I bought a 2015 Freightliner with a DD-15 that had approximately 2500 miles on a new one-box. I personally drove the truck 400 miles to the nearest Max Mileage Fuel Catalyst dealer. I added the Catalyst and in less than a mile the truck smoothed out, ran quieter, and had almost “throw you back in the seat power” (bobtail). Almost 40,000 miles later I haven’t had one regen yet. Zero emissions problems. I am hitting 8 mpg, with a drivetrain that doesn’t have exactly the best specs. 10 speed trans., 3.25 rears, no cab fairings and nothing else to improve aerodynamics. I have used the Max Mileage Fuel Catalyst in all of my engines. Everything from my F-150 ( another two MPG), to my lawnmower that was almost on its way to the landfill when I added the Catalyst, now it’s like I installed a brand new carburetor. I also secretly added it to my wife’s 2018 Mini Cooper, she knew instantly that something was different and she couldn’t believe that all I had done was add something to the fuel. I’m a true believer in Pittsburgh Power and the Max Mileage Fuel Catalyst. My truck will never go without it. It’s money well spent , I can’t afford the downtime , repairs, and all of the B.S. that goes along with emissions problems. Thank you Pittsburgh Power and Dr. Jane Gates.

Max Mileage - Fuel Borne Catalyst - 1 Gallon
Run it in my isx and my 1967 mopar it loves it. The lawn mower and my fairbanks hit and miss well all my engines
Definitely going to continue Running it!!!!
It has never been so easy to add something to the fuel as it is with the measuring bottle
Awesome
Very Handy and well designed at a reasonable price!
Love this spout! No waste!
Needs to hold little more capacity, needs to be at least 24oz
It’s best product since I have been using this my truck regen less engine runs smoother and mileage is increased
This Max Mileage is the best fuel additive,catalyst. I’ve tried everything out there in the last 30 years it smooths out every motor I’ve put it in. I run it in my 2018 Freightliner dd15 ,6.0 Powerstroke 7.3 Powerstroke my wife’s car, wildcat XX. haven’t tried it in my Yz 125 or Yz250. Also used it in my Onan generator as well as my predator generator I use on my semi truck for my APU. Everything runs smoothly and quite.
Great stuff been using it for 3 yrs and love it.
Used 8oz (160 gallons) for 8 fill ups did not see a decrease in def usage or better mpg 2023 dd15 auto casscadia
Also measuring cup came broken in 8 pieces i paid extra for was just thrown in box
I added this to my 2021 Ford diesel truck, it improved my fuel economy by 4 miles per gallon. i also noticed that my def gauge barely moved on my 750 mile trip. Thank you, i will keep using this.
I never get my cup or my measuring syringe
I have noticed that it has improved performance in the motor and my fuel mileage has improved too. The 8oz cup does help with putting the right amount in when you put fuel in the tanks.
This cup is better than the ones sold at the truck stop. Thought y’all changed cup

Great stuff. Will be ordering more.
