I read warmonger's post about how he only uses thicker oils. I'm in the same boat also. I'm just curious as to what oil weights other people use....
personally i do 10w30 or 10w40 in the summer... in the colder months, i'll run a 5w30 oil.... i won't touch 0w anything.....
my setup is just a straight 3L swap, oval port heads and intake, with a 75 shot
so what's everyone else using... and on what type of setup....
2000 Cougar V6 MTX
2001 3.0L Swap w/ PnP Heads - It ran, it boomed, it RUNS AGAIN

Nearly all suspension mods
Big ass stereo
...and more...
