    15,000 miles

    I use Mobile 1 and change oil, fuel filters & roate tires every 15,000 miles. I use to do every 10,000 but I think the oil is holding up ok at 15,000.

    I put FASS fuel systems on all of my diesel trucks. There are open fuel filter deletes available. Higher micro filtration better water separation and fuel pressures FASS states 25k I typ hit 15-18k Rotating tires at 5-6k. At 15k I would have to run to 20-25 and just by 2 new ones w/o wt rear tires get most wear from torque.

    If you take 15,000 miles and divide by 60 mph you get 250 hours.
    On all our work pick ups and semis we change at 15,000 miles.
    On all our equipment we change at 250 hours.
    We change engine oil and both oil and fuel filters at those intervals.

    20-30k and the first stage filter still looks like new.
