It works.. nuff said!?
Maybe there is such a thing as a mechanic in a can.I bought a Dodge RAM 2500 5.9 Cummins.It has 218k on it. I live off grid and drive 5.5 miles of slow going, country gravel road to get to my place. I felt the stutter in the engine going around curves and up hills at low speed and RPM. At this time I averaged 15.5 MPG on the factory digital display.I heard about this stuff from an old time that started using it in his old 99 RAM. I took his advice, and started using the full 3 part treatment . I've been consistently using all 3 products for more than a year now. I do the boost dose, 2oz per 10 gallons of diesel. My fuel economy has increased to average 17.4 MPG reading, there is absolutely no stutter at any speed or RPM. I'm NOT a mechanic, but I know a better running truck when I see it and drive it. I've got 248K now and this truck runs far better than it did the day I bought it thanks to a little TLC and the Archoil line.

No opinion after using
I have a 2025 Chevy (Duramax) and run Hotshot transport. I used the product exactly as instructions prescribed.I honestly didn't see any improvement in fuel mileage. In fact, if anything, a slight drop while loaded.However, I did see a noticeable reduction in DEF consumption!I can't say it helps with improving your mileage, but obviously helps it run cleaner! If you have a higher mileage truck and you use the system cleaner product then this? Yea, I can see how it would get you back on track.Will I use it again? Na! Probably not for a long while

Great additive in my opinion.
I will continue to buy this additive. My fuel mileage has increased by at least 10 percent and the engine doesn’t go into regeneration mode as often (2019 Duramax). Made a 100 mile round trip yesterday and got 23.5 mpg at 55 mph with some town driving included.
