Lucas Upper Cylinder Lubricant & Fuel Injector Cleaner (5.25 oz.)-12 Pack

A fabulous deal on the best fuel additive in the business.

Git rid of some of my engine code. car seamed to have a little more power after/during usage. Going to use it more often. Got slightly more hway avg mpg for the same trip I make allot.

Add one to every other gas fill up in your vehicle. It cleans the fuel injectors. This really works, I know by experience! Great additive!!

I personally have tested this project and I’m on my fourth tank and it seemed to get better every time I put this in. I was in the automotive field for 30 years never believe in snakes but this one works simple use

Best price around and a very trusted name, Lucas!

With Lucas you can’t go wrong. Works well in marine and auto applications.

I have a little 4 cylinder automatic. With just one bottle and a full tank of gas, I have better take offs from lights, climbs faster with a smoother gear shift, and almost no valve knock! Cheaper than any other retailer and fast delivery. I have over 143,000 miles on this 2018 Sportage and she's driving GREAT/

I’ve used this product for years. Typically use it on a full tank of fuel after every oil change. I recall seeing mpg’s decline in a diesel truck that I had, but don’t notice a difference in gasoline engines. I use it because I believe it is keeping my engines healthy and clean. I have recently began adding to my 5gal gasoline cans (obviously not the whole bottle) for mowers, generators, and utv’s.
