  • Great stuff!
Top notch all season, all protection diesel additive! With ULSD now a days and high pressure fuel systems on newer diesel vehicles I run a dose of treatment every tank and can tell the power difference with this additive and increased fuel mileage! Great product! All I will run from here on out!

  • No complaints
Tractor starts well, even in cold weather.

  • Diesel additive
I've been using this brand of diesel fuel additive in my John Deere tractor for about 18 years and have never had a fuel issue. Works very well, and quite economical.

  • RECOMMEND! 2014 Duramax runs BETTER THAN EVER! Even getting 22-23 mpg on HWY!
I drive a 2014 duramax that is fully deleted including the DEF. And this product has made it seem like the motor runs a lot better, less resistance on injectors and ensures the best MPG possible!

Great product.

  • Highly recommended
I see very slight milage improvement. I use to protect my diesel fluid pump in my F-350. My engine seems to be a little quieter and starts easier in 30 degree weather. There are cheaper places to get it and you can buy in a 1/2 gallon.

  • Best preformer in Diesel Treatments
Did a lot of research prior to picking a diesel treatment product and these guys were the clear leader in all tests I found out there. Hard to find unfortunately in stores because of the more popular brands that actually preform far worse that this.

  • Used on a new utv so I can’t compare to not using it
I plan on using this product at every fill up. I have to figure out how to get the ratio right. It would be nice if they sold a bottle for 5 gallon mic
