Rated 5 out of 5 by Checkmate This product seems to have solved my problem
The engine light on my Nissan Sentra was coming on occasionally for the last few years. The car was also going into limp mode every time it happened. I had to keep resetting the ECU to deal with it. The code I was getting was for the throttle body. I took it to the dealer and they cleaned the throttle body. The dealer then said I need to get a new throttle body. This is an expensive fix which I didn't do because I don't think it will help. I have read about many people with my car who seem to have this problem. Changing the throttle body doesn't fix the problem from all the reviews I've read.
The car also seemed to be hesitating and running rough at times before the light would come on. After reading the reviews for Lucas UCL, I decided to try it. For the past month since I put it in, the car is running smoother and the light has not come on. I have also been making sure now to only get top tier gas and even premium when I fill up. Hopefully these changes will solve the problem that I've had.

Rated 5 out of 5 by MaddM1ke Helps keep car running fine
I use some of this in all my vehicles everytime I do an oil change. Helps keep all my vehicles running smooth & mpgs decent. Never had any issues using this product. One of my cars has 295k miles and still gets 31mpg. I think some of this lucas treatment helps contribute to that.

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.

Rated 5 out of 5 by Chris96815 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.

Rated 5 out of 5 by HighSierraHiker94 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.

Rated 5 out of 5 by T34pilot 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!

Rated 5 out of 5 by RacerRon 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.

Rated 4 out of 5 by PAKA 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.

I have been using this product for years on all my cars. i can see the longevity in my gas usage and it seems to be a smoothness in my car. Meaning no knocks or pings. In addtion, very easy to use. Measurements, bottle levels are legible and spout makes it easy to apply in gas tank. Once i get my motorcycle will use in that as well. I highly recommend to others!
