    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.:

          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!

            Comments about Lucas Oil Products Fuel Treatment 5.25 oz.:

            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.

                      We starting using Lucas Oil Gas Treatment after we had our exhaust system completely replaced where the repair shop blew it out doing their "fuel system" cleaner. We've been using it for over 8 years now - every time the Ford Dually gets filled up (dual tanks).

                      I totally recommend using this product. Please don't let the repair shop ruin your exhaust system!

                            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?

                          I have another question.
                          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,

                            Hi Roy, good question! This fuel treatment does not repower the old gas that has set for about two years. I would suggest you to add this fuel treatment when you add new
                            gas to your vehicle.

                        • 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?

                            So far we have not received any of such complaints after using this Lucas Oil Products Upper Cylinder Lubricant with Injector Cleaners in any of the vehicles from our customers. Hence, I would suggest taking your vehicle to a certified mechanic for a proper diagnosis to avoid intermittents.
