Do you actually notice a difference running Royal Purple? Just picked up my 07 ZR last weekend, previous owner ran Mobile 1 synthetic and just did a fresh oil change, so it'll be a few months before I'm due.08z719 wrote: ↑Mon Dec 04, 2017 3:46 amAs someone who uses royal purple also, rp recommends using their oil filter to actually have a full royal purple oil change. They also recommend using it for the life of the engine and not going back to other brands. You are spending the extra money on this brand like I am. Might as well do it right. I love rp and will never go back. For my z atleast. Also i use 5w30 for my vq35hr 08.
As long as you use the correct viscosity and correct compatible Oil and Fluids for your vehicle no manufacturer can void your warranty for not using their store branded products. The Magnuson-Moss Warranty Act (P.L. 93-637) is a United States federal law (15 U.S.C. § 2301 et seq.). Enacted in 1975, the federal statute governs warranties on consumer products. ... The law was created to fix problems as a result of manufacturers using disclaimers on warranties in an unfair or misleading manner.ZMEDIC13 wrote: ↑Sun Jan 11, 2009 6:53 amI was thinking of going with Amsoil myself. I used it in my truck before I got rid of it and I never had a problem. Has anyone used it in their Z? How does Amsoil and Motul compare? I also heard somewhere that if you use something other than the Nissan stuff for your tranny and diff that it voids the warranty or something like that...any truth to that?
