Default Made the switch today....

Changed the oil today and put in GC 0w30 and K&N filter HP-2006......So far so good, I wasn't sure what oil was previoulsy in the car but I hope everything turns out okay....

Before I changed the oil today I noticed that at idle the car was at 25 or 30psi which was lower than normalling and WOT was only at 45psi or so.

After the GC 0w30 oil pressure is about 42 or so at idle and around 63psi WOT. And the GC that I got was the green stuff, and I've heard that the new formula is the normal oil color. Looked pretty cool though.
