There is a noticeable difference on acceleration and especially when driving on the open road. Highway driving was getting 19 mpg. Now with the AirDog, it’s getting 23 mpg.

Our utility truck was at best making it through the workday; we were looking for something to help with low power. After the installation of the AirDog, we found an enormous gain in power and I can’t stop grinning every time I drive it. You may not need this kind of power to get from one job to the next when cutting grass, but you do need it when delivering heavy loads over hilly streets and highways to customers. AirDog gives you the power to get there on schedule and reduce fuel costs at the same time!

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.

1997 Detroit Series 60

I have a 1997 Series 60 Detroit that was getting only 5.5 mpg. After installing the AirDog, my fuel mileage increased to an unbelievable 7.1 mpg! I would recommend the AirDog to everyone!

Directly after installation, the typical gains were not as noticeable. The team drivers left for California from Oklahoma City with a prior average fuel mileage of 6.8. After returning from CA, the new average was 7.8 – a new all-time high for this rig! We are also monitoring the DPF Regeneration and will have additional factual data in lowering the amount of cycles needed.

After updating to the 4G HD AirDog, I picked up an additional .5 mpg over the original increases. We are truly impressed with the product and telling everyone about it.

500 Detroit Series 60

We installed the AirDog fuel air separation unit on our customer’s 500 Detroit 60 series. We had previously installed a K&N filter, Bully dog heavy duty gauge tuner and a Bully dog exhaust manifold, which brought the customer’s fuel mileage from 5.4 up to 6.2 mpg and overall horsepower up to 550 and 1811 fp of torque. Once making a run on our chassis dyno, we quickly realized how much was gained by installing the AirDog system. HP went to 569 and torque jumped to a staggering 1888 fp. The customer then left out on his first run of 3,000 miles just to return and report even more gains regarding the fuel mileage. It now sits at 6.7 mpg, so overall gains after the installation were 19 hp, 77 ft/pds torque and .5 mpg fuel mileage improvement.

2010 Cummins ISX 550 HP

The last three years of operating my 2010 550 hp ISX with a FASS, my average economy was 7.2. I was hoping to have some fuel increase from switching to the AirDog, but couldn’t imagine the actual gains I was going to receive. My fuel economy with the AirDog has jumped to 8.5-9.1, plus the filter monitor separator. Way to go AirDog!
