Can anyone give me any opinions on Royal Purple oil? Is it as good as they claim? Is it better to use their motor oil or should I purchase their racing oil? It is for use in strictly street application (68 GTO)

ive read about it but never used it i use penrite fully synthetic oil and its never let me down i also put some slick 50 additive in with it

I`ve heard nothing but good things on royal purple, my father tried it and he`s plenty impressed with it as a gear lube, and he`s got to be one of the hardest to impress I know of.

Its one of the best on the market today. I use all their product's in all my car's & lawn mowers.
It does what the advertisement says it does. Heres the site for them,

I used to be impressed with all the fancy schmancy high tech wizzbang oils, but my experiences have proved to me that if it meets the new car standards, its just fine. Never had a cam go bad either.

I use what ever is on sale at Kmart or Checker. I"ve used the cheapest crap I can get that still meets the car maker requirements. My last 350 had 168,000 miles on it when I pulled it out, ( and still running fine). My current 350 has 142,000 miles on it and is in super shape.

Last good deal I got was "Car and Driver 10w30" brand at Kmart for 29 cents a quart, on clearence. Currently, I buy the 5 quart jug at Walmart for under 5 bucks.

Then came the testing of all the "killer teflon additives" that proved out to be not much more than snake oil for you engine. In the roller bearing friction test, they proved that Canola oil ( french fry cooking oil!) out did most of the "special additives".

Some additives might be ok and help somehow, but over the life of the engine, how many hundreds or thousands of dollars more are you spending for them, compaired to how long the engine lasts?

Just my 2 cents worth, and i'm sure some one will offer me change!! LOL

Royal Purple is very good oil, just like all the top name synthetic oils. Mobil 1, Redline, Amsoil, and Royal purple are all so close in independent tests that the difference is negligible. All syntheic oils break down at a much higher temp than conventional oils, your seals will go before the oil fails.
