My Diesel when not towing gets about 20 -22 mpg but it is the smaller Diesel from 2003, the diesels now are bigger so do not get the mileage we get AND a new diesel now requires an extra fluid that must be added every so many miles. Do not know the name of that fluid, it is something the diesel stations have available as I understand it but.. I was told I should upgrade the brakes to a heavy duty break that cools faster and get some stronger shocks but I love my 2003 Duramax Silverado 2500HD
