I got GREAT gas mileage yesterday! I was towing around 3500 pounds with my '94 E150 and the 351 engine, for a long distance. I fueled up earlier in the day to see what my gas mileage would be. Then at the end of the day, I checked what my fuel mileage had been over that stretch. And I got 17 mpg! Later I pulled another load, this one about 2500 lbs. and got the same mileage. I am VERY happy considering all of the comments about Ford's getting bad mileage. I plan to keep the van for a while... Lord willing. i was going about 50-55 mph too. Has anyone else gotten good towing mileage from their truck?
