Lucas Fuel Treatment is an awesome product.

Randall B., Comanche, TX

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.

Really has made a difference in the performance of the engine

Gordon W., South Burlington, VT

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.

After 30 Miles The Rough Idling Subsided

Henry G., Lawrenceville, GA

At 65 years old not much surprises me. I have NEVER used additive in an auto. I have a 2012 Hyundia Genesis with 209,000 miles. It was idling rough. I'm thinking I need a $300.00 cleaning at the dealership. I decided for once in my life I would try an additive. I went to Walmart and of course they had 50 different kinds. I pick LUCAS because they are very reputable company. OK let get to the meat of this story. I put 6 oz of LUCAS UPPER CYLINDER lubricant in my tank. My hand on a bible after 30 miles the rough idling subsided. I would not believe this if it had not happened to me. Jaw dropping moment.

Within a half hour my gauge started working again.

Stephen H., Redlands, CA

I started using the Lucus fuel conditioner [Lucas Fuel Treatment] when my fuel gauge in my Ford diesel truck got stuck. I was told by a friend to use it for this purpose, and within a half hour on the road after using it my gauge started working again. If you use it for nothing else, just solving this problem alone is worth it.

I’ve used Lucas injector cleaner on my 2007 chevy Impala with good results.

Robert N., Balaton, MN

I've used Lucas injector cleaner on my 2007 chevy Impala LT 3.9L v6. Good results. Even today I was going up a step grade and before it would always down shift going up. Well today it didn't shift down to a lower gear at all. And you could hear it with that low tone of steadily going up the hill. Always use this injector cleaner from Lucas by the quart or gallon. Then just add a portion to a 3 oz bottle to add to a fill of gas.

I can definitely feel the difference…

Gus G., Chandler, AZ

I use the Upper Cylinder Lubricant with Injector Cleaners product every time I put gas in my 2013 Harley Davidson Ultra Classic. I can definitely feel the difference after 1/2 bottle of this in there. Bike usually feels sluggish in warmer temps; always ran real good in cooler temps; but with this stuff, runs just as good in warmer temps. Pulls hard too. Not sure what's in this stuff; but it works!

My 2008 Dodge Ram 3500, 6.7 Turbo Diesel was plagued with code 0340...sticking turbo vanes. All remedies pointed to turbo removal. After a gallon of Lucas Fuel Treatment the code has cleared and all turbo and exhaust brake function has returned to normal saving me at least $1500 to $2,000. Thank you Lucus! If only more Dodge owners knew.

Fuel Treatment Stops Stalling in Honda

Frank A.

My 2001 Honda was stalling every two minutes. I went to my mechanic, he said he was way behind on some cars that he wouldn't be able to see my car until tomorrow. He gave me a small bottle of your fuel injector cleaner. Told me to pour it in the gas tank an drive it for 10 - 15 minutes... It was running smoother then silk after about 10 minutes.. I had never seen a additive of any sort actually work. I put a bottle in each of our cars once a year now. Thanks!
