Instead of asking on here ask a certified mechanic what oil is better to run. Personally as an Automotive Tech student we are told never to run anything but the recomended oil. If it says to use 5W-30 then use it. If it says use 15W-30 then use that. Using anything else can cause damage to your engine.

Either I can smoke the hell out of all of u with my RSX or make it a close race with my tour.
