Why can't everyone use 0w-xx?

Now, with a lighter throttle, likely cooler oil... 20 or 30 should be enough, not??

Yeah, I do like the marginal gas mileage gains of lighter oil, also!!

It's marketed to cars with Turbos. I think it was reviewed on a Lancer EVO and compared against 20w50 using a dyno


BMW 335i too.

I ran shell rotella syn 5w-40 in my EVO, but that's because it was cheaper than Mobil 1, and I read it was a "good oil" a million years ago on motorcycle forums. I didn't have a clue what I was doing haha.

I still have two jugs of it on the shelf to sell, ugh.
