I have used this product on all my cars for years. Best additive to add thousands of miles to an engine and increase fuel mileage. I keep a bottle in the trunk at all times in a large 1 gallon zip lock bag to catch any leakage that can cause a big mess.
I often do huge cross country trips and it's partly due to this product that my cars hold up to the large distances I travel in a day. Thank You Lucas

This product may or may not work. It was certainly easy to use (Just pour it in gas tank). I have used the Lucas Oil Treatment and think it works well, so I trust the Lucas name. It's hard to say if my miles per gallon increased when using this product because the weather changed - it got warmer - but I may have had a slight increase in miles per gallon.
My Ford van has 173,000 miles and ran well before adding the Lucas Upper Cylinder Lubricant with Injector Cleaners and ran just as well after adding the product.
Any benefit that happened could have been attributed to Lucas Upper Cylinder Lubricant with Injector Cleaners, but may not have.

    Comments about Lucas Oil Products Fuel Treatment 32 oz.:

    I really like using this product on my 2003 Ford Crown Victoria which I have over 150k miles on. I used to put it on every time I would put gas but it's too expensive for me to do. Now I do every long trip I take or when the idle gets a bit rough. It really does work on that idle. I recommend to everyone.

      This product along with all Lucas products is just amazing! Tried it 10 years ago when my truck would not run right and tried everything else before this product with no reults. I put above the recommended amount the first time and after 1/2 tank of gas, my truck ran better than it ever did. Use this every oil change or sooner in every vehicle!

        Was recommended by an exotics sales and service center for doing the job while not damaging sensors, fouling spark plugs, etc.

        I used it on my exotic and there were no unusual exhaust smells, no idle issues, no hesitation, an so on.

        Seems to be good - will use again.

          Good product! I have an 04 Tahoe with 185k. I have noticed +1-3 mpgs depending on the type of driving. With almost all fuels containing 10% ethanol, I figure it wouldn't hurt to keep the engine seals lubed by using this product.

              I thought my f250 v10 was running great, but I was getting awful gas mileage. (7mpg) I decided to that it couldn't hurt to try some Lucas fuel cleaner. I dumped 3 or 4 oz in at half a tank. Within 5 minutes of driving I noticed it has better throttle response and a little more power across the board. Best part of all is that I am past the amount of miles where I would have run out of gas and still have a quarter of a tank left. I do not have solid numbers at this time, but its worth it for the regaining of performance.

                      A:

                      Hi Bobbie, glad to help you! Lucas Fuel Treatment is formulated for both gasoline and diesel engines, carbureted or fuel injected. It cleans and lubricates the carburetor and injectors and causes the fuel to burn more thoroughly for increased power and less fuel consumption. Lucas Fuel Treatment should definitely be used in vehicles that require leaded fuel because it actually replaces the benefits of lead in gasoline without causing harmful emissions. Use it to pass smog tests. Finally, it totally neutralizes the harmful effects of low sulfur diesel fuel. Lucas Fuel Treatment complies with the federal low sulfur content requirements for use in diesel motor vehicles and non-road, locomotive and marine diesel equipment engines.
