3 quarts of 75w-140 synthetic for stock cover, 5 quarts for mag-hytec cover. I always buy one extra quart just in case. If you have stock cover need new silicone to seal it back up as well.

Hey Pirate, I got the canister purge valve on the engine ticking loudly, no Check Eng. light. Should I get a new one or just wait til it throws a light? Ford parts wants $60 for a new one.

Just switch it out. Online Ford OEM is $20 IIRC. I have a spare that I will sell you for what I paid for it

Hey, don't our differentials require some kind of special additive? Something about their limited slip design, if I remember right.
are you still there? if you wait there a little longer, a few more people might chime in.......

Sorry I was off with the price (bought this almost a year ago). But here's the cheapest $36 if you have Amazon prime: Amazon.com: Motorcraft CX-2369 Fuel Injection Auxiliary Valve: Automotive
I paid roughly $40 for mine

This is what the owner's manual says about the front diff: 1.8L of Motorcraft SAE 80W-90
Premium Rear Axle Lubricant
and for the rear diff: 2.6L of Motorcraft SAE 75W-140
Rear Synthetic Axle

Russ, I don't think we have LS diffs?
