Outside of the US the newest toyota engines which spec 0w-8 can go up to 10w-30. I wonder if Toyota will at least give the same broad oil selection the rest of the world gets now that the new sheriff is in town.
GM now saying to use 0w40 in 21-24 6.2L

Thicker oil: takes up the slop if there's slop, and when the clearances and specs are correct, separates parts better for less wear?
Thanks. I figured as much. It's not a solution at all. There is a mechanical/manufacturing flaw.
Also, engines can run on multiple viscosity grades as most have said for years.
How many other vehicles from all automakers out there are out of spec, and to what degree are they out of spec? Nobody knows. But likely there's variances, so if thicker oil is used from the start, then could it not provide a buffer for those variances? And could it not also protect all engines better, for longer, regardless of the spec?
I don't know, maybe you're right. I'm skeptical the viscosity increase will make a difference.
Yes they are attempting to mitigate a material or design defect with increased HT/HS. So it is using a thicker oil as “better”. Increased film thickness is the objective.
Of course they aren’t the first to try this. Maybe it will help somewhat for some period of time until they get a permanent solution worked out. But it’s still a bandaid on a problem for now.
When you think about it, all by itself that part is pretty cheesy. Would it really cost that much to print new manuals?
Low oil pressure from the variable pressure oil pump is likely the cause of the engine failures especially if it begins at the valve train.
Hydraulic actuated switches and solenoids require high oil pressure to operate properly.
Is there a way to defeat the variable pressure oil pump?
Can it simply be unplugged?
Even if it worked, wouldn't that throw a CEL, and then not pass inspection in many localities?
It will. On my Tiguan I had the variable pressure solenoid fail (high) and it eventually gives a CEL after multiple drive cycles. If it fails low then it gives a flashing CEL with a warning about engine RPM. There are only two levels, low and high.
But I'm sure that as part of a fix or recall the ECU could be reprogrammed to only operate the pump at high pressure and they could suppress the CEL.
If the pump can handle that constant higher duty cycle.
That would be some poorly designed pump. As in shearing off the drive gear? That's the most often red herring fear.
I believe it does. I think the l87 and l8t use the same pump.
If you live in a warm climate use 15W-40 , in a cold climate use 5W-40, why just optioning 0W-40?
Oh yeah 0W for gas mileage.
They finally figured out sewing machine oil viscosity doesn't help their products last past warranty.

How hard would it be to swap out an oil pump from a 6.6L truck engine?
The same oil pump has been used since the 2014 model year on all Gen V engines. The lifter issues are not caused by low oil pressure or have these engine had low pressure issues.
Printing is expensive these days I think.
I was thinking 0-40 so people would have to go to the dealer for an oil change, or to buy their expensive 0-40 dealer oil that you can't find anywhere else.If you live in a warm climate use 15W-40 , in a cold climate use 5W-40, why just optioning 0W-40?
