This summer I am gettin an 88 full size 4X4 bronco and was wondering what all could be done to it to get better fuel mileage. I haven't driven it and am not sure what kind of fuel mileage it gets, but any help would be awesome.

 

Properly sized tires, a good tune-up including a good air cleaner filter, and driving a few mph slower help a bit.

I am guessing it is a 302 or 351 and will get about 12-14mph.
