Good stuff, convenient to use the Subscribe & Save option to never run out
Good stuff, have tried several diesel additives. This seems to be the best all around. (And the bottle doesn’t leak!). There is a winter formula for anti-gel as well as friction modifiers and such.

Seems to do the job well.
I inherited a GMC truck with an LB7 diesel motor, which is notorious for injector failures. The previous owner had used a far more expensive and hard-to-find diesel treatment with no injector problems thorugh 170K miles. This product appears and smells exactly the same, so I am guessing it's using the same cleaners in its formula. I've used it for 30K miles and am hoping it continues to prevent a $5K injector repair.

Good product
Fuel mileage has increased since I started using this at every fill up, close to 2-3 mpg.

it works as good as any other similar product
06 lbz runs smoother it seems to help, mileage didn’t change much but it could be because I got a heavier foot!

This stuff simply works!!!
I have a 2016 RAM 2500 with a Cummins diesel. This stuff flat out works - 1-2 mpg better than without it. Truck runs great, and I don't know what more I would need to say. At today's fuel prices, it's like getting 10% off on your fuel. Highly recommended!

Great product
Definitely worth the money

This is a must for anyone with a cp4 fuel pump. Do what you can to provide extra lubricity for North America diesel before your cp4 grenades. Plus regen frequency has certainly dropped and the extra cetane definitely gives my 2023 duramax more pep and reduces the notorious pedal/turbo lag when slamming pedal to floor. Not sure on fuel economy, I tow and drive A LOT for work and I'm not paying attention to an extra 1 mpg when I'm filling up 3-4 days a week as it is. I'm buying this to save myself a broken heart from a cp4 grenade. 5/5. Bit expensive but nothing compared to a new $15k fuel system.

i didn't notice a difference.

I use this additive as well as the AR6300 in my truck and I will not change it unless I have to, my fuel efficiency improved and my regent are actually down. I was skeptical but their claims are relatively accurate.
