GM adds new dexos R approved oils

[nordique14]

I see the list of approved dexos R oils has increased since I last looked. As of 3/16/26

I wonder how much this has to do with the L87 debacle? By that I mean, regular people are going to be annoyed that they have to buy Supercar for their T-Ball mobility device (now that Dexos R is the recommendation). I'm sticking with Supercar.

I understand the dealers are now using the Mobil 1 FS oil for changes in the 6.2L L87s because it’s less expensive than the Super Car oil. So yes, I think cost has a lot to do with the expanded list of Dexos R approved oil.

I didn’t know there was a 5w-50 version of M1 Supercar.

Track oil for the ZL1 1LE.

Appears that the C8 Z06/ZR1 uses it as well.

Track oil for the ZL1 1LE.

The ZL1 1LE oil weight for track days is 15W 50. 0W 40 is the oil weight for street use.

The 5W 50 is for the C8 Z06 & ZR1.

You're correct. Sorry for the misinformation. I even checked my notes before posting. Obviously, not close enough.
