I purchased a 2007 2500HDClasic LBZ engine.
My question is do you change the oil by following the computer intervals? Or is there a formula to follow?Same qustion with regards to the fuel filter?
welcome to the forum..well those are some good ?'s and one that gets lots of opinions so i'll give you mine..i would run the first couple thousand with the oem oil and then switch to fully synthectic oils and change every 5k to 8k depending how heavy you use the truck and on the fuel filter well keep it changed every 8k...
