Oil
 

Will someone please give me clarity on the oil grade that is supposed to be used?
manual says 0W20
Toyota Says 5W30
Toyota tech Says 0W20 but service invoice states 5W30, so which is it?

Thanks in advance.

Ow20.

use 0W-20 as this is what the engine was designed for. You can use 5w-30 for track sessions (if you don't have an oil cooler) but I would not use it any longer then that.


If you are thinking about switching viscosity's for any reason please do some research first it is not always a good thing, in many cases a thicker oil (then what it was designed for) is bad for your engine.

Team lava saves the day once again :cheers:

NO to the above.

Please ignore what you've read, and don't use 0w20.
Especially opinions from cold countries overseas which are wrong for our temps and our local conditions.

Use 5w30 per Toyota SA specs.
They've got it right for our local conditions (today 40°C - 0w20 - you must be joking).
Trust your dealer.

If in doubt, check it next time - this is the right oil.

Oh, and I use it, and my engine does not use a drop of oil after 3 years, and 26 days on track.

oil is not what it used to be. Even in +40C 0w-20 is fine. not until your oil hits ~300F should you really be worried (talking synthetic 0W-20 here).

From the SA manual. Spec of 0w20 is sufficient even at high temps up to 44deg celsius.

Oh stop it.
You are totally misinforming the OP.

So you're recommending he must put 0w20 in his car?
And throw away his 3 year warranty and his service plan, because Toyota will void that instantly if he puts anything other than their oil in his car.
They don't recommend it - they insist on it. It's what HAS TO go into his car QED.
Oh, is that what happens in SA? The wrong grade will void his warranty? Duh-yup.
Oh, if he happened to put oil in into his car himself, even the right stuff, that would be a problem? Duh-yup.
Are you crazy?

To the OP - please re-read my post, and if you have any questions then PM me.
I'm not prepared to argue with someone from overseas bombing into our local forum with his wrong opinions.
Beware, he could cost you a moer of a lot of money.

PS: I'm out of this thread, but I do hope that that some other South Africans chase you back where you belong.
Maybe you meant well, but you're wrong

Dude the car is factory filled with 0w-20 and as per Toyota/Subaru (not the dealership) the car is to run 0w-20 and 5w-30 can be used when needed or in hot climates, but 0w-20 is still the required oil for the FA20 engine. Why would you want to give up power and fuel economy by going to a thicker oil that is not going to protect your engine any more. Do you even know anything about oil. I bet you are one of those people who think the "W" stands for weight, however it actually stands for winter and the first number is the viscosity rating the the winter so you get an idea of cold start viscosity. You want your oil as thin as possible on start up as 90% of engine wear comes from starting the car when its cold (has not been started for 8 hours or so would be considered a cold start even in +40C) The reason you want it thinner is so it can flow to all the areas it needs to be to lucubrate. The second number is the viscosity rating at operating temp, 212F or something around there if I remember right. A thick oil at temp will be harder for then engine to pump and therefore rob fuel economy and power (not much but it does have an impact) Maybe you should get with the times and learn about modern oils. Yes back in the day a thick oil was good, with new oil technology you want a thinner oil. Plus dont forget that tolerances on modern engines is much tighter then they used to be so I would not want to mess with something that Toyota and Subaru spent millions developing.

Don't be afraid to use 5w30. Thin oils is all about emissions and legal requirements . 5w30 oil should be fine in South Africa for daily driving. If you track the car you have to use even a higher grade. How much higher depends the duration of the race.

Modern synthetic oils are very durable to high temperatures, but thick oils are still in use. All the big guys here with the Porsche's are filling their engines with very thick oils before going for a race.

To be totally honest getting a proper oil cooler is your best bet if you track haha

Yes an oil cooler helps.

It is really funny that YOU are lecturing the people who say to put 0w20 in the FA20 engine.....


This is a direct cut & paste from the owners manual:


"If approved engine oil is unavailable, another motor oil of matching


quality can also be used.


Oil grade: ILSAC multigrade engine oil


Recommended viscosity: SAE 0W-20


SAE 0W-20 is the best choice for


good fuel economy and good


starting in cold weather.




Oil capacity




(Drain and refill 

Without filter


With filter


5.5 qt. (5.2 L, 4.6 Imp. qt.)


5.8 qt. (5.5 L, 4.8 Imp. qt.)"


And it says RIGHT THERE "If approved engine oil is unavailable, another motor oil of matching quality can also be used."


So you are wrong on multiple counts.....
