5w-30

[Andrace]

What actually matters is the temp of the oil at the rings, in the bearings, and in the turbo, which is different from where it's measured at the sensor. Speed Jr mentions this in a video, some capillary tubing used to sample oil from the rings. will try to find that.

Could be an argument to be made that on average a 5w20 could potentially be slightly more sheer stable than a 0w20 do to less friction modifiers.....assuming the 5w20 is a synthetic.

That's the primary reason I opted to go with 5-20, it's more shear stable and offers more headroom in conditions when it really matters.

Temp is very important. Back in 2017, when Toyota introduced the first Dynamic Force engine (A25A) lots of people freaked out when they saw the 0w16 recommendation. But fast forward nearly a decade, and you have Camrys and RAV4s running around with 200k on them. 0w16 is a thin oil. But when your running oil temps of 170° to 190° that 0w16 stays "thick" at operating temperature.

But I'm not a thick vs thin kind of guy. I say run whatever viscosity that makes you comfortable.

Who's using 5w-30. Lots agree that 0-20 is for CAFE standards or EPA BS. I believe in 0-20 as much as I believe in 10k oil changes.

Any of you guys running 5w-30? Have you done an oil analysis?
Getting ready to do my first oil change at 1k, then switch to 5w-30 pending real world reasons not too?

Well, if 0w20 is for the CAFE standards, I haven't seen any difference in mileage running 5w30 this summer. We have had some 100+F days, so I think it's good for the summer. I used 0w20 in the winter. We get into single digits at times in the winter.

5w30 Used Oil Analysis shows better wear than 0w20 previously did. I will continue to use it. Made a whole post about it for more information.

It should be considered a book at this point

Maybe we misinterpreted the "5w-30" title? Instead of the weight of oil, they meant page numbers..........

8 pages to go

Who's with me!!

I assume you use in in the Canadian winter too.

Tacoma4g would definitely save some hard drive if we could delete yours and Maxx's non contributing posts all the way back to 2024.

Or.....................we could just go with what the manual suggests and delete all of the posts. Think of the hard-drive space we'd save.


So, if we're going to settle this based on saving server space, I assume the debate is officially over and we're taking Toyota at its word?

Well I dove in today.
5W-30 Amsoil Signature Series.
The motor sounds much happier now cold starting as well as at warm idle.
Will see how it goes.
