Is Royal Purple for real???

I had a high mileage civic and RP didn't really do anything. So as long as you have low mileage then it'll work nicely.
 
Only thing I can say I have noticed is the temp on the oil gauge is cooler

Cooler is a good thing!

Yup, that was it.. I think if I ever switch to RP, I still wouldn't wait until 7500 miles for a change.. I think 3500-4000 is a good range.. Not like I'm making 30K a year anyways..

With full synthetic and a good quality oil filter I do my changes at 5,000mi:tup::tup:
