    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 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.

          They told me to use premium gas in my 2005 Maxima but I just use reg unleaded. I put 3 to 5 ozs of Lucas in about every 6 weeks and the car still gets great gas mileage and runs clean. Also use Lucas transmission additive and it has help the shifting greatly. I have 130,000 miles on the car and I believe the additives have help keep it performing.

            Have been using Lucas for years now and think it is a great product. It is incredible in Ford products. Will increase gas mileage and make your vehicle run a lot smoother. I have 288K miles on my F-150. It is a great upper cylinder lubricant to increase the longevity. I use it monthly to keep all of the injectors on all of my vehicles clean.

                    I can't say if it cleans, but it does Lubricate. i.e cold starts and ethanol fuels, plus I don't get cheap gas Ping. 4oz per 10 gal. fuel, results in 1+ MPG, so it must be good for your valve guides and upper cylinder. Protect your expensive engine! I buy 1 qt., save the empty bottle to refill with the 4-gal case I purchase (lasts a year)and keep the qt. in my truck's door pocket and the car's trunk.

                    This stuff does the trick. I have a friend who is an ASE certified mechanic swears by this stuff as much as you can for an additive. If your fuel system is really jacked up, you need to clean the throttle body and your fuel injectors. If they're not that bad, but a little gunked up, thrown some Lucas in there.
