The product was simple to use and works great. I get great Gas Mileage and you can feel the difference as soon as I start driving. I also bought the 3oz bottle so that I can refill it and put it in the gas without trying to measure how much I need every time. This is a must to have and without it you are crazy. Trust me my Honda Pilot with 111,028 miles on it drives like new. So don't believe it till you have tried it.

      Comments about Lucas Oil Products Fuel Treatment 5.25 oz.:

      I moved my 04 Taurus out of the garage and moved another car in it's spot until I could finish the other job I was working on. Fours hours later, I went to move the Taurus and to my surprise I had left it running. It was not heating or anything, so I felt safe. The next morning it was ticking and got louder ever since. I checked the oil and it was a half qt low and I added oil. I also added the Lucas fuel treatment at the next fuel up. I started the ca this morning after 108 miles and no more ticking. This stuff really works!

              Comments about Lucas Oil Products Fuel Treatment 5.25 oz.:

              This product really works. It takes a little time though. You will see mileage per gallon decrease slightly as the cleaning product is running through the car's system. Once its flushed out (about 1 or 2 gas fill ups) you will see a big difference. I have a 2004 Toyota Prius with 65,00 miles on it (at the time) and I was only getting 41 to 42 miles to the gallon, which is great for a normal car, but not from a Prius. I decided to use this product and within a short amount of time my miles per gallon shot up to 50! It was really exciting to see how my miles per gallon steadily increased. My car runs smoother, it feels lighter, works better, and I know it will last longer. So don't hesitate any longer! It's safe for your car, and it works!

                I'm a long time car/motorcycle person, a maintenance freak and not a fan of "bottle-fix" products. This was recommended to me by a skeptic and mechanic who had great results. Used in my Acura TSX, smoothed out the idle and gained a solid 1.5mpg. I had a flat spot in my Speed Triple, even after going through all 3 carbs and the ignition. a splash of this in a fresh tank of gas fixed it in 25 miles. So last week I poured a bottle in our motorhome when i pulled it out of winter storage, which has had a mildly pulsating idle despite a full tune up, 1200 miles of premium fuel, 3 bottles of my old go-to, Chevron fuel injector cleaner and a whole bottle of Sta-Bil last winter and this winter. It was also rather anemic for a 67k mile EFI 460 in an E350 chassis. not only did it all but cure the idle issue in short order, it runs like it's got a brand new engine. Lucas now has my attention!

                  while not having great faith in "bottle fixes" I tried this after a trusted skeptic had really great results. Used in in my Acura and smoothed out the idle while adding 1.5 MPG. Used it in my Speed Triple and also smoothed out a flat spot I could not remedy going though the ignition and all 3 carbs. Lastly I poured it in our motor home that has an EFI 460 last week with a slightly pulsating idle that also couldn't be cured with ignition tuning. it not only fixed that but really woke up the beast from within. I have 2 more bottles on the shelf as I type. really great stuff!

                      Started using this product in my 89 ranger with a 3.0 vulcan, after about 3 days of driving with Lucas treated gasoline, I felt like my engine was happier and made a little more power. After putting some royal purple and a good oil filter, and started using this, the ticking my engine was making I no longer heard! Very happy with this stuff, easy to use, just give it a couple squeezes into my gas tank then fill her up lol. The ONLY thing I don't like is the fact that it calls for 3 oz. every ten gallons, but the big 32 oz. bottle only has 2 oz increment marks. Not really a big deal but over all definately worth the money.

                            Hi Aj, glad to help you! Lucas Fuel Treatment is formulated for both gasoline and diesel engines, carbureted or fuel injected. It gives your fuel system what it really needs - a blend of super slick oils and additives with a high detergent action that allows the engine to operate at maximum efficiency. Also, 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. Key Benefits: A great tune-up in a bottle, Cleans and lubricates the fuel system, Neutralizes low sulfur fuel problems, Increases power and miles per gallon by burning excess exhaust emissions and Increases the life of pumps and injectors.

                            I'm glad to be of assistance! No, Lucas recommends running it with every fuel fill up because it is 100% petroleum based so it can be used every fill up. The way the fuels are today, they lack the lubrication that is much needed in your fuel jump and the injectors. It will run much smoother at idle and better performance as this product will burn your fuel more efficiently.

                        • Q:

                          I recently purchased a bottle of this fuel treatment at Advanced Auto Parts and found it strange that the bottle wasn't sealed. There was no foil on the top of the bottle either (like you see on bottles of oil). To me, this didn't see normal. I went ahead and poured it in my gas tank anyway, as it didn't appear that it was tampered with.

                          I'm just curious, is this normal for it not to be sealed?

                          Will the lucas fuel treatment help the gas that has been a car or truck for about two years?
                          I have rebuilt the carbs & before I start the engines what shoud be done with the old gas?
                          I need something that will help the gas until I can get new gas & then put in the treatment.
                          Is there something that I could use instead the lucas or seafoam?
                          Thanks,

                        • Q:

                          The bigger bottle of this same product says that over dosing won't harm the engine. I have a stuck float in the carburetor on my motorcycle, so my question is: Is this a fuel product that won't harm my engine if I add the entire 5.25 oz bottle to my gas tank that has 4.2 gallons of gas in it?

                            The Lucas Oil Products Fuel Treatment 5.25 oz. - part# 10020 may help but I would always recommend fixing the problem by finding out exactly the cause of ping and knocking on your Toyota Camry and then replacing the necessary parts.
