Just finished putting in the RP 5W-30 HPS oil in my car and wow what a difference! The lifters are sooooo much quieter and the RPMs are steady and not bouncing around any more at idle. Prolly gained a few horses and torques!

I will monitor the engine to make sure it doesn't blow up because it's not a Dexos labeled oil. Wish me luck!
