Fuel Filter/Diff Fluid

[stickk]

What brand of OEM style fuel filters are you fellas running? Just picked up a new to me '01 and I want the fluids and filters changed asap. Also wondering if the Mobil 1 75/90 LS is correct for the diff's.

I use a WIX or motorcraft filter for the fuel, and 75/90 is fine for the front diff. the rear diff is 75/140 WITH THE ADDITION of the friction modifier for the limited slip. OR a 75/140 limited slip fluid such as royal purple/mobil 1

I use Baldwin filters anywhere I can.
Oil - 15W40 is fine. 5W40 is best if you can afford it every 5-6.5k miles.
Oil Filter - Baldwin
Fuel filter - Baldwin
Fuel - I've done good on Murphy and Kroger here.
Trans - I flushed mine for the first time at 300k miles. It ran a bit cooler (auto of course). DexIII/Mercon.
Trans filter - I added an external spin on. Dieselsite type, I made it. Baldwin filter.
Coolant - I used Final Charge Global with a CAT EC-1 rating ELC type coolant.
Coolant filter - Like a Dieselsite, I made it. Baldwin filter.
Powersteering fluid - Flushed with Mobil 1 ATF.
Powersteering filter - added a Magnefine filter.
Air filter - I use a Baldwin PA2818.
Differential - My D80 LS took 8oz of limited slip modifier and the rest in Schaeffer's 75W140.
Your owners manual will say what fluids to use in the transfer case and front diff.

Well that about covers it for fluids. For fuel filters I prefer Donaldson, fleetguard and Baldwin fuel filters, all are at least 10 micron (factory spec) and strips water at a 93-96% clip.
