Hello I' am the owner operator of a 2005 Mack granite tri axle dump. It has a AI-375 engine with an allison 6spd auto. This truck drinks diesel like theres no tommorow. I work with a broker in my area primarily and get paid by the load so I really can't be soft on the pedal but I don't abuse the pedal to much. I really just do the speed limit but the speed limit in my area is 70mph on many of the big highways. Also the distances im driving are are about 110-15miles round trip for 1 load. So im in the process of getting aluminum wheels all around for the truck maybe an aluminum bed but thats years down the road and I need help now. I have recently been looking at maybe a propane injection system when I noticed a Hydrogen Fuel Injection system made in canada. http://www.chechfi.ca/
But I don't know to much about the HFI system to justify if its worth the cost. So does anybody out there have any other suggestions that might help me out....
