Has anyone ever used Royal Purple oil?

I use it and like it. From time to time il help my neighbor who runs his own lawncare service so I might need to pick up a bed full of mulch or whatever. My trans is definatly a lot smoother since I switched out the fluid. Just going through the gears was a difference. I buy the oil bulk from ebay. I get an entire case of motor oil (12 quarts) for about 65-75 shipped to my door. I always change the oil when I notice it turning color which is usually 6 months or less. So 75 bucks a year covers my motor oil for the most part. Seems like a good enough deal for me. I cant complain with the results I get.

I agree that Amsoil is a good oil with a bad marketing plan. It's also a group 4 but doesn't have as many cleansing agents and is meant to have a very long change interval.

RP will go 10K easy without needing a change, AmSoil supposedly can go 25K in a new, clean engine. Most people who use group 4's will change their filters every 2-3K miles and just top off the oil until it has 10K on it, then change it. It's actually cheaper in the long run.

Scamsoil products have inflated prices due to the MLM structure! The long change intervals are just marketing hype to try and justify the high prices, nothing else!! Remember, Scamsoil is just a blender and packager, they buy their base oil stock from REAL oil companies!!

I switched my Buick over to RP a couple weeks ago. So far I've seen 1mpg difference driving normally. I say if you're gonna do it shop around. I bought a case of 12 on ebay and got it for 6.60 a bottle, better than the 7.25 everyone around here sells it for! I did it because the car is supercharged and I DO plan on doing some upgrades. Plus I was curious, always wanted to just try it to see how it would do.

Well, here is my take on the oil thing...

There are times that I will turn my truck on, and for 48 hours straight keep it running short of the few breaks for fuel or the short nap I might take when plowing. When I am plowing a blizzard for 48 hours like I was a few weeks ago, my truck is in 4hi the entire time, with the plow dropped going back and forth all day long.

Now because of all this I recently had my tranny flushed, cleaned, and refilled with RP Max ATF and I can honestly tell you that the truck shifts more firm and it runs on average 10-15'F cooler then it did before. I know this because I have a tuner in my truck with a digital read out and I am ALWAYS looking at my temps when plowing. There is not many things that can be considered higher abuse then plowing, and for that reason, the added cost of a high quality synth fluid is well worth it to me.

In the motor, I run motorcraft 5w40 full synth and have been since new. The tolerances in the 3v triton motors is so tight that the owners manual recommends it and the truck came filled with it so I stuck with the program.

RP might be overkill but I see it as cheep insurance. 10'F could mean the diffrence in a new tranny for someone like me.


And yes, I know my clutches will still go with all the F to R, F to R all day long but thats just part of the business.

it didn't take me long to figure this one out! LOL
