Tips on getting the best fuel economy or mileage.
#12
squirrel, that is also true with passenger vehicles. I ran an average of 86mph on a run down I-81 from 300 miles(thank god no cops were out that day.) Turned around and ran 70 mph back, got better mileage at 86 in my pickup. The engine's tuning was for max mileage at a higher RPM. Did not know that until my dad showed me. My wife's Fusion is the same way. Got better mileage going to Greensboro averaging 68 than averaging 62 coming back.

The result was he got BETTER fuel mileage at 68 in HIS truck due to the way it was set up.

well for one thing if your hauling flatbed as i do then loads that are lowest to trailer floor will get 1-2 more miles per gallon than a load that is 10 ft high. i get 7.5 8.6 mpg when hauling skid coils from indy in area to g.r. mi & back at 62 mph on cruise. doing the same run at top end i'll get 5.5-6 m.p.g. i also exccelerate slowly from a stop.

We had a great topic on this a few months ago, 3 pages long. It even has some good information in it.
