    Looked pretty nasty IMO, 238k on the truck, bought it in July 2019 with 232k and noticed my mileage was nowhere near what PO said (18mpg) I was getting 12-15... so changed this bad boy out the other day. Planning to make this a 10k every other oil change maintenance item.

    @Dieselcrawler that's the Travelall in the background, I'll be back with some real progress haha getting all the sheet metal work done now, probably 2 or 3 more weeks until she's ready for primer.

    That's not a factory style filter is it?

    My question on fuel is this, you running straight diesel or a bio-blend? Back when mine was a daily driver running the cruise at 62 I got 21.X on straight diesel. B20 dropped it to 17.8. Mostly freeway driving, acceleration like grandpa.

    Im running straight diesel and I flip flop between power service diesel Kleen and Howie's meaner kleaner until I'm out of both (soon) then switching to diesel extreme. That is the factory cartridge style filter for 97-98. Mine is 4x4 and auto if that helps for comparison.

    Also 80% street driving for me, 3.54 gears and I like to get upto 50 quick and just light on the throttle at that point.
