2002 KW 6NZ Cat
Last month (July 2020), I got an increase of about 18% but that can be due to tailwinds, light loads, or a multitude of things, but since I keep good track of my mileage and like to average it over a six month period or so, I’ll let you know in December just how much it has changed. So far, I’m impressed.

1986 359 Pete with 1994 3406C Mechanical Cat
I usually drive about 125,000 miles annually and use about 29,761 gallons of fuel. After the AirDog was installed, my fuel use dropped to 24,038 gallons! My mpg pulling my Bull Rack before putting the AirDog on was 4.1-4.3, now I get 5.2 and have seen up to 5.7 with no wind and 70-75,000 lbs. Plus, my manifold pressure went from 27 to 33 psi and my exhaust temps dropped from 825 down to 650. The truck puts out less smoke and idles much smoother.
We have been taking my Cat to the dealer for years on a running issue and that entire time no one could fix it. Immediately after (the AirDog) installation, the motor idled better and was more responsive. The very first run I gained .8 mpg and the power gained was amazing. Plus the problem I put up with for years was cured! Everyone needs to know about this product.
After some time of use, we noticed a loud growling sound that we thought was coming from the (AirDog) unit. We were advised to bypass the AirDog, then send it in for warranty. Immediately after removing it, we found out it was not the AirDog, but our factory Cat transfer pump that quit. Thank you AirDog for getting me home.

With the AirDog installed, the results in fuel savings are 10.70%. The driver stated the truck is quieter, starts easier, runs smoother and has more power. His quote, “it makes pulling a heavy load feel like a light load.”
Cat C15 Acert
I pull big heavy loads, up to 120,000 pounds, with my C15 Acert. Before AirDog, I was getting 2.3 MPG. With my new AirDog, I’m getting 5.5 MPG loaded heavy and 6.5+ MPG on (80,000 lb) light load. I drive easy, but AirDog has still done wonders for power and fuel economy for my Cat.
After installing the AirDog on my C15, the last 7,022 mile trip was an average of 6.02 and I have seen 7.34 on a 3,601 mile run. Sometimes I think I should stop and pull the hood to see if it is really a Cat Bridge Engine in my KW! The performance and ease is very impressive when pulling the hills.
