32 miles per 4 gallons = 32/4 miles per 4/4 gallons = 8 miles per 1 gallon = 8/2 miles per 1/2 gallon = 4 miles per 1/2 gallon

I have a 1998 Disco I, using gas, not diesel, and I get about 14-15 mpg. About 350 miles on a full tank, generally all highway, it is hard to say if it would drop much if you did a lot of stop-and-go driving.
