 "THE BEST OIL EVER. EVER." 2009-07-22
By John Lo (saint paul, mn)
Royal Purple is expensive but it is worth every penny of it. I bought a brand new 2008 suzuki sx4 and had my oil changed every 3500 miles at the suzuki dealer but I was not satisfied with the performance the crappy dealership oil was giving me so I took matters into my own hands. At 16,500 miles, I decided not to go back to the dealer for my regular oil change instead I switched to changing my own engine and I began using royal purple oil. Now with the car at 30,000 miles I can say there has been a major difference in my engine's performance especially the gas mileage. With the dealer oil, I noticed that my car became sluggish at 2,500 miles and my gas mileage suffered greatly from it. Since changing to royal purple motor oil, the sluggishness has disappeared, the gas mileage has improved, and I don't have to worry about changing my oil every 3500 miles, I usually do it at 7500 miles(changing the oil filter at 3700 miles). If you havent tried royal purple do so already, it is pricey but once you calculate the price of changing oil at 3000 miles to changing your oil once every 7500-10,000 miles you are actually saving yourself money.

By Michael R. Wilson (Dalzell, SC United States)
Best oil out there! Want better gas mileage and higher performance? Use Royal Purple and see for yourself. I use the 5w20 in a 2005 Dodge Ram 1500 with the 5.7 HEMI. It cost more because your getting more in every quart. Try it and like me you won't use any thing else in your car or truck.



See Facts that I researched before I started using Royal Purple. Do the research or try it for youself before you lend judgements on items or comments by those who have. Of course, buyer always beware.

 "Motor oil" 2009-10-11
By Richard Grogan (Ct USA)
Thankyou for your quick service. I have been using Royal Purple for years and I find it to be the best synthetic oil on the market

 "Good stuff" 2009-09-26
By Noel Aguirre (USA)
First time using Royal purple. So far so good, i have in excess of 250K miles on the original engine still going strong and hope to keep it that way for a very long time, of course i'm willing to deep into my pocket a bit more for better quality. I normally prefer not to brag about a product till i'm able to determine it's true benefits over other products. By the way this oil is going into my 1987 BMW e28.

 "Very satisfied" 2009-09-13
By Charles M. Cline (Oregon)
It was mentioned to me by a friend that he used Royal Purple in his rigs, and thought I would try it out. I am glad I did. My Suzuki has 97,000 miles on the motor and it has never, I really mean never run so smooth. We get a steady mile and a half more in gas milage. I am going to change my Tahoe and my GMC over when it is time.

SAE 5w30 Motor Oil is recommended for use in all fourcycle gasoline engines and both twocycle and fourcycle diesel applications including cars, trucks, motor homes, RVs, boats, commercial fleet and stationary industrial diesel engines. Royal Purple Motor Oil is a tough, long life, high performance oil that delivers superior protection and enhanced performance to gasoline and diesel engines. It gains its performance advantages from a blend of synthetic oils plus Royal Purple's proprietary, synthetic Synerlec additive technology. Synerlec additive technology greatly reduces engine wear, including ring, cylinder and bearing wear. It is extremely tenacious, adheres to engine surfaces and remains after shutdown, which provides protection upon initial startup. Royal Purple Motor Oils are compatible with other mineral and synthetic motor oils. Royal Purple's motor oils are API certified and will not void new car warranties. Royal Purple recommends waiting until the manufacturer's first scheduled oil change or a minimum of 2,000 miles in new gasoline engines before using Royal Purple. Allow 8,000 to 10,000 miles before use in diesel engines.

 "ROYAL PURPLE LUBES ARE GREAT" 2009-09-22
By Brian K. Salter (USA)
Tried the RP MAX ATF first, awesome, then the DIFFERENTIAL 75W-140 the mid-grade and it stopped all whining noises (WHINING IS WEAR!!) in my TOYOTA TRUCK rearend, then the RP 5w-30 oil but prefer the 10w's from RP in my older vehicles.

Better than Mobil One, Better than most Castrol Synthetics too.

5w-50 Castrol Syntec is my favorite for very powerful cars but RP 10w-40 is close if not equal. Owning many cars makes the RP 5w-30 the best choice for rarely driven vehicles, even feels slipperier than other synthetic oils!

 "Noticable improvement!!!" 2009-09-16
By EliteTempleton (Michigan)
I was having some overheating trouble that took almost two weeks to figure out. After a couple of thing's didn't fix it I found out about this stuff and it's cooling properties. So I added the Purple Ice to my coolant and it worked immediately(I could tell because I could drive further before overheating) so then I replaced my motor oil and transmission fluid with the stuff, again able to go farther. Once I got the problem fixed, I now have better shifting, more HP, and my engine runs cooler than it ever has! I believe this stuff helped prevent my engine from blowing up while it was overheating!

 "NOTHING Else Goes in My Truck" 2009-09-01
By T. Mabry (United States)
I have been using the motor oil Royal Purple Street Synthetic Motor Oil - SAE 5w30, Quart Bottle, Pack of 12 for 3 different vehicles I have owned since discovering it in 1996. It is phenomenal product that lives up to its billing better than any product of the same type on the market. If you want to protect your engine; only have to change your oil about once every 5k miles, get this oil! Expensive you say? What is your engine worth in comparison? This stuff works and not only their motor oil, but transmission, radiator.. all their product are FAR and away superior to ANYTHING else on the market. For my money, time, and power boost that this product provides to my truck, nothing goes in my crank case but this oil. Buy it, you will not be disappointed!!

 "More power, cooler engine" 2009-08-02
By Carrot Juice (In your mind)
Just switched to Royal Purple today in my 2008 Chrysler Sebring convertible with the 2.7 V6. Noticeably more power and the temp gauge is lower by a hash mark (not sure of the actual temperature) and I'm happy.
