Archoil AR6500 Diesel Treatment (40 oz) - Treats 400 Gallons - Additive for All Diesel Vehicles

The price and quality of product made me try it. It's been a good change. However, the large jug was shipped in just a plastic bag. The nosel was bent and the cap broken so could never seal it back up without it leaking. Recommend shopping in a box.

Been using it for almost a year now. I definitely get better gas mileage and when i don’t run my truck with it, i can definitely tell the difference. Highly recommend

This is the first product I have used that actually does what it says. For a 2015 F250 powerstroke, gained an average of .8 MPG, but more importantly, stretched out my regens about 70-90 miles further.

Didn't help with my mpg but really helped with the dpf filter cleaning. Light was coming on every 40-50 miles. After using this for 10 tanks of deisel the light only comes on about every 3k miles. I now use it regularly. It seems to really help and would reccomend.

According to just about everything that I've read, watched, or heard, if you're not running an additive in your diesel engine with today's low sulfur fuels you're essentially asking for trouble. Archoil consistently ranks at or near the top in testing and "bang for your buck", which is good enough for me. I can't really say that I've seen any changes in fuel economy, but that's not what I'm using it for anyway. I look at it as cheap insurance against the dreaded CP4 pump failure. So far, so good!
