Chaning Differental oil ???
Have an 03 F350, 90K miles, how often should the diff. oil be changed ? Ford lists the oil that came with is as synthetic. We do about 1/3 towing and the rest around town. Thanks

Read the manual for sure. It's probably either 50,000 miles or 100,000 miles depending on use. Towing and running around town are both hard on it. Long highway trips not towing would be easy life on the oil.
I'd change it.
