Hey DOC my daily driver is a 89 dodge 250 ram with the cummins diesel first year in a dodge pickup and also a 96 1500 ram and neither gets me an award for fuel ussage as i spend about 145.00 a week in the cummins and the 1500 gets really lousy millage but the cummins is alot better on fuel but the 4.89 a gallon makes me sick to the bones
