Fuel Treatment

A powerful blend of oils and additives that contain no SOLVENTS. Designed to increase power and fuel mileage and also lower exhaust emissions through a more complete combustion.

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.

Lucas Fuel Treatment complies with the federal low sulfur content requirements for use in diesel motor vehicles and non-road, locomotive and marine diesel equipment engines.

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

You have earned my business for life

Bought a 2014 Chevy Express 2500...nice van with a rough idle. Changed fluids and plugs, made no noticeable difference. Changed oil again, this time with 1 quart of Lucas Oil Stabilizer and also added Lucas Fuel Treatment to the gas tank. After 1 month, the idle is so smooth, sometimes I actually can't tell that the engine is even on. You have earned my business for life.

YOU SAVED ME $2,000 at the dealer!

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!

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

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.

After 30 Miles The Rough Idling Subsided

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.

It’s the best product on the market!!

I use Lucas Upper Cylinder lubricant at every fill up in my 1997 Ford Ranger. It's the best product on the market!! I get improved fuel mileage and easier startups and no hesitation, especially when accelerating onto on ramps and when passing. I also like Lucas Slick Mist in between waxings.
