Air filter was OEM up to last 2500 miles then Amsoil, oil filter was Amsoil. Car did see 3 tanks of E85 (only E70 in Colorado) mixed with reg 85oct to mix to 93oct total. This may have scewed potassium or sodium or the winter drivinng could have due to road salts. Or its an additive to some point. Coolant system checks out with no leaks and res is full from fall change out. Driving style is unchanged as is fuel beyond the Eth mixing. MPG was steady. Oil was installed in January and sampled in July.

M1 0w40 in it now that I got for 2$/qrt. Actually feels to run just a bit smoother and revs just a bit easier, but I expect more FE wear typical of the M1 at this time.

Thanks for the reviews and thoughts.

0w-40 M1 is real good oil.

Good post. Is the Al = 0 correct?

Are all these from the same lab?

Doesn't look like the M1 EP 5w30 did so well. Sodium and Potassium are at low levels, I wouldn't be too concerned yet.

Yeap, all from Oil Analyzers Inc.

Holy moses your silicon is high. Seems like your air filter isn't doing its job. Do you have a K&N in there or something? Check for leaks passed the air box or something. That's bringing your numbers up, if you ask me.

Actually, I just saw 27 and freaked out, sorry.

Sil in the 20s is almost par for the transverse mounted VQs it seems. No leaks, OEM air cleaner most of the time now Ams.
