Thanks for the help guys - looks like I'm gonna go with PP because of all the good things and used oil analysis I've read. I might work in some PU changes (once every 5?) if I start seeing some positive used oil analysis of that, if only for the enhanced cleaning ability.
I will prob stick to...
It's in an 03 Civic Si hatchback.
Do they sell PU by the gallon? I can't seem to find it online. How much more expensive is it than PP and what are the advantages?
1. What kind of vehicle you have
I have a freshly built 2.4L engine with mostly Acura TSX components. For the purposes of this thread I think it's safe to assume that it's a TSX engine with slightly higher performance (250whp).
2. What your owner's manual says
I believe 5W-20 is in the manual...
