It's Royal Purple!, May 9, 2010

I have a '09 Ford F150 Platinum. 5.4L V8... Royal Purple gave me better gas mileage by 1.6 MPG. I used a performance K&N Oil Filter (Wrench on) and the royal purple. It's amazing. I believe 100% in this product.

I used this oil and the matching royal purple filter for the first two oil changes on my brand new 2012 Ford Fusion Sport AWD. I shortened the first two intervals to about 4,000 miles to get the initial break in materials out of the engine and then had each oil sample analyzed by Blackstone Laboratories. The Results were perfect! The oil had tons of life left in it and could have definitely met\surpassed the factory 10,000 mile recommendation while providing my engine with maximum protection.

Good price, not the best, but I love doing my business with Amazon and its merchants. When it comes to oil everyone has their favorite, Royal Purple is tried and true, it has yet to let me down. Will buy again, also it came well packaged and in air tight bags.
