Well when you pay that much for an oil you generaly expect it to out perform far cheaper oils like Mobil-1,PP and RTS etc....... Normally one expects to get something more from a product that cost's more then other products more easily available.
I have always been very clear with the fact that Royal Purple isnot a bad oil it is just far too expensive when it returns results no better then Mobil-1,PP,RTS 5W40,Amoil and Redline which are all cheaper then ROyal Purple!!!! TYpicaly their Race Oil's are on par with Amsoils and Redlines regular non race oils but again they often cost $3-$6 more per quart then either Redline or Amsoil.
With reguard to their Gear oils well lets just say they do not hold up to extremes like Redline or Amsoil gear lubes and their various MTL like products are absolutely worthless. I tried them and in my TOyota they lost their cold weather performance by 10,000 miles which in a cold state with long winters like MIchigan has is unacceptable of a premium priced synthetic lubricant.By comparison I get about 40,000 miles of excellent cold weather shift performance with Redline products before I start to experience a subtly degradation in shift fell ans such.
I actually find it repulsive that I cannot buy a Hot ROd,Mopar,4X4 magazine or watch anything on SPEED Channel or SPike TV with out having to listen to people with less oil knowledge then my 11 year old son push Royal Purple Products every chance they get!
I can live with the shearing of their oils even though I think it is odd that any synthetic 5W30 would shear that badly but I do demand a price that is inline with the performance of the product! I am not the type make purchase's based on marketing and fad's with in a sub-culture. THe only reason I spend the premium money on Redline gear oil is because it offer's me performance that I can not get from OTC products so the premium price is due to added value not because I am paying for agressive marketing plan! I do not pay the premium for their motor oils because I do not need a POE synthetic with beefy additive package to go 6 months or 10K miles OTC oils that are far cheaper can do this.
So while this site is subject to much hype German Castrol,Penzoil Platnium etc........FOr the most part few people on the site are the types to just toss money to the wind. Many are frugal and with out much more drastic performance difference between RP and other cheaper synthetics not a lot are going to go googoogaa gaa over it!PP was for a long time dirt cheap and it offered sludge cleaning as an added value. M1 0W40 also ofer's sludge cleaning as an added value but M1 onlymentiones it on their sight not on the side of the bottle.
Marketing hype is one thing we are more immune to on this sight. Not so much these days as the number of professionals in the field of tribology,chemistry, or automotive industry has dropped and more and more average Joe's have joined up. Marketing is for those that do not and will not seek out technical information to make non-emotional decision on purchase's! I hate front wheel drive cars and I hate 4 cylinders in car's but I am driving a front wheel drive Camry with a 4 cylinder because that was the practical thing to buy since I got it with everything but a Sunroof and mag wheels for $17,000 brand new with 4 miles on it.Had I bought what I wanted I would have a 4Runner or FJ Cruiser in the parking lot right now!Same thing or same type of non-emotional reasoning is how I pick most lubricants. A combination of utility, cost and any value added.
