A cleansing oil filter includes a housing, a porous filter element disposed in the housing, and a quantity of liquid antioxidant/additive solution in the housing associated with the filter element. Preferably, the filter contains at least 10 ml of antioxidant, and more preferably, between 20 and 100 ml of antioxidant. A substantial quantity of the liquid antioxidant/additive solution is available for immediate release when oil flows through the filter. A method of converting an internal combustion engine from a petroleum-based lubricating oil to a botanically-based lubricating oil involves draining a petroleum-based lubricating oil out of the engine, removing an oil filter from the engine and replacing it with a first cleansing filter having a quantity of liquid antioxidant/additive solution therein, adding a first batch of a botanically-based lubricating oil to the engine, running the engine until warm, and replacing the oil and filter a second time using botanically-based oil.

The method of claim 1, wherein said botanically-based oil comprises an oil selected from the group consisting of vegetable oils, canola oil, corn oil, cottonseed oil, olive oil, peanut oil, sunflower oil, safflower oil, and mixtures thereof. 3. The method of claim 1, wherein each of the first and second cleansing oil filters is the oil filter of claim 1. 4. An internal combustion engine system comprising an internal combustion engine, a quantity of botanically-based oil for lubricating moving parts in said engine, and a filter for filtering particulate matter from said botanically-based oil, said filter including a liquid antioxidant disposed in the filter so that said botanically-based oil comes into contact with the antioxidant during operation of the engine. 5. The internal combustion engine system of claim 4 wherein said botanically-based oil comprises an oil selected from the group consisting of vegetable oils, canola oil, corn oil, cottonseed oil, olive oil, peanut oil, sunflower oil, safflower oil, and mixtures thereof. 6. An internal combustion engine system comprising an internal combustion engine, a quantity of botanically-based oil for lubricating moving parts in said engine, and a filter for filtering particulate matter from said botanically-based oil, said filter including a liquid antioxidant disposed on or in a solid carrier disposed in the filter so that said botanically-based oil comes into contact with the antioxidant during operation of the engine. 7. An internal combustion engine system comprising an internal combustion engine, a quantity of botanically-based oil for lubricating moving parts in said engine, and a filter for filtering particulate matter from said botanically-based oil, said filter including an antioxidant disposed in the filter so that said botanically-based oil comes into contact with the antioxidant during operation of the engine, wherein said antioxidant is selected from the group consisting of phenolic compounds, arylamino compounds, substituted thiazoles, substituted thiadiazoles, phosphosulfurized olefins, zinc dithiophosphates, and zinc dialkyl dithiophosphates, aromatic sulfides, aromatic polysulfides, alkyl sulfides, alkyl polysulfides, sulfurized olefins, sulfurized carboxylic acid esters, and sulfurized ester-olefins, and mixtures thereof.
