10w40

Can the VVt system on the 2.7 handle 10w40? Been running 10w30 with no issues. Appreciate it

 

Yup, no reason to 40 unless you’re in a balls hot climate though.

If you see cold weather, it needs to be 5w30 or 0w20 ideally.

 

Compare the cSt @ 100*C values of the oils. There are "thick" 10w30s that end up thicker than a "light" 10w40.

But why deviate from factory spec? The engineers knew what they were doing.

 

I have a lot of miles 300 k and it runs better with the thicker oil

 

I wouldnt simply due to thin passages on the VVTI system. I'd only recommend 10W40 for Arizona or Mexico with the 2.7

I've worked on Toyotas a long time, 5W30 would benefit your truck more than 10W40. The easier start up with better cold weather rating in the morning puts less strain on an older engine.

 

Thanks guys, was just curious

 

I have been liking how my truck is running on 10w30 and I use hyperlube which helps with the cold start ups. You think it's ok? I won't go back to 5w20 but might go back to 5w30 if you think that's better @Bishop84

 

Yea 30 is fine, the 2.7 is a trusty work horse and the 30 makes more sense in your mileage case.

5w30 would be great.

 

I'm amazed how much of a workhorse it is. It runs strong and no signs of slowing down.

 

Define "runs better"...

 

why would anyone chose 10w cold when there is 0w and 5w

 

I ran Mobil 1 0W-40 a couple of oil changes. Worked fine, but really no need to deviate from the factory 5w-30.

 

I'll use 5w30. Has anyone ever used 5w40? any benefit besides summer time?

 

Is full synthetic or synthetic blend better for higher miles? I change my oil every 3k.

 

You'd think so, but not always. Although I would think Toyota engineers are well seasoned.

 

Still waiting for someone to define “runs better”. Over the years in numerous vehicles Ive run dozens of different oils and viscosities and I’ve never noticed a vehicle or engine actually running better or differently due to the oil I was using. It may actually be performing better in some small way but nothing you could actually see or feel.
In any event we will never ever ever agree on the best oil to use in any vehicle.

 

What does the owner's manual say? No need to second guess the engineers...

 

Yeah I don't think it matters. Kind of done with the the oil weight discussion. Thanks for the feedback

 

@Bishop84 Synthetic vs synthetic blend for 3k interval's?

 

5k synthetic. It’s been proven that dumping good oil early doesn’t do any good.

Honestly bulk cheap oil is all it needs, whatever 5w30 is on sale.

These engines only fail from low oil, not oil quality.
