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 This jawn is good stuff Stuff is good I recommend it 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

Rated 5 out of 5 by Excellent great product to keep my motor running for the long -term. October 8, 2015
Rated 5 out of 5 by Wonderful Product First thing, Lucas Oil Co, is a great American company out of Indiana. Sponsoring every type of racing you can thing of. Of all there products, the most used by me is the Fuel Treatment-Upper Cyl Lube. I add 2 oz.'s of it to each of my four vehicles after a fill up. Our two daughters live over in the Southbay, when they visit I add it to their cars also. I may also use injector cleaners. octane boosters and fuel system treatments at times, but is great that Lucas provides a product for upper cylinder lubrication, this treatment elimates nightmares concerning engine problems. It probably also lubes the in tank fuel pumps. August 25, 2015
Rated 5 out of 5 by best value If you want to take care of your fuel use this ! best to buy the large bottle and it works. August 1, 2015
Rated 5 out of 5 by keeps my 19 year old truck going I have used this fuel treatment for about ten years and my turck keep on going. My 2002 sunfire has 245,000 and never replaced the engine but have used this off and on after I gave my daughter this car about 4 years ago. When she visits I put some in the tank. July 26, 2015
Rated 5 out of 5 by Lucas Fuel Injectors Lubricant It does its job. I put it in all my vehicles, it helps clean the fuel injectors & cylinders run smoothly. July 19, 2015
Rated 4 out of 5 by good price and quality Well I have a car that is 25 years old and if I don't use the Lucas product It won't perform that well. It clean the inject very good and I will still use it every time. June 24, 2015
Rated 5 out of 5 by I put this in every time I fill up! The guy at pep boys made this stuff seem like gold as he was telling me how much better power and MPG I will get by using it every other tank. I reluctantly agreed to get a single serving bottle as well as the larger bottle to fill it back up. I tried it out and now I am a believer! I can DEFINITELY tell when I don't have that in my tank and will put that in all of my cars every time I fill up. Definitely worth the money, and I highly recommend it! August 4, 2015
Rated 4 out of 5 by easy to use not sure how well it works but I do use in my 46 ford Woodie, 56 F-100, 2006 Lincoln pick-up, 3 Harley Davidsons, Ride on Mowers, a jet-ski and a Boat with an outboard and so far I haven't had any problems. some of these vehicle are parked up for long periods (sometimes 12 plus months) and I feel the leaving the upper cylinders lubed helps for when the motors are fired up again.
