yes, in a GM engine with an M1 EP oil.
I wanted to know because I ended up putting in my wife's Saab 97X that has a GM Vortec engine.
I wanted to use M1 5w40 TDT, but Pepboys was out of stock because they were doing the 5 qts + oil filter for $24.99 after a $5 mail-in rebate.
I wasn't going to go down the street to pay $7/qt.
After seeing this report, I won't be going to the 10k that I was hoping for with this oil. 5000-7500 range might be all it's good for.<ul><li><a href="http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_Extended_Performance_5W-30.aspx">http://www.mobiloil.com/USA-English/MotorOil/Oils/Mobil_1_Extended_Performance_5W-30.aspx</a</li></ul>

it's not that much $ for oil twice a year.

Are you using alot of fuel additives? Do you have a chip?
Detonation and/or funky fuel could draw out lead. Your EP thickened a lot, and the extra visc did not even seem to help. Probally getting high oxydization. If you are really hammering the engine, especially when cold, that would also bring out a lot of lead wear.
Aluminum is still very low, I wonder if it tracks with bearing wear in this application. High Moly formulas usually help with lead wear, not here. I think the oil is still too thin. I would go 5w-40 or 10w-40 or 15w-40 HD and resample. Plain Pennzoil Yellow is a good starting point, maybe the 10w-30 in winter and 10w-40 in summer, at 6000 miles. M1 EP is a total skiparoo. For kicks, try M1 0w-40 at the same interval, that would be interesting.
