Max Mileage Fuel Borne Catalyst is a liquid fuel additive that directly improves your engine’s combustion and efficiency.

Increase thermal efficiency 

Accelerates the burn rate of diesel so more BTUs of heat are released earlier during the power stroke instead of being wasted as soot and high EGT. Diesel fuel molecules vary in shape and size, and this allows the all of them to burn faster increasing thermal efficiency by 10% 

Burn soot at a lower temperature

Once in the exhaust system, the catalyst continues working by burning soot at a much lower temperature, 750 degrees Fahrenheit compared to 1000 degrees (the normal ignition temperature for soot).

Keep Injectors Clean 

The proprietary formula is supplemented with a fuel injector cleaner that removes fuel injector coking deposits and prevent new deposits from forming. This is critical to maintaining factory-rated fuel economy by ensuring optimal fuel “atomization” and fuel injector spray patterns into the cylinder.


Decrease soot emissions by 60%

Say goodbye to soot related "check engine lights." Stop replacing EGR coolers, EGR valves, DPFs, and maintain them with Max Mileage. If you have a 2007 and newer truck, you can keep your truck legal without sacrificing reliability. 

Reduce DEF Consumption

With less soot, less DEF (Diesel Exhaust Fluid) is used. Here's where the product more than pays for itself.   

Longer Diesel Particulate Filter Life

Less soot also means your DPF will last much longer without any maintenance saving you time and money. 

Fewer active regens

Wasting fuel on forced regens is not productive to your business. With Max Mileage you may notice fewer regens. 

Increase fuel mileage 3% to 10%

Results may vary, but typically after the first few weeks many notice an improvement in fuel mileage due to the more efficient combustion. 

Extends engine life 

Soot is the enemy of any diesel engine. It's abrasive and harmful to your engine's rings and liners. Max Mileage will lower the soot levels in your oil sample. 

Smoother & quieter engine

Often the first and most noticeable change. You may feel more power, response, and a much quieter and smoother running engine. 

Lower Exhaust Gas Temperature 

Increase the life of your turbo, manifold, and exhaust system with lower EGTs. 

More Information

Made in the USA 

Max Mileage is formulated in a laboratory in Texas and then shipped to Pittsburgh Power where it is bottled. 

Lab Tested and Field Proven

Developed and tested specifically to provide the maximum benefit to the owner operator, we then spent months road testing to ensure you will see real world benefits. 

EPA Registered 

EPA registered as "288920002 Max Mileage Fuel Borne Catalyst"  under EPA law 40 CFR 79.23

Highly Concentrated

1 gallon treats 3200 gallons of diesel. Each ounce treats 25 gallons of diesel. It's formulated to mix in fuel tank very quickly and efficiently.

More than Pays for Itself

Other than the obvious savings in DEF fluid and diesel, you will also see savings from a less frequent check engine lights and emissions system repairs. 

Use for Diesel and Gas

Safe to use with any diesel engine, old or new. You can even use it for a gasoline engine. For gasoline use, change the ratio to one ounce for every 30 gallons. 


  • Q: Can I use it for my diesel pickup truck, VW TDI, farm tractor? 

    A: Yes, it can be used for any diesel engine. 

  • Q: Can I use it for my gas engine?

    A: Yes, it has anti-knock properties so it works well for classic cars. 

    But please change the ratio to 1 ounce for every 30 gallons. 

  • Q: Do you have a Canadian distributor?
    A: Yes, please check the map below for contact information.
