5w20 and either 5 or 6 qts. Mine takes 6 but there is an ongoing controversy on how many qts.... To be safe go with 5, let it settle and see where it is on the dipstick if you need another qt then throw it in.

Synthetic Oil

I use Mobil One in all my vehicles. I've seen Mercedes that use this oil torn down after 250,000 miles with virtually zero wear (the car in question blew a head gasket after the operator failed to replace a radiator hose that, believe it or not, appeared to be the original item). The one thing they had done was change the oil every 15,000 miles (this is the recommended interval for Mercedes not operating in a desert climate - I'd change this to 12,000 then).

The oil is pricey, but as you can see, you'll be running it a lot longer.

5W-30 is the recommended oil weight. It takes 6 quarts including the filter. Ford didn't start recommending 5W-20 until 2001.

The engine never changed the only reason they started recommending 5w20 is b/c it gets slightly better mpg and the thinner oil can get up to the heads quicker on start up. So 5w20 or 5w30 is fine. Personally i just went with 6 qts. of 5w30 royal purple, and a k&n oil filter. Costs a little more but I have the money to spend on it so i went with that. A cheaper synthetic should be fine also. However, i would recommend a better filter than fram, i recently read a bunch of stuff bashing fram. Most people recommend motorcraft (purolator), or k&n.

Actually, my daughter's '00 GT has a factory installed sticker under the hood, and a factory manual that specifies 5W30....5 quarts, including filter change.

Always put in the minimum anticipated oil, then wait for it to drip to the pan.....and check the factory dip stick. NEVER overfill a crankcase, and NEVER change the oil without also changing the filter.

Send me an email and I will send you a Ford website that will enable any Ford owner to download an owner's manual and a service manual.

The oil cap on my 00 GT vert says "5W-20". I've always but 5W-20 in it since I started doing the changes myself.....

Went to dealer for oil changes every 3500 miles the first 3 years. Last time they put 6 qts in when the manual says 5. Dipstick was way over FULL mark. I took the car back and showed the guy where the manual said 5 qts, he said the updates shop papers show the engine should have six. I told him to take the car around and drain a quart, as my rear main seal was blown out of my old vehicle from a shop putting an extra qt in. He said it wasn't necessary, and I told him it was MY car and I said to take the oil out, which they did. Never did take the car back to that dealership again.

Now I put 5 qts 5W-20 Motorcraft synthetic blend oil in. Costs about 1.62$/qt at walmart.
