Pittsburgh Power Max Fuel

Saw this on FB marketplace a few days ago LOL.

 

Exactly what Cummins is doing on 2 nd gen x15

 

My uncle swears by it, tried 2 gallons on my truck and didn’t really notice a difference, I do use power service every/every other tank though which you can get any where

 

I tried it in an 06 isx. Didn’t see any noticeable changes.

 

I started using it after a friend said he did in his last truck
He had 7-800k on it when started and said for a few weeks it coughed and puked, he had to get a programmer to do regents and reset codes but said after a few weeks it cleared up
He then sold at 1.2 million
He said they pulled the def filter and they couldn’t believe how clean it was

I only had around 100k on this one when I started so can’t tell what it’s doing but it’s relatively cheap so I’ll continue using it until I do a filter burn and see what they say

I also have another friend who has a diesel tractor that is a year or so old with low hours that was running rough
He tried it and said it cleared it up

 

Here's the problem I have with products like this: what they claim they're product is doing would actually have the opposite effect they are claiming.

For example, if you claim you are reducing combustion temperature you are also reducing combustion pressure. And that reduces power. Yes, it also reduces NOx. And frankly, introducing a catalyst to improve combustion would actually tend to increase combustion temperature even though it might lower EGTs allowing the engine to use more of the heat to generate power, leaving the exhaust steam cooler. Basically the combustion process completed earlier in the power stroke and able to be effectively harnessed, whereas inefficient combustion leaves more of the heat generated late in the stroke and even after the exhaust opens, doing little for power and spiking EGTs.

It would also be interesting to know what those metal catalysts are doing to fuel lubricity.

And as always, there is the most relevant question. If the manufacturers could improve their products so easily, they would already be doing so.

 

My experience with PP Max Fuel.
i bought my first emission truck in August 2021. the quantity control valve was bad, the idle speed was jumping all over the place. I picked up the truck and put max fuel in, bobtail 85 miles to wait for a trailer. When I went to pick up the trailer the idle was smooth. It still is. I don't know if it saves me def or anything else. I use it in every fill. I have a device that let's me force a regen. I do it every month. My truck only had 1 dash board forced regen. After I idle 3 days straight in ca. in August.

 

I started using Max Mileage about three weeks ago. Fuel mileage went from 6.2 to 7 mpg in the first 2 days. I went from using a half gallon of DEF in a 1000 miles to barely a .25 gallon every 1000. I also noticed a huge difference in how the truck idles. If you notice that you’re using a lot of DEF try this product one time and see if it helps. If not your out $200 bucks and try something else. That’s how I looked at it.

 

Your def seems way off
I agree that the product seems to be making a difference but not so sure it increases MPG but def is normally somewhere between 5-10% of fuel usage
That would mean you fill up on def like once or twice a year

 

For the last three weeks that I have used this product the numbers aren’t lying. Maybe I should have said a quarter of a tank of DEF instead of .25 just to be clear. My fuel mileage jumped as well. I’m not endorsing this product I’m just stating what I’ve seen personally.
