Review: 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.
Review: 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.
