Max Mileage Fuel Catalyst

We’ve been extremely satisfied with the fuel born catalyst

It adds great fuel mileage

i’ve been using it for a year now, much cleaner exhaust stacks and not near the black pieces of debris when it starts in the mornings.

I have a million plus mile truck. Last year I started replacing all of my DEF system sensors, doser,filter,you name it. Could not get any relief from constant Parked Regen on my dash until I started using Max Mileage. It took awhile but WORTH IT. I've been using this product for about 4-5 months and I'm getting very good results. No more dash lights flashing. I'm a happy customer !!!!!

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.

Our Driver review - Soot level is staying under 30%. Truck not throwing after treatment codes. Impressed !

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

Very good cold weather proctor

Winterized max works great best additive available the issue I have with you is twice y’all reset the valve lash on my DD 15 and I had to take it to freightliner to have it fixed .I will continue to use your products but you folks will not be getting my business unless it is emsions related. I operate modern efficient equipment

The product performs exactly as expected. Good product. I really miss being able to have it on subscription as I did last winter. I also wish it could be purchased in 5 gallon pails to save on individual shipping costs.

Best anti gel ever

I run the max mileage already haven’t used the winter mix yet . But do have a question do I run both of them at the same time in the winter ? Or just the winter mix ?

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.

Have been wanting to try it based on reviews. Put some in my pickup and in my wife’s Prius without her knowing. She asked me what I did to it because it seems to have more power. I noticed a difference in my pickup truck also.

The first time I used it in my truck, I smelled it working as the truck was running. The best thing about this product is
that there are less regens and better fuel mileage.

16oz Max Mileage - Fuel Borne Catalyst - Two Pack

My o2 sensor was making my check engine light come on. I put the catalyst in and within a 1/8 of a tank of gas the light went off and has been off for 2 plus weeks now.

A person can see a difference in power, gas mileage, and sometimes can smell the solution working.

Truck purs like a kitten she is definitely loving it. Highly recommend your additive! Better mileage and a noticeable boost in power.

will work fine on first gallon. will not seal on 2nd gallon

Leaks

O-ring inside dispenser tap Swells comes dislodged and links, because it’s made out of rubber not 100% silicone rubber, Very poorly made product not worth buying

i like it but it has a regular round oring and leaks a little needs a flat oring like a garden hose uses...i am going to try to find one or make one then it will be perfect...hope this helps

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

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

8oz Measuring Cup for Max Mileage

Great stuff. Will be ordering more.

Measuring Syringe for Max Mileage

I don’t know how long the rubber part of the unit will last but for now it’s holding up I use it to measure out small amount of max mileage for my gas powered equipment as mowers, snowblower and motorcycles and ATV
