Engine oil changes coming.

There are also efforts to add two new low viscosity grades to the list of those currently covered by North American specs. At the June 29, 2022 Lubricant Standards Group meeting, API’s Jeff Harmening made a formal request to add SAE 0W-08 and 0W-12 to the ILSAC GF-6 list of available viscosity grades.

“It appears that some OEMs are already using SAE 0W-08 and 0W-12 as part of other industry specifications like JASO GLV 1,” he said. “API should proactively prepare to allow these grades as part of EOLCS [the Engine Oil Licensing and Certification System], therefore we are asking the Lubricant Group to consider this request.”

So I can just refill my crankcase from my kitchen sink now ?

Just because a lubricant is more viscous does not mean it lubricates better...

But no.

However, a 4 cSt fluid is about as thin as you can go...

So when are they spec-ing 0w00? And can they go even lower than that?

Yup, my point exachary.

How about oil usage (burning) ?

I wonder when the gas engines will have rolling element bearings on the crank.

Water at room temp is about 1 cSt; at 100°C its a lot lower, sarcasm.
Also water has very poor antiwear properties. And as frictional as you
can be it will never work.

Oil burn, no more than your clapped out POS you drive now.

ICE will never have rolling element bearings.

I thought you had mentioned before about the lowering of viscosities (for improved mileage) was causing higher than normal oil burn rates in new vehicles.

2019 F-150 here sir.

2 strokes use needle bearings on the crank & rod.

FWIW would a change to the bearings allow longer oil change intervals ?

I can see diesels not being able to use a rolling element bearing. The pressures
are too high.
