Changed to GC today Well, i changed the M1 5W40 to the much acclaimed GC. So far, my oil pressure has dropped. The M1 would sit around 50 psi and the GC sits around 40 just like when i ran the M1 10W30. This oil better be good!

You know what, im going to switch back to it next oil change. I dont really like the GC. My oil pressure is lower and i have a louder valvetrain now. Oh well, i know my car will be fine for now.
