I've used Royal Purple for the last 4 years on my modded Acura TL-S and this lightly modded G35c. We have a lot of Mustang/Vette guys around here at the local race shops and they all swear by RP. I used Mobil 1 before, and I, too, think RP has less consumption in general, and it seems to actually make the car run smoother. I also think if you feel a power difference in your oils, it's because you drank some of it--any gains would be negligible...

I've used Mobil 1 for the past 10 years and don't have any complaints whatsoever.

According to pretty much every test (I've seen) Royal Purple is consistently among the worst oil available as far as synthetics go.
I use Amsoil as they are the only company out there that really goes out of their way to prove that their oil is superior to all others.

Really though, any synthetic will provide superior protection to a conventional.

DO NOT use royal purple. I just used it for the first time and now my engine is being rebuilt because it spun a bearing and alos messed up almost every other bearings. The machine shop said my bearings look like a lubrication problem and they also said that royal purple sucks. They said to use Mobile 1.

I'm currently using RP 5W30 with zero issues but have a garage full of Mobil1 0W40 european blend I ran in my VW GTI turbo. Should I have any issues here if I start using the M1. I hate to let it waste.

Man i ran M1 and and RP both are great. Both have a crazy following. But honeslty, mobile 1 changed there formula , and last i heard was minorly inferior to RP now and Amsoil. But amsoil is the best bar none in my opinion goodluck finding a place that has it lol. RP would be my second . M1 is now 3rd. If they had kept there original synth formula they would be my second.

its just like this page( http://www.royalpurple.com/techrp/summary.html ), whats cool here is that trucks the show did a nice review of RP . And other shows, which arnt sponsered by them , but honeslty its preference as long as its group3 or 4 your good unless you have a completly built block race savvy setup then oil is everything. But the performance per buck per hype never adds up .

Currently available exact equivalents to NISSAN Genuine ATF Matic Fluid J are Castrol Transmax J or IDEMITSU ATF HP.

Its the best but in reality, unless your sponsered by them why spend the money if your not going to reap the benefits like a race team would lol. I go back and forth between m1 and RP but now im probalbly going RP all the way through.

Amsoil has been independently tested against pretty much every well known synthetic out there and has been shown to provide superior protection in nearly all categories. Thats not to say RP, Mobil 1, etc are not good oils, just that Amsoil is better.
And to the guy who said you can't find Amsoil, go to their site and do a search for a local dealer, I bet you theres one closer then you think. Or you can order it online; thats what I do and I get it in 2 days.

I changed my tranny fluid, rear Nismo diff. fluid and my engine oil over to Royal purple. Couple years now and I have not had any issues. My manual tranny feels smoother and my rear diff. feels great. As for engine oil, sure looks better than the standard oils I used in the begining. I think I will stick to RP.

jonb, Amsoil is about $6-7/quart. If you're going to buy direct and use Amsoil products consistently you're best going with a preferred customer account, then you get dealer pricing on all their stuff. Its only like $25/year or something.
I use Amsoil in my engine, tranny and diff. I also use their Eao 25,000 mile oil filters, and amsoil engine flush.

Because of this thread, I just got my AMSoil change done about an hour ago..... Feels a bit different, smoother...
I have been on RP for the last 2 yrs, but AMS was a bit cheaper too.. Not by much though..

In past cars I have used RP did not like it. I then used mobil 1 sythetic and it was better. Since I have one FI car and the Z Amsoil has performed flawlessly in hot and cold conditions and with sprited driving. Its worth the extra cash in the long run. Just my 2 cents!
