Great stuff!

John M., Delta, MS

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!

Michael H., Topeka, KS

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.

I will recommend your products to my motorcycle riding friend

Gary G., Baltimore, MD

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!

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.

As far as I’m concerned you cannot find anything better for the money.

Stephen

As a retired owner/operator of 36 years, all I ever used is Lucas Fuel Injector cleaner. I used it in all my trucks and in my reefer units. A few of my friends and I used to buy 15 to 25 CASES at a time. I still use it in my pickup, my wife's car, my boat, lawnmowers, weedeaters, chainsaw, power washer. Anything that I own with a gas or diesel engine gets Lucas Fuel Injector Cleaner. I have recommended to my friends and anyone who asks me what I use. As far as I'm concerned you cannot find anything better for the money.

YOU SAVED ME $2,000 at the dealer!

Howard

I have a 2012 VW TDI, been at the dealer 3 times for issues with hesitation. After spending $1k on cleaning tank, filter etc, they wanted me to spend $2k more on new injectors! I love Lucas for my sons dirt bike, so I ordered the fuel treatment! After 1 day with this in the tank, ALL THE ISSUES WENT AWAY! YAHOOOO, saved me 2 grand! Thanks Lucas, this is a great product! I'm bringing the VW dealer a bottle! You guys make a great product!

Great Product!!!!

Jermy R., Stockbridge, GA

Great Product!!!! AS a true believer in the Lucas Oil additive during oil changes, I decided to use the fuel additive in my 2015 Dodge Challenger RT (5.7 fuel saving engine) as it got some bad gas during the Gas shortage here in GA recently. I bought the small bottle from AutoZone for my 19 Gallon tank of the Muscle car and Oh boy!!!!!!! The product increased performance and restored my lost horsepower. Thought I was Blade, Ghost Rider or Vin Diesel, as the product made it Faster and more Furious!!!!!! Thanks Lucas!!!! I think I will use it around twice a month on Fill-Ups. What the Heck every other fill-up.

THANK YOU , Lucas, for such a superior line of products.

James P. Jr., Laplace, LA

I have a 2005 Dodge Dakota with 130,000 miles. Recently I started to use full synthetic oil. I noticed I had a minor tap in the engine. On my recent oil change the attendant heard this tap and recommended using your Heavy Duty Oil Treatment . Almost right away the tap was gone and so far it hasn't come back. I already use your gas treatment. THANK YOU Lucas, for such a superior line of products. I will forever use your oil and gas treatment!
