"Started using max mileage last Feb. I have a Maxforce 13. 430 horse with 800000 mls. It was regening every 500 mls. With a just cleaned DPF. After 3 doses of mf it went to 5000 mls. Between regens. I couldn't believe it.it is starting to regen more often now after many thousand miles but I think it may have filled the dpf with the crap it cleaned out of the engine. I never put a lot of stock in additives but this stuff is incredible. Thank you very much."

"2012 Dodge 3500 4x4 6.7 Cumins Diesel 232,000 +/- miles. This is a work truck, alway loaded, pulling lots of trailers too. Highway and rough dirt roads in New Mexico, Arizona, Colorado, Texas. Hot, dry, dusty or muddy. We have seen an increase in mileage by 15 to 20% by using the PPP Catalyst."

Chris Morrison


"Been buying max mileage from petro in Joplin Missouri. Been running it for about nine months and have noticed fewer regens, better mpgs this stuff works. I drive a 2015 Mack pinnacle chu with a 505 Mack mp8 13 speed and 336 rears.I run between Big Cabin Oklahoma and Austin Texas pulling a tanker. Just to try I have went without max mileage for a month and can tell a world of difference. The truck regens more fuel mileage dropped half a mile to the gallon and the truck just seems sluggish."

Roger Hummel


"I have used the product for a few years now in my 2006 Duramax LBZ pickup that I deliver Airstream camper trailers all over the country with. My truck now has over 900k miles on the original engine with the original turbo and still on the first set of replacement injectors. And still has the original EGR valve. I have used the catalyst for the last 600k miles along with power services fuel additive. So far so good, I will let you know when I hit a million miles."

Scott Buckendahl


"I use the catalyst in my 1999 Ford f150. Increased my mpg 2 to 3 mpg and makes engine run very smooth."

"My company truck is a 2012 Peterbilt 587 with a 2012 Cummins ISX15 on 440,000 total miles. I've only just begun using your catalyst for only 400 miles. In that time I've observed the engine run at both idle & highway speeds much quieter with greatly diminished vibration. At idle the pronounced "dancing" vibration by the tractor is gone. No noticeable mpg improvement yet, but I'm not expecting that. Happily, I'm surprised to have seen any improvement this soon. This catalyst works as advertised & I'm looking forward to the results after longer use."

Kevin Hannasch

"I have 60 series 14 liter Detroit and after I started using max milage when truck is idling how much smoother it ran and completely got rid of vibration in in cab. As far as milage, its hard to tell I run up in northern North Dakota and Minnesota I'm always fighting side winds 15 to 30 mph out of NW. When its calm I can get over 8 mpg."

Troy Morris

"Thank you! Max mileage works for my new truck, it had regen problems. After using a half gallon of max mileage and running three forced regens I have had no problems."

Bobby Long

"Just wanted to thank you for an Awesome product: Max Mileage!!! I have a 2011 Ram 2500 6.7 Cummins & have seen only a couple regens since starting to use this, I'm almost finished with my 1st gallon. I know several people using it & they have the same results.

Love you guys, keep doing what you're doing."

MJD Transfer

"I picked my truck up today and the mechanic asked me where I bought my fuel, so I said why, he said there's not a speck of carbon in that head or Pistons anywhere, it's really super clean. So I told him about the catalyst."

Chris Kyle

"I bought a 2019 Freightliner Cascadia with a DD15, DT12 direct drive, and 2.28 rears, assuming that it was spec’d well enough to run at 65 mph and not need to use the Max Mileage Fuel Bourne Catalyst and not have emissions system related problems. Under this assumption, I set out to run the truck for 30 days without using additives.

Scott Walker

“Several years ago I visited with Jane about your product - I know I'm only one of many people she visits with. At that time I didn't start using your product, the price per gallon stopped me. I drug my feet a couple of years. At that time I had just purchased a new Volvo truck with a D16 engine @ 600 hp & 2050 torque. At around 3 years & about 350000 miles I started to have problems with the sensors acting up with soot. About every 2 to 3 weeks it was happening - between down time & the cost to fix was getting expensive. At that time I started using your product, and from that point on my sensors gave me no more trouble. I also have a Carrier api unit on the truck so I did not have to idle at night or on the weekend. That also helps my sooting problem. I am very impressed with your product... I am now fully retired after around 51 years of driving. Thanks for a very good product."

Michael Wiser

“I received the Max Mileage Catalyst in today. I ordered from you guys late Friday after your email. It was a little delayed due to our snow storm Tuesday afternoon. I placed it in both my 2500hd chevy and my 2019 high-country. I am amazed how much smoother my vehicle runs with just one dose. My 2500hd has had a engine light on for weeks, I had it tested a few weeks ago and it showed a bad EVAP solenoid. I replaced the solenoid and it didn’t fix the issue, I than replaced the gas cap and still didn’t fix the issue. I placed the Catalyst in and fueled up, I drove several miles and was amazed, I got back to the house and turned vehicle off, I had to run down to the store, with I got back in and started the truck to my amazement the engine light was off. I am sold on this product. I cant wait to put it in my wife’s vehicle and see the difference. You guys keep up the good work."

"East Mead Twnship treats the 1000-gallon diesel fuel tankwith Max Mileage Fuel Borne Catalst. We are a small, rural township with 15 pieces of equipment in our fleet and treating the tank allows us to experience this products benefits in all of the equipment quickly and easily."

"Our 2010 Workstar international 7000 Maxxforce truck has made great improvements in performance since using this product. There is less cranking when starting and it has more power when operating with a load. Prior to using the MAx Mileage there was an engine warning light that was consistantly displayed but now that situation has been remedied with the use of this product."

The test engine: 2016 Cummins ISX CM2350 set at 550 hp. The fuel treatment began April 2018 with 272,476 miles on the odometer and concluded in late July with 308,218 miles. The ECM had the standard factory program. The truck is a Kenworth W900 “SuperCab”.


The engine test facility:  We (Pittsburgh Power) performed the test for fuel economy using our Taylor chassis dynamometer. Our dyno uses a water brake to control the engine at a fixed rpm and percent load (torque). We also measured the exhaust emissions using a Portable Emissions Measurement System manufactured by Sensors Inc. These emissions measurements were converted to fuel consumption estimates using EPA compliant methods for certifying engine fuel consumption (40 CFR Part 1065). Dyno testing eliminates any influence of external variables on fuel economy such as wind and rolling resistance, driving style, and terrain.


After the baseline testing was complete, the same engine began use of diesel treated with Max Mileage FBC (fuel borne catalyst). The driver noted smoother, quieter engine operation and better pulling power (common feedback from customers). His manually logged baseline MPG was 5.2. The driver noted that fuel mileage gradually increased over the evaluation period. The driver-logged MPG from beginning to end of the 3-month test period was 5.85 MPG. This represents an increase of 13% which included the initial clean-up and conditioning time. The driver-logged MPG for the last 2 months of the test period was 5.94, an increase of 14%. These results are consistent with the dyno results obtained under controlled conditions of rpm and load.


“Return to Baseline” test and repeat: As a check on the driver reported MPG evaluation, we ran a repeat test in which the truck was driven with untreated fuel for ~30,000 miles. This “return to baseline” evaluation began in the fall of 2018 with use of “winter” fuel and lasted for approximately two months. Treatment of the fuel with Max Mileage resumed on Jan. 24, 2019, again using winter fuel, and ended on Mar. 14, 2019. Recorded numbers from the truck owner’s manual fuel log were 2,568 gallons of diesel burned over 14,289 miles driven since he resumed use of treated fuel. That adds up to an estimated fuel economy of 5.5 MPG, significantly higher than the original 4.9 MPG achieved over the previous two-month period. The increase in driver reported fuel economy for this second evaluation was 13%, consistent with previous results obtained with the rolling dynamometer (controlled conditions) and the MPG calculated manually by the owner of the engine from his fuel log.

Dosing instructions

Things you need to know before you begin: You'll need a pair of gloves (Solvent resistant / Nitrile) and measuring device. Be careful not to let the catalyst touch your skin. Please use one of our approved measuring devices or if you want to use your own device, it should be glass or fluorinated plastic.

Dose at every fuel stop. Once you've filled the tanks, measure out the correct amount of catalyst for each tank. The correct dose is one ounce for every 25 gallons of diesel fuel. Use the back of the bottle for reference. For gasoline engines, the correct dose is one ounce for every 30 gallons of fuel, or one ml per gallon. The catalyst is designed to mix itself. That's it!

Frequently Asked Questions

Can I use it for my diesel pickup truck, diesel car, farm tractor?

Can I use it for my gas engine?
