Thank you for your AirDog installation (installed by dealer, Michigan MD Alignment). My truck runs SILKY SMOOTH. Is the most fuel efficient truck in its class. Thanks again. Paul Mausolf

2013 Paccar MX Before AirDog, there was constant reoccurring engine codes, fuel de-rating and low power. After the installation of the AirDog, none of these problems have reoccurred. The engine regained the power it was designed to have and picked up .2 to .3 mpg. Plus, it has completely eliminated any air locking during filter changes and has over 35,000 miles on the fuel filter. Dennis B. Sioux Falls, SD

I first heard about the AirDog line of products on the XM Radio Road Dog Trucking show and purchased an AirDog in February 2021. I have noticed an improvement in throttle response and a lot smoother engine idle. I have also noticed an increase in fuel mileage, which I track using Kevin Rutherford's fuel gauges.

I have seen great fuel mileage improvements as my prior average fuel consumption was in the mid 6’s. My last two tanks were 7.2 and 7.9, which is the most I have ever gotten! George Malone Transportation Dow City, IA
