Gearing Canadian Kenworth & Differences in Detroit and Cummins Aftertreatment Systems

What were they thinking, maybe the problem is they do not think? A client of ours is purchasing a new W900-L or W990 in the Toronto Canada area, the truck will be powered with an X-15 Cummins and the 18-speed transmission, which has a final drive of .73 thus making it a double overdrive transmission. The dealer has a 500 horsepower, 1750 torque at 950 RPM, however the rear gears are 3:70 with low pro 22.5 tires. Really? Are you kidding me? This spec dates back 30 years ago. With a peak torque at 950 RPM the best operating range...

Differential Gear Ratios

Differential gear ratios; there is a lot of confusion in the trucking industry about what is the best gear ratio for pulling power, fuel mileage, and a good cruising speed. This article will pertain to the over the road semi truck, NOT heavy haul, or vocational local trucking. To pick the right rear gears you must know the peak torque RPM of your engine, the ideal cruising RPM, and the speed you mostly drive on the interstates. Today almost all transmissions are double overdrive which is a .73 final drive gear. The standard 13 and 18 speed transmissions are all...

GREAT PRODUCT

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 !!!!!

Magical juice

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.

Thanks to Let's Truck / Power Hour for the recomendation.

It’s best product since I have been using this my truck regen less engine runs smoother and mileage is increased

Put that Sh** in everything

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 8 oz 8 fill ups no results

Used 8oz (160 gallons) for 8 fill ups did not see a decrease in def usage or better mpg
2023 dd15 auto casscadia

great product!

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.

Never got it

I never get my cup or my measuring syringe

Excellent

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

Power diesel fuel
