Just got this from ExxonMobil via email, figured I’d pass it on:

Mobil 1 5W-30: 3.1 mPa.s

Mobil Super Synthetic 5W-30: 3.24 mPa.s

This was of interest to me because I use ACDelco Dexos 5w30 full syn (relabeled Mobil Super Synthetic) in my truck. I noticed it made my 4.8 with VVT quieter than Mobil 1 5w30. I’ve been using it for ages, just wanted to make sure it was up to snuff.

I noticed the Delco syn seems to work well with the GM turbos as well.

Not a huge fan of the M1 0 weighted oils ( work well but makes engine loud)

Looking at Mobil regular syn or the SOPUS twin oils for the 0w20 weight for my Equinox
