UCL – Upper Cylinder Lubricant Top Lube

The Rislone UCL additive is specially designed to lubricate the upper cylinder of an engine; however, this action starts in the fuel tank. This UCL formulation helps overcome the lack of lubrication in modern fuels including unleaded Pterol, ULSD diesel fuel, E85 Ethanol, and other oxygenated and biofuels. In the fuel tank, UCL helps prevent rust & corrosion and this process continues into the fuel lines. UCL also lubricates and protects the fuel pump, giving it a longer life and quieter operation. The next step for the UCL formula is to lubricate the injectors, allowing them to work more efficiently. Not only are cylinder deposits cleaned, including gum and varnish, but as the UCL treats the upper cylinder, the lubricating film helps to prevent carbon from sticking so that it can be burned. This film completely lubricates the upper piston, rings, guides, valves, and seats.

Directions / Dosage:

Gently tip the bottle and completely insert the neck into the fuel tank opening, allowing the entire contents to empty into the tank. Twist and gently pull to remove.

One bottle is concentrated to treat up to 20 gallons of Pterol or diesel fuel. For larger vehicles use 1 bottle per 18 gallons of fuel capacity, or 1 ounce per 3 gallons. Small engines use 1/4 bottle for every 5 gallons.

In vehicles with known fuel lubrication problems, double the dosage.

Results will either be immediate or noticeable within a few days of driving.
