    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.

      Lucas = Quality.
      The bigger size makes it MUCH more economical per fill-up.
      I would use this product in three consecutive tank fill-ups, every 6 months.

          Comments about Lucas Oil Products Fuel Treatment 32 oz.:

          The Lucus fuel treatment formula has been a great asset of mine since I began driving. I started driving and owning my own vehicle since about 2007. Since then gas prices have been getting astronomically higher and higher and the best thing I can possibly do for my car and my wallet is to get the maximum amount of miles from every gallon or gas I buy. I remember when I first started using it in my first 1997 Toyota Corolla, I noticed an increase in gas milage after just the first few uses. With that car I went from about 26 miles per gallon to sometimes over 30 miles per gallon. Now I drive an SUV and it is known for SUV to get bad gas milage I can get a little more than 25 MPG while using the treatment. LOVE IT!

          I bought this product due to a recommendation of a good car guy of mine yet after 3 tankfulls considering 50%city 50%highway and light throttle in accelarating in my 99 Corolla which I maintain in great condition, Timing belt done on time, oil changes, etc. I see no improvement. I bought the big bottle so we'll see in the long run but I'm dissappointed so far. I'm gonna hope for the best. I'll recommend it for now but if I go through the whole bottle and no improvement I'll pass on it.

              I was skeptical when I first started using this product but after using it for over a year I am very happy. My car idles a lot smoother when I use it and it also helps my mileage a bit, I drive a gas guzzler so every bit helps. Highly recommended

                135000 miles on engine. Was getting about 13-15mpg. After used and about 500 miles on engine. Was getting 15-17mpg. Probably helps cleanup dirty engine but may do nothing for an engine with lower miles or in better shape.

                    I have a 2009 Honda Accord V6 with variable cylinder management. Every few months, the cylinders misfire after a fuel full-up and the engine starts to run rough till i burn about 1/2 tank of gas and add fresh gas. I was told by the autostore sales man to try this. I drive the car a few miles and the engine performance is restored. Had cylinders misfire 2 times this year and using this problem took care of it. I am going to used this product on ever other fuel fill-up from now on.
