what are the difference?? PROS/CONS?

Don't know what the difference is.


I have used the powerservice since new with no problems-3800 miles. I also used it in my 02 powerstroke 35000 miles.


A buddy of mine has 2 03 LB7's one with 28000 miles and one with 55000 miles and has always used powerservice with no problems.


We use powerservice just because it is easier to find (wal-mart, autozone, tractor supply)

that is why I was asking.. power service is easy to find. Thanks for the info.
