Answer to: average mileage increase for installI just got my fleet air filter and installed it today. I haul trash, dedicated run, 2 trips a day for 410 miles a day. Most loads are between 70k and 80k. My set up is a freightliner Columbia day cab with a Detroit 12.7 L 455hp engine and 3:55 rears. I drive 55mph on the freeway, and 1/4 of my miles are in the city ( about 50 total stop lights in a day). My trailers are open topped and I'm empty half of the day. I had been averaging 6mpg 68 gallons per day. Today on fill up it only took 59 gallons 7.1 mpg! Needless to say i was estatic! I have no other mods on the truck I know it was only one day but I'll be more than happy to keep everyone in the loop!
