My girlfriend owns a 1997 Saturn SL2 that requires 5w-30. Her mechanic always puts in 10w-40 bulk oil every 3k she gets an oil change. The mechanic says there is nothing wrong with 10w-40 instead of 5w-30. Is this true?

So, to me the main thing is keeping the oil topped off. The weight of the oil is secondary.

Yep... My Cousins uses 1 Qt every 1200 mi and gets SuperTech 10W-30 out of a 5 Qt Jug. He changes the Filter Every 12 Months (Pure One) and drains it every 3 years. After all its a self changing automobile (5 Qt Every 6000 mi).
EDITED: To correct my Math!
