Original owner running M1 15W-50 now as I got high iron (28) on M1 TDT last 4000miles. No gears or clutch in my oil and no Iron in the block. I hope my Camshafts are still intact! The TDT also ended up about a thick 20weight. I will send this tired 15W-50 off for OA this weekend.
Fill'n up with Valvoline VR1 20W-50 this time...it was just TOO CHEAP at AutoZone to pass up!
