Great oil. Had sluge and dealer says new engine. Hmmm. Found out this oil will dissolve sluge. Used it removed the valve covers and sluge is gone. Increased my gas mileage also. Good stuff

Rated 5 out of 5 by fxer great product
I have been using this since my first oil change. I changed oil at 7500 Mi. as recommended by Kia. Since my warranty has expired, I now change oil at 12000 mi> like Royal Purple says I can. I have driven more than 150000 trouble free miles. I am looking for Royal Purple to make a high millage version of the 5W20 oil that I use. I am usually able to buy this when pep boys has a special promotion.

Rated 5 out of 5 by BuggsinAZ The ONLY oil to use!!!
I drive a high performance Mustang GT. Royal Purple has been outstanding under some grueling driving experiences. It's the only oil to use in a High Performance car. PS: I also use it in my 2016 Ford Escape 1.6L Eco-Boost!!!

Royal Purple is the best synthetic oil ever. I have used this oil in my 07 Toyota Tundra since the first oil change. I get better fuel economy, once a year oil change. Saves fuel, save the planet,No oil! I have installed the synthetic in both my differentials. I swear!

I've been using Royal Purple for the last seven years in all my cars. Although this is a 15,000 mile oil, I do change the oil every 7,500 miles due to heat and stop and go driving. The oil has never let me down. My car is rated at 23 MPG Highway, but with this oil I an consistantly getting 25+ MPG of regular gasoline.
