## Description

1

Review: 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.
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.
