What to start with first for better fuel mileage?
I survived my first year as a lease operator and now after finding this site and radio show I am trying to increase my profits.
I was at about 5.5 mpg last year driving at 69/70 mph with 40k to 78k vehicle gross weight in a dry van trailer with side skirts.
Since last week I droped to 60 mph and am now averaging around 7.3 mpg.
I have put a freeze plug in the egr cross over tube. And I just put on all new tires diamondback RT697...(yah wish I had found this site before buying them)
What are the biggest mpg items I can add first?
ECM tune (egr delete, mpg upgrade, horsepower)
free flow muffler system
I hear kevin talking about direct drive can I do that with 10spd with 3.58 gears? Isnt that like 9th gear at 50mph? Can i change the gears or would i have to change the whole transmission. is it even worth the mpg gain to do that?
Thanks for any help.. my goal is to hit 8.5 mph by the end of the year.
Is this a worthwhile discussion?
