Since I am not an expert in oil I was curious if there would be any benifit to running a 10W-30 oil vs. 5W-30 for a vehicle that is only driven in the spring and summer where the temperature is above 40F.
The vehicle asks for a 5W-30 but 10W-30 is listed ok in the owners manual. This is for the 5.7 LS1 engine (04 GTO).
Would I gain any benifit or would I actually be better sticking with a 5W-30 or 0W-30. I am currently using the 5W-30. I am more concerned with HP and/or wear protection gain/lose between grades.
The oil would be M1. $22 @ WM
