All I hear about semi trucks` fuel mileages is that they get 6 miles to the gallon. New semi trucks have innovations to make them more fuel efficient. Are there 18-wheelers that get 7 miles to the gallon yet?

• the largest myth of all trucking....buy a 500 hp engine and cut the fuel back on it w/the impression it will save fuel...hahaha. if the companies want to govern the trucks @ 68mph..fine.but they havent discovered after all these years,that everytime you cut the fuel back, you more you must downshift climbing a grade, you are DESTROYING your fuel mileage....(and the life of the engine)

• Do they have better acceleration? Do they carry a larger load?

• Loads are up from 76,000 to 80,000 lbs and rigs are lighter so we're slightly more efficient that way. Naturally 500 HP will accelerate faster & go over hills quicker than 220 HP. Roads are much better, I live in Canada but I will ONLY run South - never East/West in Canada. U.S. is much more truck friendly. Plus I like most Americans - great people & great roads.

• TED, you are another old school driver like me who cut his teeth on 2 sticks and a 238 detroit w/ brown tag injectors......(that was a big motor back then).
  youre right they got about the same mpg of todays trucks,back then at 30 cents a gallon we werent worried about fuel mileage.

• Thanks allikatzpop. If you want to see a puzzled look on a truck drivers face just tell him you were "GOOD ON THE STICKS" That'll do it every time. I still run from Vancouver BC to Salt Lake City - legal in 18 hours and enjoy every moment. I know Wash. Oregon, Idaho, Utah, Montana, Wyoming and Colorado like my own living
  room. Enjoyed your comment
