uses 0w-20 mobil1.

I dont know how oil is related to kick starter compressor and alternator. Even the steering rack.

coalcoal1:
did he buy a flooded vehicle?

Nope. He bought it of someone he knows. Carfax was very ok

Is it true that some devilish house can cause your car parts to spoil mysteriously.?

I have a friend that drives a 2013 Camry. He imported this car himself car was sound when he brought it to Nigeria 9months ago. He has changed oil pump.alternator compressor. Kick starter. He just called me now that his steering rack and water pump are bad.

kneo:
My neighbour is a driver and needs a vehicle (not for ehailing ).
He was affected by Vision Scape closure.
If you can assist with any commercial bus or van or car or.... he is ready .
Please help this family man. I listen to his prayers every night through my window and feel I should just help in my little way

So they've closed down vision scape?

Lovely

I think you guys should just free gazzuzz. Over the years i have come to know gazzuzz. This is my impression of him Which maybe wrong. one arrogant man who hates criticism and think he is always right and guilty of hasty generalizations about others. If you allege something about gazzuzz, instead of him to debunk the allegations with facts, he will attack your personality and starts digging out your past.Very petty. I used hate him but now it is nothing but love.I think he is more honest than most Mechanics and he is very good at his chosen career. i have learnt a thing or two from him

bravolad:
We are strictly talking about the 2010-2011 Toyota Camry with the 2.5l 2AR-FE engine.

Or did @OP mention any other car?

You are right about camry I just checked the owners manual on Toyota website.

Camry 0w-20

but for other cars that use 2AR like Rav4, its 5w-20 or 0w-20

bravolad:
There’s no conflict. You obviously have the wrong manual. Apparently, the oil filler cap on ur engine is been changed.

Even the predecessor engine 2az uses 5w20. So search for 0w20. It’s available

there are 2 oil types you can use for 2ar 0w-20 or 5w-20.

Damilolagboye:
Its the camshaft gear. Have it changed and thank me later. Not a mechanic though but I have experienced it in a car before...

exactly
