royal purple

[saltlake3fitty]

is anyone running royal purple oil? and if so is it really worth the money?

[blackcloud02]

Yes it is 100% worth the money. I run it in everything I have. Ive got it in the motor and both diffs in this truck. Motor, Tranny, and Diffs in my mud truck. Can't beat that stuff up. I would say go for it you'll be hooked.

I would say no.... most of the lab tests i saw with RP showed it losing it's viscosity the quickest. (Among Synthetic Oils)

I was never impressed with it in anything I have run, and some of my old oil reports from my other cars showed it to do just as ToMang07 said, loses viscosity quickly. IMO it's hard to beat a new filter and good oil every 3500-4000, I've run Delo, Rotella, and for this oil change I tried Schaeffer's and can't tell any difference between them. I may try the Schaeffer's again for my next oil change and order a report to see if it's worth the price.

I love it im my harley and my old gas burners but could not tell much differnce in the 6.0. Just switched to rotella t6 5w-40 and love the results. better cold starts and mpg's. Not to mention a hell of alot cheaper.

It's definitely not worth $33 a gallon.

thanks for the replies, the auto store i go to wants 39.99 a gallon for it when all other brands are about 15.00

I've been running it for the past 4 or 5 years, can't tell much of a difference from before. Also it seems like everytime I go to purchase RP the price increases. I've heard good stuff about the Rotella & I am thinking about switching so my pocket doesn't hurt so bad every time I do a oil change

[Zaairman]

Rotella Synthetic is great.

Rotella Synthetic especially at Wali World for $20.00 a gallon, great stuff can't beat it. You see Rotella at every truck stop not RP, that should say something.
