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

When I had my TT I changed the diff fluid every 25k miles. It was easy for me to do and sometimes I had access to the fluid. I also did my trans fluid as often. Same for brake fluid.
