LOL, Amzoil is good as is Redline and Royal Purple, I've used to use standard Valvoline and then switched to Valvoline full synthetic and now in two of my trucks I run Valvoline Max, I did switch from the Valvoline full Syn 5w-40 to the Rotella 5w-40 full synthestic in my diesel though. The Valvoline is over 30.00 a gallon and the Rotella is about 22.00 and when I have to buy 4 gallons at a time it adds up fast. I still change my diesel at 5000 and my gas rigs at 3000 regardless of what I'm using though. 22yrs in the shop have taught me you can't have oil that's too clean.

Sorry for the Hijack didn't mean too but it is funny how one thing leads to another.

I won't be wronged. I won't be insulted. I won't be laid a-hand on. I don't do these things to other people, and I require the same from them. John Wayne-The Shootist
