Our History

Fuel Mileage Dr. and it's beginnning

Bully Dog - FMD - Logo


Fuel Mileage Dr. has been a Bully Dog dealer since January 2013. Fuel Mileage Tracking has been part of the owner of Fuel Mileage Doctor's career the last 15yrs and he says "Selling Bully Dog MPG and Performance Products today only makes sense."

Bully Dog Tuners work on Cummins, Paccar, Detroit, and Cat. We see gains of 6 to 10% consistently and in Heavy Haul applications as high as 18%.


Fuel Mileage Doctor New Logo Primary

Kevin (the owner of Fuel Mileage Doctor) started out as a mechanic 35 yrs ago. He worked with small fleets and was a service manager for a 250 truck fleet 10 years ago in charge of tracking MPG. He also worked at an OEM engine manufacturer as his latest career before starting Fuel Mileage Dr.

FMD is a mobile business, we come to you – or will ship to you. We have parts in stock on road service vehicles at 2 Locations – Eldred, Pa. and Mifflintown, Pa. If you purchase any of our products from us, we offer a FREE complimentary installation if you are anywhere in Pennsylvania or close enough for us to drive to.

Kevin will gladly meet an owner or operator at a truck stop or anywhere in Pennsylvania to do an install of a tuner which takes only about 1 hr. We will come to fleets as well. We offer onsite consulting for M.P.G. Companies want to save on fuel but you would be surprised at how many do not know their exact fuel usage. Thats where Kevin's past history will help you out. We have software to download engine ECM’s for current fuel mileage but the best way is miles vs. gallons.

White Oak Mills Makes Gains in Fuel Economy with Bully Dog - Movin' Out

White Oak Mills Transportation Installs Bully Dog With Fuel Mileage Doctor
"...White Oak Mills Transportation Manager Josh Long was searching for a solution when he spoke to his friend Charlie at Wolf Pack Transport. Charlie recommended that Josh try Bully Dog as the entire Wolf Pack fleet is equipped with Bully Dog. Bully Dog representative Kevin Campbell allowed Josh to try a unit on 2 tractors, and the results were an immediate 7/10 mpg gain. The White Oak Mills fleet is currently running 10 Bully Dog units, going from a 4.5 mpg to 5.2 average, including off-loading at high idle. They will save an estimated $50,000 in fuel costs this year and Josh is happy at finding a solution to his fuel economy dilemma..."
