Well mostly VQ series engines. The VQ is a bit hard on oils and RP just didn't do well.

check this out taken from the Mobil 1 website...seems like there are Esters in Mobil 1?

Is Mobil 1 an Ester Oil

Decide for yourself if you want Mobil 1 or not

RP does just fine in mine. Been running it for 18,000 miles so far and 60K+ in my last car. Here is a good test, RP is one of the best.

This article is thrown around a lot by Royal Purple users. This test is really only designed to see if an oil has extreme pressure additives in the oil formulation. It is not a measure of how well an oil performs, although this test leads people to believe so.

I've had great success with used Harley-Davidson oil from my bikes which came used from my vette which came used from my Kia which came used from my John Deere lawn tractor which came used from my deep fryer.

..those additives are better served in gear oil due to their corrosive nature..

someone show me definitive evidence that RP does more harm than good, because i've researched all over the place and found nothing but heresay, Jordo seems to know a bit, whats your take?

i read prolonged use of RP will eventually corrode and blow the motor up haha

..nobody's saying that RP is bad..it may very well be the best..or the worst..haha jk.

wishihadnav · 07-22-2010, 06:59 PM

were just saying that a 4ball wear test is not a good indicator of oil performance in engines..that's all.

Ya well turns out I'm at 220 not 230

Blackstone will tell you how your engine is responding.

I'm currently running RP, having searched the 350z forums RP doesn't seem to be the best... =(...

Neither does Motul to be honest... Redline's hard to find in Australia...

Castrol Syntec 0w30 and 5w30 seem to work pretty well in my motor.
