Product Details
Fuel quality varies more than most people realize, and lower sulfur formulations in modern fuels can leave upper cylinder components without the lubrication they need. Lucas Upper Cylinder Lubricant and Fuel Injector Cleaner addresses that gap with a solvent-free blend of oils and high-detergent additives that clean and protect the entire fuel system.
One quart treats up to 100 gallons of fuel at the recommended dosage of 2 to 3 ounces per 10 gallons. That makes this a cost-effective option whether you are running it in a daily driver, a diesel truck, or seasonal equipment. The formula works in both gasoline and diesel engines, cleaning fuel injectors while lubricating upper cylinder walls, pumps, and valves. Lucas specifically designed it to compensate for issues caused by low-sulfur and reformulated fuels.
Pour it directly into the fuel tank at fill-up and drive as normal. There are no solvents in the formula, which means it cleans through detergent action rather than chemical stripping — a gentler approach that is safer for fuel system seals and O-rings over repeated use.

good stuff
I had an old IH 1066 that sputtered after 6 months of inactivity. Before I tried to replace the fuel filters, I decided to give this stuff a try. After only a few hundred yards of pulling a 21 ft disc the sputtering stopped and there wasn' t a bit of black smoke coming from the stack not to mention a lot more power. It really sold me on Lucas products. I now use it to spice up all of my Ag fuel. I notice that I no longer have condensation problems in any of my fuel tanks and it seems I get a lot more power and use less fuel. I'm impressed and it's hard to impress this old Missouri farmer.
