Anybody running Royal Purlpe Synthetic Oil???
Anybody?? I'm thinking in switching from regular oil to Royal Purple.. Hot Rod Magazine tested it and they got approx. a 6 HP improvement in engine output... So I wonder if anyone has tried it already??

I switched to Royal Purple in my trans and noticed much easier shifting which Richmond's are not known for.
I was advised against synthetic in the rear differential because it will not cling to the outer bearings. True or false? Don't know.
I did switch to Mobil One two years ago and imediatly spun a main bearing.
If it was the fault of the oil or not, that made me leery of synthetics.
I am swiching to a new oil this winter, it has all the properties I'm looking for. You can check it out at http://www.oilextreme.com/ .
If you do decide to go with Royal Purple, go with their Racing 21, it's better than their standard replacement oil. Thats 3 cents change on a nickle.

Re: Anybody running Royal Purlpe Synthetic Oil??? (GrandSportC3)
I have yet to use it, but that's only due to the price and my opinion that my current well worn engine is perhaps not worthy, but my Corvette mechanic swears by it. He has a high performance modified '80, and that's all he will use. Every time I drop by his shop for an oil change he asks if I'm going Royal Purple. He has to order it from the main Napa warehouse in town because the stores here generally don't stock it. When I get my new crate engine it will be Royal Purple Synthetic as soon as it's past those first few initial miles.

Re: Anybody running Royal Purlpe Synthetic Oil??? (GrandSportC3)
I've run Royal Purple in my 98 GMC Z-71 pick-up for the past 4 years, Mobil 1 prior to that. After 110,000 miles, the motor still runs like new. I switched to synthetic at 1,500 miles. Never noticed any power increase, but afterall, it's a truck not a hot rod.
I plan on running Royal Purple in the Vette after the break-in period is up on the ZZ4.

I've used Royal Purple in my daily drivers for approx. 4 years now and really like it, but can't reinforce any claims on gained HP.
Unfortunately I can't use it in the Vette - engine has original (circa '72) seals that do not like synthetics, so it gets Castrol GTX.

They baselined it, then did the oil change. 5hp gain. Then, the techs demonstrated how it actually polishes the metal surface while it works. They used a main bearing, if I remember. Worth the money, IMHO. Of course, I use Mobil One, only because it is the factory recommended oil for my 00 Nassau Blue FRC. (one of 189. :D )

Re: Anybody running Royal Purlpe Synthetic Oil??? (Corz)
I've been in touch with Royal Purple for a few questions and they were very nice and didnt try pushing anything off on me. I am deffinately putting it in my ZZ4 after break in period. NO DOUBTS!!!... However I am not planning on putting it in the tranny of rear but thats just because they are both old and worn most likely and like someone said before not quite worthy of it. More so being I want to use what they are used to being in them.

I had some in my 69.. I'd stay with that brand if you go with it.. I too spun a bearing once I did an oil change (went with castrol syntec). I should have spent the extra 10 bucks for the RP again :cry

Re: Anybody running Royal Purlpe Synthetic Oil??? (GrandSportC3)
Now the question is.. What viscosity should I use???
I currently use 10W40 which was recommended by the engine builder... I guess I will go with the same viscosity from Royal Purple...

Re: Anybody running Royal Purlpe Synthetic Oil??? (GrandSportC3)
not bashing royal purple at all but just to clarify, it's not a true synthetic. it is an engineered hydrocarbon (i.e. petroleum) oil. a true synthetic would be a diester, glycol or polyglycol (and a few other concoctions) formula.
i know this because royal purple got it's start for making oils for rotary screw air compressors. it just so happens i run a company that does rotary screw air compressor sales, service and repair. the demands of a compressor are quite different than that of an internal combustion engine and require a different formulation. a regular hydrocarbon oil in a compressor has approximately 20% the life expectancy of a true synthetic. just in case you were wondering, a glycol or polyglycol based "oil" formulated for use in an automotive engine would probably cost somewhere around $20-30 a quart.

Re: Anybody running Royal Purlpe Synthetic Oil??? (shoptek)
I run Royal Purple in my 81. I think it's great oil, and I've seen a lot of demonstrations and magazine reviews where it outperforms many other oils. It really is some good stuff. I know it's pricey, but my vette deserves the best. I haven't tried the Royal Purple ATF or rear gear oil, but I plan on it. They also make power steering fluid, as well as an antifreeze additive. But I haven't heard much about those. I also run a K&N oil filter, as I've heard those are the best.

Re: Anybody running Royal Purlpe Synthetic Oil??? (Jasonty)
Ahh jeeze. I have a feeling I'm going to switch over from Havoline conventional to Royal Purple synthetic. Maybe it will slow the ware on my old L98 and extend it's life a bit.
