Lubricity is the measure of how much a lubricant reduces friction and/or wear and tear on components of, in this case, your engine and fuel system. When lubricity is too low, the components rub together with more force (friction) causing increased wear and damage, resulting in premature parts replacement and higher services costs.

As fuel pressures, running temperature, and performance of engines has increased, so has the need for higher lubricity to ensure that all the required components operate at full efficiency.

Adding the recommended amount of Fuel Doctor to your fuel will ensure you have a high level of lubricity in your fuel system which can extend the life of those components.
