This should be a pretty good comparison of TGMO and AFE. This is the 2nd run, but 1st UOA of TGMO. The 1st 2 UOAs, as indicated in the report, are with M1 AFE. I have to conclude that TGMO is on par with, but no better than, Mobil1 0w20 AFE. I don't plan to make any extra effort to seek out TGMO in the future.
For me, TGMO is a big "meh".
I welcome input as to Blackstone's comments about aluminum. Not sure if I should worry. Not sure what I can do about it, anyway.
I noticed last Spring that the OEM air filter did not seem to be sealing well. I replaced it with a rather pricey Mahle, with a nice foam gasket. I tend to think that the better filter helped drop the Silicon by 33%, which wasn't very high to begin with. But the number was trending downwards anyway, because the engine is relatively new. So who knows how much can be attributed to the new filter.
Comments?
Code:
We can't argue with these numbers. Metals line up well with universal averages and past reports,
so we're not seeing anything that would point to a problem. You'll notice aluminum was twice the average
value, so it was close to getting a mark. It's from the pistons/bearings, but even this level isn't enough to
cause concern. The flashpoint got a mark this time, but it's not a major concern. It shows a trace of fuel in
the oil, but that's a harmless amount and isn't enough to cause or show any problems. Your engine looks
good from here. Keep up the good work!
