Rated 4 out of 5 by Lucas aaditive I use this primarily for upper cylinder lubrication. Yet it is essential that attention be paid to current automotive fuel systems. I presently drive a 2015 Hyundai Sonata and discovered that there is a fuel additive provided by them for areas where top tier fuels are unavailable. That is anywhere. August 15, 2016
Rated 5 out of 5 by I use it regularly. This is the only fuel additive that I use. It keeps my car running smooth and it stabilizes the fuel. It improves idle, acceleration and keeps the fuel system nice and clean. I use a few ounces every fill up and it keeps my car running smooth. I also never ran into problems using Lucas products. I highly recommend using it on the regular. August 10, 2016

Rated 5 out of 5 by Very impressed!! I have a 1993 Toyota 4Runner (5sp 4wd) with over 277,000 miles under its belt. Right after my last tune-up/oil change at Pep Boys, I put Lucas in my gas tank during a fill up. I have been following this procedure twice a month for the past 4 months and have noticed a fair increase in my mileage, considering that most of my driving is in commute traffic. I've increased from 13+mpg. to 16+mpg. August 4, 2016
