It cleans and lubricates the entire fuel system, improves fuel economy, boosts power, neutralizes harmful contaminants, and protects against rust and corrosion. Compatible with a wide range of vehicles, it delivers noticeable performance gains and longer engine life with every use. ## Description 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. 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. 5.25oz Bottle - One bottle treats up to 25 gallons of fuel. 1 Quart/32oz Bottle - One bottle treats up to 100 gallons of fuel. 1 Gallon/128oz Bottle - One bottle treats up to 400 gallons of fuel. ## Features - The world’s #1 fuel additive for both gasoline and diesel engines - A great tune-up in a bottle – treats gasoline, diesel fuel and increases MPG - Cleans and lubricates the fuel system, including fuel injectors, carburetor and combustion chamber - Improves fuel economy by burning excess exhaust emissions - Increases power and acceleration by improving fuel flow and reducing deposit buildup - Neutralizes sulfur and other harmful contaminants present in the fuel system - Increases the life of pumps and injectors - Prevents rust and corrosion, prolonging the life of engine and fuel system components - Complies with federal low sulfur content requirements for diesel motor vehicles and non-road, locomotive and marine diesel equipment engines - Safely replaces the need for lead in older engines without causing harmful effects ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000ARPVOI | | Best Sellers Rank | #86 in Automotive ( See Top 100 in Automotive ) #3 in Diesel Additives | | Brand | Lucas Oil | | Brand Name | Lucas Oil | | Container Type | Bottle | | Customer Reviews | 4.8 out of 5 stars 24,397 Reviews | | Global Trade Identification Number | 00049807100032 | | Included Components | 1x 1 Quart bottle | | Item Type Name | Fuel Injtr Cleaner | | Item Weight | 898 Grams | | Liquid Volume | 1 Quarts | | Manufacturer | Lucas Oil | | Material | Plastic | | Model Number | LUC10003 | | Number of Items | 1 | | Package Information | Bottle | | Part Interchange Info | 10003 | | Part Number | 051-587 | | UPC | 049807800031 049807400033 049807100032 | | Unit Count | 32.0 Fluid Ounces | | Warranty Description | 30 Days | ## Product Details - **Brand:** Lucas Oil - **Liquid Volume:** 1 Quarts - **Package Information:** Bottle - **UPC:** 049807800031 049807400033 049807100032 - **Vehicle Service Type:** Car, Truck, Motorcycle, ATV, Boat, Lawn Mower, etc. ## Images ![Lucas Oil 10003 Fuel Treatment - 1 Quart - Image 1](https://m.media-amazon.com/images/I/616euPEi4YL.jpg) ![Lucas Oil 10003 Fuel Treatment - 1 Quart - Image 2](https://m.media-amazon.com/images/I/61vQUf40JYL.jpg) ![Lucas Oil 10003 Fuel Treatment - 1 Quart - Image 3](https://m.media-amazon.com/images/I/81LuFRhUHdL.jpg) ![Lucas Oil 10003 Fuel Treatment - 1 Quart - Image 4](https://m.media-amazon.com/images/I/81mEYRJiobL.jpg) ![Lucas Oil 10003 Fuel Treatment - 1 Quart - Image 5](https://m.media-amazon.com/images/I/81lj2Vje3vL.jpg) ## Available Options This product comes in different **Size, Number Of Items** options. ## Questions & Answers **Q: Will gas mileage increase** A: I drive (and now use this in) a 1996 Toyota 4Runner. Prior to its use I'd averaged 17mpg, then performed a replacement on plugs, wires, and air filter (upgrading to a K&N); in addition to cleaning the MAF and throttle body (all on my own, mind you!). I now average anywhere between 19.5 (city) and just under 25 (highway). I'm not sure just how much of a fuel increase can be contributed to this product, but I no longer go without it! **Q: Would keeping this in the car in hot Texas heat be an issue?** A: OF COARCE ITS A DANGEROUS ISSUE !! Storing any flamable liquid in a car is very dangerouse , especially a hot car !! you put yourself at risk of combustion from the heat & also combustion if you get in a accident !! buy a tiny bottle of lucas fuel additive , its about 5.5 oz.s !! fill that up and insulate it in trunk to keep it cool . then when you fill up ? you will have a bottle ready to put in your tank !! instead of hauling around a gallon of the stuff . **Q: Whats difference between this and the fuel treatment 5 oz** A: Their is no difference other than the packaging **Q: Will it help remove P0420 code?** A: 2 bottles of Lucas oil, one gas refill apart, helped with my P0420 Code on Infiniti QX60 engine light. With the 2nd bottle, the light was gone. It worked like a charm. I will continue to keep the fuel tank clean moving forward. Tip : don't wait for the fuel tank to be completely empty before you refill. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***D on January 24, 2026* ### ⭐⭐⭐⭐⭐ Review *by J***I on February 5, 2026* ### ⭐⭐⭐⭐⭐ Review *by T***N on January 22, 2026* ## Frequently Bought Together - Lucas Oil 10003 Fuel Treatment - 1 Quart - Lucas Oil 10130 Pure Synthetic Oil Stabilizer - 1 Quart - Lucas Oil 10512 Deep Clean Fuel System Cleaner - 16 Ounce --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/4988471-lucas-oil-10003-fuel-treatment-1-quart](https://www.desertcart.fr/products/4988471-lucas-oil-10003-fuel-treatment-1-quart) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-05-01*
