Abstract:
A method of converting an internal combustion engine from a petroleum-based lubricating oil to a botanically-based lubricating oil, comprising the steps of:a) draining a petroleum-based oil out of the engine; b) removing an oil filter from the engine and replacing it with a first cleansing oil filter having a quantity of liquid antioxidant/additive solution therein, a substantial amount of said liquid antioxidant/additive solution available for immediate release when oil flows through the filter; c) adding a first batch of a botanically-based oil to the engine; d) running the engine for a predetermined time period; e) shutting the engine off; f) draining the first batch of botanically-based oil out of the engine; g) removing said first cleansing oil filter and replacing it with a second cleansing oil filter having a quantity of liquid antioxidant/additive solution therein, a substantial amount of said liquid antioxidant/additive solution available for immediate release when oil flows through the filter; and h) adding a second batch of botanically-based oil to the engine.
