    Fine oil. If you're going extended miles, just change the oil filter every 5K miles and top off the oil level.

    If your using the EAO64 oil filter from Amsoil, you just need to change it at 25k or 1 year, just like the oil. Its all my 2003 Chevy Z71 has ever seen and my 2007 Tahoe 5.3. In my Tahoe, I put 15k in 1 year and sent the oil sample off to lab. They said it had over half the life still left on it. My only concern for you would be mileage? In a 13 year old truck, if you had over 100k miles, did you flush engine first when switching from petroleum to a synthetic.

    I don't believe in the stuff. Seen way to many motors go for a lot of miles on regular dino oil. I just replaced the head gaskets on an 02 7.3 Powerstroke that has been running on recycled 15-40 for 260,000 miles and the cylinders were still clean and had the original machine marks. Was of money IMO.

    Okay, how about a Triton 5.4 with over 400,000 miles on it? I have not seen the inside of this engine so I didn't use it for the example. I have a folder on it in my files. Dino oil every 5000 miles.
