Lucas Oil 10003 Upper Cylinder Lubricant and Fuel Treatment - 1 Quart

Lucas Oil Upper Cylinder Lubricant and Fuel Treatment is a concentrated fuel additive designed for both gasoline and diesel engines. This alcohol-free, solvent-free formula addresses the lubrication deficiencies created by modern low-sulfur diesel and reformulated gasoline fuels.

Key Benefits:

• Restores lubrication properties removed from modern fuels during refining processes
• Increases fuel economy—savings often exceed the cost of treatment
• Reduces harmful emissions while increasing combustion efficiency
• Lubricates rings, cylinder walls, valves, pumps, carburetors, and injectors
• Extends engine component life through enhanced lubrication
• Increases power output and throttle response
• Essential protection for rotary injection pumps
• Safe lead substitute for older engines requiring valve seat protection

This fuel treatment works by replacing the polymers stripped from fuels during emissions-focused refining. The result is a slicker, more powerful fuel that provides superior lubrication to critical engine components while delivering cleaner, more complete combustion. Compatible with all gasoline and diesel engines, this quart bottle treats multiple tanks depending on your fuel system size.
