An engine system includes a concentration determination module and an additive dispensing module. The concentration determination module determines an amount of an additive in at least one of an oil system of an engine and a fuel system of the engine. The additive dispensing module dispenses a supplemental additive into at least one of the oil system and the fuel system when the amount of the additive is less than or equal to a predetermined amount.

Systems and methods for dispensing oil and fuel additives

In one exemplary embodiment of the present invention, a fuel stabilizer system is provided. The fuel stabilizer system includes a fuel additive storage unit that stores fuel stability fluid. A fuel stability fluid supply system supplies fuel stability fluid from the fuel additive storage unit to a fuel storage unit. A control module estimates an age of fuel in the fuel storage unit and selectively controls the fuel stability fluid supply system to supply fuel stability fluid to the fuel storage unit based on the age of the fuel.
