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.
I love motor oil and I love experiment with it too. I have a 2009 Acura TL and I only have 5000 miles. I didn't know how long the factory fill oil was sitting in my car when I bought it so after 1000 miles I changed it out to Red Line 5w20 because it is simply the best oil(polyol ester oil) when it comes to its additive pack(ZDDP-Zincdithiophosphate and Molybdneum(friction modifier). Now after reaching 5000 miles I decided to change my oil and decided to try Royal Purple 5w20. After researching the web and reading quite a bit on an oil forum, I was a sceptic because it wasn't received well. I heard everything from it shears easily and doesn't hold its viscosity to the fact that many used oil analysis(UOA's)didn't show favorably on Royal Purple's side. Well after having this oil in my sump for over a month, I can honestly say from the bottom of my butt dyno that I love this oil. I don't know if it is in my mind or not but I feel that I have better low end power and torque and the car feels a lot smoother as well. Red Line is supposed to be a very good oil, if not the best and many people who use it brag or notice how smooth their cars run with Red Line. Don't get me wrong the Red Line ran smooth in my car too but Royal Purple has given me a good balance of not only performance but also a quiet and smooth engine. Best of both worlds is what Royal Purple has given me. I am now a believer! Give it a try and hope your results are just as well as mine.
P.S. I also bought Royal Purple oil filter to go with the oil so I am running royally great products. Just go to Pepboys, if you have one and hold a royal purple oil filter, its the heaviest filter compared to the others that they sell there. I have seen the filter cut open and it has a 100% synthetic glass media that filters the finest of wear materials but doesn't restrict flow at the same time. Some filters will compromise oil flow for filtering efficiency and some do the opposite. Not Royal Purple or they claim that.
added 4 hp on the dyno with oil alone, idles smoother all around better performance and i think 5 more mpg awsome oil .
Wow, this really takes a long time, I order a product, it came with free shipping(great), it took 14 days to get to my (area),next stop would have been at my door, it never made it that far. It seems the shipment was damaged in transit, so I followed it for 7 more days to return to (where it was shipped from)then waited 5 more days for a refund? If I had wanted a refund I would not have ordered the product in the first place. The solution to this case would have been to reship expidite (overnight) the item I wanted from the time you new it was damaged. I still want this item, but I will not wait the periods of time these transactions seem to take, we are in the computor age, correct? There is nothing at all wrong with the item, just the service part of this organization. Dennis C. Harrington
