I guess you would need to see a previous one to say good, bad or indifferent

. I wonder if the oil thickened up or he put in some 15W-50 in. I'd say the Mobil 1 did a good job

Pretty good.
I'd bet the air filter had little to no miles at the start of this run.

Very nice. M1 of all oils, seems to be doing well in LS1's lately. Go figure.

Also notice the viscosity though too. Whenever we see M1 doing well in an LS1, the viscosity is also higher too. I still believe the LS1 likes an oil around 12cst, so when we see these UOAs on M1 where it's getting in the 11-12cst range, that's why it's doing so well. When it's closer to 10cst, that's when the wear numbers aren't usually so spectacular.

Copper of 24 in an LS1? Wow! That's almost unheard of. But it's a good thing.

Yep, eventually you'll see that copper come down to almost nothing too. By the time this engine gets about 10 to 20k more on it, the copper won't even be an issue (not that it's harmful earlier on, just kind of annoying to see on the UOAs)

Very good report for M1 and this LS1. I hope mine looks something like that.

To all of those who think M1 is not good in an LS1.
