Re: How many quarts?
I changed tranny and rear end oil to synthetic at 20K ( and 4 years) - a little insurance policy maybe. Gear shift MUCH improved. No idea if rear end better/worse.
As for engine oil - whatever synthetic they (Ford, Jiffy Lube etc) put in to hit the mid mark on dipstick. I'm not that fussy, synthetic oil is good no matter the brand and I'm relatively gentle on the gas.
