Very knowledgeable…
It was really nice talking to someone who was so knowledgeable about the product and understanding my situation, with my pickup.

What people say
I've been using Better Diesel in my 2016 Ram
I've been using Better Diesel in my 2016 RAM 2500 since my truck had about 5000 miles on it. I'm now at 120000 miles. I know it works, it's not a snake oil. I've had zero fuel system issues and zero DPF issues. I know I'm low mileage truck for it's age. I do allot of city driving and tow my 12000 lb camper with the truck, without issues.

Freightliner experience
I have used this additive in my 2008 M2 Freightliner for years, my regen only comes on rarely and only for a few minutes. This product is awesome

James, I see that you have been a customer since 2017. Thank you for your loyal business and for taking the time to review Better Diesel FBC.
Reduce soot and improve fuel mileage.
I am very pleased with Better Diesel's FBC. I have a 2025 GMC Sierra 3500 HD. I put the Fass EGR filter on it to filter out the soot going into the EGR. It works great. But it reduces EGTs between 200 and 500 F. And I get more soot as it is very efficient at converting the soot into CO2. Better Diesel's FBC has been the solution I've been looking for to help reduce soot and improve fuel milage. My regen frequency was less than 200 miles now I'm upto 400 miles and climbing.
Fast shipping great product
