Lucas Fuel Treatment is formulated for both gasoline and diesel engines, carburate 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 carburettor 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 sulphur diesel fuel. Lucas Fuel Treatment complies with the federal low sulphur content requirements for use in diesel motor vehicles and non-road, locomotive and marine diesel equipment engines. Directions for use: The recommended dosage is 2-3 ounces of Fuel Treatment for every 10 gallons of gasoline or diesel fuel. Pour Lucas Fuel Treatment directly into fuel tank. Exceeding the recommended dosage is not harmful to your vehicle.

Started using this in March and was getting ~280 miles from a tank of gas. After a dosen tanks I was getting ~400 miles/tank. Kept using until the whole galon jug was gone but didn't get any further improvement.Great product to run a few tanks with, will clean injectors (and maybe sticky valves), restore your lost mpg rating.

I’ve used this product for years to keep my vehicle in top form. It keeps the engine clean and improves the quality of the already Premium gas I fill the tank with. You only need 3 oz. per 10 gallons of fuel so a little goes a long way. A great value for the price.

I've been using this for years in my 2011 Toyota Avalon (178k miles) and my 2020 Nissan Frontier. My mechanic pulled the Toyota Direct Ignition Module and plug on the Avalon and could hardly believe how clean the cylinder and valves were. He credited this Lucas additive. The Avalon burns zero oil. Like others, I buy the gallon size and refill the quart bottles I in the Avalon and the Frontier. I add about 5 or 6 ounces to every fill-up. Yes, it saves gas, but more importantly, it saves your engine.

Great product. I use the Lucas fuel treatment in a diesel powered truck and a gasoline powered boat. Was having a lot of problems with the boat engine. The MAP sensor kept getting dirty causing the engine to die. After treating the gas with Lucas the problem disappeared. Since then I add the Lucas fuel treatment every fill up and haven’t had a problem.
What I like about this Lucas product is that I can tell that it’s working in about one to two miles after filling up my tank. The pedal quickly becomes softer with less effort to press on the gas pedal. What I like most is that in addition to cleaning the TBI this fuel stabilizer helps improve gas mileage. I have tried other fuel injection cleaners and while they may clean, Lucas is the only product that I have found to actually improve my mpg in the city and especially on the highway.
I make several 3000 mile trips around the country each year. My pickup is a 2006 GMC Sierra, 4 wheel drive, It has over 254k miles on it. Keeps getting better gas mileage all the time. Use it religoulsy in North country cold weather!
About 15 years ago I started using Lucas Upper Cylinder Lubricant in all my equipment and vehicles. When I initially tried it, I was not sure it did anything special, but decided to try it in a 2007 Honda Civic I used to travel to work, a 90-mile round trip. The first few tanks, I was not sold on it, since I could not tell for sure if the improvement in gas mileage per tank fill up was actually from the Lucas Upper Cylinder Lubricant. I did a random test of 3 tanks with Lucas Upper Cylinder Lubricant in and 3 tanks without. During the 5-week time frame, I averaged nearly 20 more miles per tank full with the Lucas Upper Cylinder Lubricant in then the tanks without the lubricant in. At the time the price per gallon of gas was over $3 a gallon and the Civic got close ... MoreAbout 15 years ago I started using Lucas Upper Cylinder Lubricant in all my equipment and vehicles.

I did a random test of 3 tanks with Lucas Upper Cylinder Lubricant in and 3 tanks without. During the 5-week time frame, I averaged nearly 20 more miles per tank full with the Lucas Upper Cylinder Lubricant in then the tanks without the lubricant in. At the time the price per gallon of gas was over $3 a gallon and the Civic got close to 39 MPG. 1/2 gallon of gas per tank savings was $1.50 and 2.5 ounces of Lucas Upper Cylinder Lubricant cost me 45 cents or a tank savings of at least $1.00 per tank fill up. Since the Civic averaged over 25,500 miles per year, this would have been over $300 a year in savings. My second test was with a John Deere LT166 16HP lawn mower which I could mow our yard twice on 1 tank of gas and have about 1 inch of gas left in the bottom of the tank. When I added the Lucas Upper Cylinder Lubricant, I could mow twice on 1 tank of gas and have 2-3 inches of gas left in the tank. Although not sizable, there was a clear improvement with gas usage. The other benefit I noticed with the Civic was longer intervals between oil changes. I could run the Civic on synthetic oil for at least 9,600 miles before I would ever get an indicator on the dash informing me it was time to change the oil. Prior to the Lucas Upper Cylinder Lubricant, the average oil change indicator came on under 9,000. I use it in everything I own that takes gas or diesel.
Alcohol in gas is about the worst thing you can put in your system. We really dont have much of a choice anymore unless your willing to search out the "straight" gas pump station. Lucas fuel additive is my reasonable approach to conditioning the fuel system to minimize the effects of the ethanol. Its a fuel system lubricant to it adds a bit of protection to the fuel pump and also keeps the rubber components from becoming brittle and cracking. It also keeps the alcohol from attacking the exposed aluminum in the injection systems. I buy in gallons and refill my little one use bottles. I have 4 drivers in my family and I have them all adding a bottle at their fill ups. Been doing this for 4-5 years now. Upper head oiling to keep the piston rings and carbon deposits at ... MoreAlcohol in gas is about the worst thing you can put in your system.

Upper head oiling to keep the piston rings and carbon deposits at bay - I believe that claim too as I have scoped the cylinders at a plug change and was impressed with the tidiness of the combustion chamber. The cost of a bottle is cheap compared to the replacement cost of an in-tank pump. I consider this preventative maintenance.
Since June of 2014, I have a 2006 Dodge Sprinter 3500 diesel motorhome with the 2.7 liter, turbocharged 5 cylinder Mercedes engine.In June of 2019, I started using the Lucas fuel treatment and the motorhome had about 85k miles on it.I first bought the quart size of this Lucas fuel treatment because the quart size has ounce measurements on the side of the quart bottle. Now I buy the Lucas gallon size and refill the quart size from the gallon size.I was very lucky to be told to start using this Lucas fuel treatment, because in 2019, my injectors must have been clogged. This Lucas fuel treatment completely fixed the rough idling and rough starting. Improvement in the engine performance started happening on the first day, but it took 9 days for the Lucas fuel ... MoreSince June of 2014, I have a 2006 Dodge Sprinter 3500 diesel motorhome with the 2.7 liter, turbocharged 5 cylinder Mercedes engine.In June of 2019, I started using the Lucas fuel treatment and the motorhome had about 85k miles on it.I first bought the quart size of this Lucas fuel treatment because the quart size has ounce measurements on the side of the quart bottle.

This Lucas fuel treatment completely fixed the rough idling and rough starting. Improvement in the engine performance started happening on the first day, but it took 9 days for the Lucas fuel treatment to fully soak into the injectors and fuel system for maximum effect.Now my Sprinter runs great because of this Lucas, although I do change the engine air filter every 4000 miles, and I also clean the air filter at 2000 miles by blowing across it and dropping it repeatedly face down on the pavement.I order about 5 of the Mann brand air filters at a time from RockAuto.com because of RockAuto's low prices.Lucas fuel additive is the best thing that has happened to the consistent, exceptional performance of my Sprinter motorhome's engine.
Haven't had the need to use this since we sold our 82 75 series a few years ago, with 1.1m on the clock with almost factory compression. Since we bought a new Isuzu NPR 45-155 SWB, we started using this treatment again and managed to milk another 100ml pr 100 Kms and fuel efficiency. Only requires an approx 50ml squirt down the barrel before filling and Bob's ya uncle. Probably helps I don't drive like I stole it so injectors and pump on the cruiser were schmik with again, almost factory settings. If you've got an ear for a diesel tune and running vibe with a screw driver stethoscope, then try a before and after using about 1/2 a bottle and come up with your own conclusions. For me, I've got my way of doing things and getting good results. Good oil, scheduled ... MoreHaven't had the need to use this since we sold our 82 75 series a few years ago, with 1.1m on the clock with almost factory compression.
