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
  • Increases the life of pumps and injectors

HEAR IT FROM OUR CUSTOMERS

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

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!

Just wanted to offer high praise for your fuel treatment…

To the Lucas Oil team, Just wanted to offer high praise for your fuel treatment that I had used, on the recommendation of a buddy of mine. The difference in gas mileage is paramount, and the results speak for themselves. While I don't have the longest commute to work, every little bit helps, and your fuel treatment is a big help. In a day and age where it seems like most companies design products with the goal of cutting corners in mind, it's clear that that's not Lucas Oil's mission and philosophy. You pride yourselves on quality work going into quality products, and it shows. The chance to support American-made products is a bonus, too -- that's a long-instilled preference of mine. I'd recommend your products as well, and you guys are on the fast-track to earning a customer for life. Thanks, and keep up the great work.

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.

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.

I want to say your products are amazing.

I want to say your products are amazing. I have a 95 Toyota 4Runner with the 3.0 V6 and the car is very sluggish on Hills especially when towing my boat. I went fishing and put a bottle of Upper Cylinder Lubricant in the gas tank on the way up and one on the way down. Well, now that I’m back the car now has more power and better fuel economy. I was very impressed and now use it on a daily basis. The car has over 203,000 miles on it and it runs better than its ever been. My next experiment is your oil stabilizer in my dads truck. That’s a 89 Toyota pickup with over 281,000 miles on it and it will hopefully take away some of the knock and help the 20w-50 weight oil flow better in the cold mornings. So thank you Lucas Oil and I plan on buying more of your products!
