| Richmond, Va. Diesel MPG loss ? I had breakfast today with 8 fellow Duramax owners. A problem was discussed that all of us had noticed ... in the last week or so, all of us have experienced a MPG loss of up to 4-5 MPG. Is anyone out there in the fuel business that can answer if maybe some change has been made with the fuel in our area ? Or is anybody out there in my area ( Richmond, Chesterfield ) noticing this too ? I thought I was alone until this morning. |
