Happy

I have used this product for several years now and am very pleased with it's performance. I had been using another high quality synthetic motor oil for a long time and while it worked well Royal Purple exceeds it. With Royal Purple the diesel engine in my 2001 Ford runs quieter and usage is practically zero. What got me to first try Royal Purple was the price from Walmart but I'm sold on it now no matter the price. I'm just now switching over to their Max Tane injector cleaner.
