You need to ask before you keep buying buy parts ,, The OEM filter is a Donaldson and is good well past 60k in some cases ,, you also should have a filter minder to look at and verify condition ,, take the FRAM back and get an oem $100 or look at dieselfiltersonline.com

ill definitely look into that

Yeah I'd stick with stock motorcraft filters too. They don't need to be replaced very often, they will hold a LOT of dirt.

When checking your mileage, as you're filling your tank you need to keep filling until you see fuel in the filler neck and it stays there. Usually when the pump clicks off on these trucks, you can fit another 2-5 gallons of fuel in there. Fill it til it clicks, then slowly keep adding more and more until you have fuel right up to the neck. It takes probably an extra 10-15 minutes after the pump clicks off to do this right. If not, you have no idea how many gallons you actually used, they click off at different settings all the time. The reason being the way the fuel foams and how the fill lines go down into the tank. There is a mod to fix this, but requires dropping the tank. Search Harpoon mod.

i replaced the air filter and filled the tank to the rim and is looking good.
i have driven almost 90 miles and the needle still in full.
before 90 miles and it was down to half tank. im happy as pig in sh-t.
im going to drive till is half a tank and then ck for mpg
thanks everybody. ill keep you guys posted.

Yes, mine usually goes about 75-80 before needle moves off of FULL after a "REAL FILL-UP". It's just such a PITA to fill it that way all the time.

mine goes like 200 miles before the needle moves :choochoo:

i have driven a little over 100 and the niddle has not move:jump:
last time 100 was half a tank
