Royal Purple ROY01021 XPR 5W30 Racing Oil, 1 Quart

WoW!!! WoW!!! I put this in my 2017 F150 Raptor, it had just over 4k miles on it. and according to on board computer, I was steady and getting 14.8mpg. Now my driving habits had not changed and stilling going about the same routes, and locations, but I did noticed the mpg went up to 15.2 after 1k miles, and now at 6200mi, it's saying that I'm getting 15.5mpg.. that's an unbelievable improvement in mpg. On a separate note, my mechanic told me the Truck sound smoother instantly after the oil change, I thought it was psychosomatic, but apparent it's not. It is running smoother, otherwise, how did I get 15.5mpg? p.s. I'm a long time believer of ProLong full synthetic oil, and been adding that to my cars since the 80's, was kinda disappointed with ProLong being out of business, and had been using Mobil1 since. Ahhh just in case if you wonder, the truck had probably some cheap Ford OEM stock synthetic oil or blend when it was delivered.

Works great. Think they could come down on price a bit tho as this is almost double the price of most there other oils. But I love it. I use alot of there products an haven't been let down by one yet.

I use this in the manual transmission in my Honda vehicles. I changed it about every 35k and it's still purple. Never had an issue will continue to use this as long as it's available. Also use Royal purple products in my engines.

I am pushing 400 WHP (horsepower at all four wheels, not at the crankshaft horsepower, which is the usual rating), from a turbocharged 2.5 liter engine, on road racing courses, with sustained high RPMs for 20 minutes periods. In one day that is like driving 80 miles while you brutalize your engine for all it's worth. In approximately twenty such days I have never had an oil related failure. This is not your everyday oil for your daily driver. It is a low viscosity range oil for a high pressure, high performance, high temperature engine. Keep that in mind. It is not cheap, so there are better, more cost effective synthetic oil options for a street car.

I only use Royal Purple in my Vehicles. But to get it here to Hawaii it seemed like I could only purchase so much and then if I added more to my cart it wouldn't ship.

This is the second time I am buying this and my first use of this product was an amazing experience. Aceeleration is quick and my engine builder hasn't seen any difference or damage in the pistons, rods or crankshaft since the first day he built the motor, in other words, the motor is in the same condition as it was when new. I strongly recommend that you use the Royal Purple Oil filter. I think you can go 4,000 to 5,000 miles safely on this, more than that you are putting yourself at risk, but you can definately go more than 3,000 miles. For best results, buy a Oil Cooler with a small electric Fan mounted on it and run an extra quart of this oil and use a Magnetic Oil Drain Plug to protect from metal shavings in the oil pan.

This oil has a very high tbn and is rich in anti-wear ingredients. My cars run smoother and get better mileage with this stuff. Redline is a oil good too, however, customer service sucks there. Rp customer service and tech support is much better. Not to be confused with over the shelf rp at pep boys. This is a different oil.
