Sample of M1 0w40 at changeout for M1 ESP 5w30.
7K miles / 160 hours. Engine still modified to near double torque and HP from factory. I am NOT gentle on the engine.
Fuel dilution due to short trips. Engine was also not fully warm before sampling.
2 miles from work, 1.5 miles from shopping, 7 miles from the post office. Drive to work sometimes requires zero to 50 MPH with gusto on a cold engine.
