Really has made a difference in the performance of the engine

I have been using your upper cylinder lubricant in my 2014 Camaro since it was new. Really has made a difference in the performance of the engine. Not to mention that it helps keep the intake, injectors and the valves clean. One of the best things you can do for your engine. Lucas products are the best out there and a great value too. - Gordon W., South Burlington, VT

Lucas Fuel Treatment is an awesome product.

I have used this in all my vehicles. So, I knew that it was a quality product. Recently, my son had trouble with his lawn mower. He had let it set over the winter with gasoline in it; unfortunately, the gasoline contained ethanol. When he got ready to use it again this year, it would not start. We emptied the gas out of the tank. We replaced the fuel filter and all the fuel line hoses. The carburetor is complex, so we did not mess with that. We finally got it started, but it ran rough and it only ran at an idle speed, even though it was full throttle. We contacted our local small engine repair shop. We were told that this often happens if you let an engine sit for an extended period of time with ethanol fuel in it. We were told that the carburetor would have to be rebuilt and that would cost about $1,000. Instead, we decided to try the Lucas Fuel treatment. I checked the website, and it said that overtreatment would not harm your engine, so I put the whole 5.25 Oz bottle into 5 gallons of fuel. We put new fuel in the lawn mower and started it. After five minutes, it started running smoothly, but still at a reduced speed and it was smoking badly. After 10 minutes, it was running at normal speed and all of the smoke was gone. It would appear that this fixed the carburetor problem and saved me $1,000. I learned 2 lessons from this. First, never use gasoline that contains ethanol in a lawn mower. And, second, Lucas Fuel Treatment is an awesome product. - Randall B., Comanche, TX

I will recommend your products to my motorcycle riding friend

Recently used your fuel injector cleaner on my 20 year old Motoguzzi motorcycle. I was having problems starting after engine was hot. After pouring a 5 ounce bottle of Lucas injector cleaner in my fuel, the problem disappeared. I will recommend your products to my motorcycle riding friend and continue to use Lucas products in the future, thanks! -Gary G., Baltimore, MD

I have used Fuel Treatment at every fill-up

Have a F-150 purchased with 35,000 today I have 250,000 and have used Fuel Treatment at every fill-up have only needed to change plugs two times no problems with fuel injectors, actually I have had no problems with any part from the fuel pump to the exhaust system. I still pull my 16 ft. fishing boat to reservoirs far and near. I also still drive to my daughter's house 2,000 miles every year. It's my daily driver. -Michael H., Topeka, KS

Great stuff!

Great stuff! Use it in my 1990 dodge W-250 pickup Cummings equipt. I’ve got 850,000 km on her and never had to have the injectors cleaned since I started using this product. First used it ten years ago under advice of a friend, never will not use it again, more affordable than “other” products on the market and you know for sure, if it’s got the Lucas name on it, it’s a good product. Thanks for the engineering on this product Lucas! -John M., Delta, Mississippi

After Pouring The Treatment Into My Gas Tank I Started To Feel The Difference

This product works. After using the fuel treatment for my 2008 Ford, I can feel the effects. My car has 100,000 miles on it and after pouring the treatment into my gas tank, I started to feel the difference. I would highly recommend this product. -Aidan B., Elma, NY

I Keep Lucas In Everything I Own.

Just wanted to let whom ever know that I don't usually write reviews. This one out of about ten that I have done in my lifetime. I have been using Lucas fuel treatment for along time (over 20 years). I have a lawn mower that is 22 years old never had the carburetor off of it, still using it to this day. I had a 13 year old $60 Walmart weedeater that still had the original carburetor on it that was never removed(finally wore the motor out and had to get a new one). I have an 2004 Monte Carlo with 230,00 miles that still get 29 mpg. I keep Lucas in everything I own. It works. When I fill up gasoline cans I put it in before I fill them up. -Chris S., Cumberland City, TN

This product WORKS! I highly recommend it.

A month or so ago, I purchased two bottles of Lucas Upper Cylinder Lubricant and Injector Cleaner to try in my 1999 GMC Sierra pickup, which I bought new in January, 1999. For two years I had been trying to solve a problem with the truck. It would be very finicky about starting. If it did not start on the first try, it would flood and then be really difficult to start. More of a problem was that for the first ½ mile or so, the engine was subject to quitting and restarting, in its mildest form, you could say that the vehicle was hesitating or missing. But basically, it was just episodes of "bucking." It was very annoying and significantly made the truck unreliable. That first year, I had the truck in the repair shop off and on for about 3 months. Ultimately, the repair shop replaced the fuel pump in the gas tank. It was about a $550 charge. It did not fix the truck. I continued to drive it, but the issue became worse. Then, one Saturday morning in January this year, following a " rough" drive to the coffee shop, I decided to stop at AutoZone and get some fuel treatment. They recommended your Lucas Injector Cleaner. I filled the vehicle with gas and poured a bottle of the treatment into the tank. It improved substantially, but not completely. But I was encouraged, so after that tank of gas, I filled it again and put another bottle in. The symptoms went away completely and have not returned. So for about $12, this long time problem was solved. Just amazing. Later in January, my 2013 GMC Sierra pickup had the service engine light come on. I had AutoZone check the engine code and it was one that could have several causes, but all had to do with the fuel system creating a problem. I thought, well your fuel treatment worked for the other truck, so I decided to try it on this pickup. Again, two bottles and two tanks of gas and the service engine light went away. Just-amazing. No telling how much money your $12 Injector Cleaner saved me. I am a believer. It is just great stuff. And, it is a minimal cost for potentially solving expensive problems. I highly recommend it. And thanks for putting such a terrific product out for such an cost effective price. GREAT JOB! -Ray Thomas, Burleson, TX

No check engine lights at all and the motor seems to run smoother.

My 2004 Sienna would throw a P0430 code regularly. Sometimes within minutes of resetting the light. I tried the Fuel Treatment and went on a 600 mile trip. I used the Fuel Treatment again at the second fill up. No check engine lights at all! The motor seems to run smoother too. I think I will try to not use it and see if the light comes on. If it does then the fuel treatment really works. Well worth the money for sure. -Ben, Chapel Hill, NC

Thank you Lucas for a great product that performs as advertised!

Just finished a 3250 mile trip in our 99 Dutch Star using Lucas Fuel Treatment for the first time. Added at fill up according to your directions and am thrilled with the results. We are towing a 4500 pound Edge and the coach is at maximum load. Our fuel economy went from the low 8+mpg to 9.9mpg average for the trip! We are powered by a CAT 3216 rated at 300HP. Needless to say it will be added at all fill-ups from now on. Thank you Lucas for a great product that performs as advertised! -Mark N., Edmond, OK
