Last week I drove 803. 3 miles on a tank treated with Power Service Diesel Kleen and filled up on sunday with 38. 11 gallons(I think I pushed it a little too close to empty
)
calculated mileage 21. 078
computer readout 18. 8
The tank was probably 85% highway @65 mph and the remaining 15% was heavy city traffic. I did pull a 2100# flatbed trailer 50 miles empty, and an additional 25 miles with a Mazda 323 loaded.
HO, 6 speed,4x4, 3. 73, QC, long box
tires at 72 psi
