Running heavier weight oil

Is anyone running heavier weight oil in the v6? 0w20 just seems a little light.

 

Well it is Friday.

 

Yes, some have.
And for no valid reason in my opinion.

I'd recommend sticking to 0w-20.

 

nevermind...i found the thread

 

I only asked because i read an article about low speed preignition on direct injection vehicles and it said the lower viscocity oils played a part in it.

 

On a serious note, I've heard 0w-20 is recommend for fuel economy ratings. Whatever the owners manual recommends is what I'd use.

 

Oh, they gon die.

 

Mainly occurs in Turbo charged DI engines.
The 3.5 doesn't have this issue. It doesn't have a turbo and cylinder pressure is not an issue.

 

LSPI is more down to the formulation of the oil than the viscosity.

Run whatever you want from 0W-20 to 15W-40, it will be fine.

 

...and oil

 

Ive been running 5w-40 for the last 20k miles

4-5k mile oil changes

 

Another Friday thread!!!!

I mean, why not try what internet trolls do, instead of what the manufacturer recommends....

 

EPA says 0w-20....

Manufacturer says anything from 0w-20 to 15w-40

 

Toyota is more worried about meeting epa regulations than longevity past the warranty period

 

For those interested, research what can happen in a VVT oil actuated engine running a heavier oil.

Are you going to get timing codes in a 2GR? Probably not. (like 99.999 it wont happen)
But one needs to know what consequences can happen if they give bad information.

 

Can you post a link to the thread? Thanks.

Can you point to a place where Toyota says that a heavier oil, say 5W-30 is OK in a 3.5?
