here are the emails I have sent and received from royal purple.
We've never lost a cam with Royal Purple. The problem is todays oils have less zinc in them to help catalytic convertors live. New cars all have hyd roller cams in them so the lack of zinc isn't a problem. Our older musclecars need the additives that RP puts in their product to survive.
In your other cars I'd run the same grade you've been running in Royal Purple multi-grade oil. Racing is better, but it's real spendy. We run Racing only in our racecars. All of our street fleet has standard RP in them.
Thanks, Randy

Is there any truth about not using synthetic in a mechanical camshaft motor? How do you prefer to get paid? What would you put in the two pretty stock 340's that I have also? Thanks Scott

Hi Scott,
The Racing Oils retail for $13.45 per quart, but we sell it for $11.99 per quart. You only need to change it once a season. Get together as big an order as you can because we only charge $8.99 handling whether you buy 1 quart or a truckload.
Thanks again Scott.
P.S. We'll get you some FREE RPMOil.com hats too!

Is that for the xpr20w50? What is the difference in the xpr and the regular 20w50? I work in a large factory with 10-15 guys with muscle cars. We have a blown 392 hemi in a 40 dodge truck, a fm3 pink t/a challenger mine and dads, a 71 340 cuda mine and dads, a 498 roller chevy in a 4x4 chevy truck flat dragger, dz302 camaro, 396 chevelle, 69 396 impala convertible, 78 camaor with a roller 383 and a bunch more. I will talk to some of those guys tomorrw and get there input and see if I can get a large order together. Thanks Scott

Hi Scott,
The biggest thing is to make sure the rings have fully seated. At 250 miles they should be. We make a few easy passes on our race cars with break in oil (Valvoline 30wt or 20w50) then switch to RP.
We sell 20w50 for $6.99 a quart with only a $8.99 handling charge and FREE UPS ground. When you buy from us, you're helping support a racing family, a Hemi racing family (hey that's worth something!)
Thanks and we hope to earn your business, Randy

The car has 250 miles on it since completion. How long should I use regular oil till I go to the synthetic? I have been told not to run synthetic because of the mechanical camshaft, why is that or is it bs? The car is a real 383 4 speed road runner. I have a dana 60 in it with 3.54 gears, msd 6al, hooker super comps with 2 1/8 primary tube, 3 inch flowmaster exhaust and the list goes on. The cam is small at 518/509 245 @ .050. Made 598hp on the dyno and 615 torque. Runs on pumps gas is the best part. I can buy the oil here at oriellys a little less than through you, why is that? Does your price include shipping to 47362? How often would you change it, I am hoping once a year. Thanks Scott

At a minimum, I'd go with the Royal Purple 20w50. Great stuff. But... that car deserves the best, so I'd go with Royal Purple XPR20w50 (Racing 51)
We have a TFX Forged, Brad 5 headed Hemi in our A/Fuel Dragster! Long live the Hemi!!!
Thanks, Randy
P.S. Both oils are of course in stock at

I have a 1969 road runner with a aluminum headed 426 hemi in it. Not a crate motor. It has an eagle crank, manely rods, comp cams mechanical camshaft, j and e 10.25 to 1 pistons and a 850 might demon on a Indy intake. The car sits a lot and only gets 500-1000 miles a year on it. I am in Indiana and the temperature in the summer is usually in the low to upper 80's. I run 20w50 valvoline in it, but I am considering your oil. What do you recommend for the car? Thanks Scott
