Max Mileage, Pittsburgh Power - anyone tried it?

I listen to Road Dog Trucking on Sirius. From 9am to 12pm is Kevin Rutherford's show. They regularly have people call in (Mostly Diesel Trucks) and rave about this product called "Max Mileage". Lately, many have called in reporting great results in gas engines of all types. I am tempted to try it and thought I would see if anyone here has tried it. https://pittsburghpower.com/pages/max-mileage

It's pricey, but comes highly acclaimed. One half gallon is $120. For gas engines, they recommend 1 oz. per 30 gallons. So, one half gallon jug would last for 64 fill ups.

Thanks for any input.

I don’t know of any diesel tundras so probably not many people here have tried this.

Also, while I have no direct knowledge of this particular product, life has taught me that most stuff like this is just snake oil.
