at 1mpg improvement it would take 150 tanks to break even, which is about 4 years at 12,000 miles a year. at 10mpg improvement assuming the front is the same price, or $500 total, it would take 30 tanks, less than 1 year to break even. Probably worth it either way unless you plan to sell sooner than that.
