Abstract
A lubrication system having an oil filter modified to replace or supplement the performance of lubricant additives that may be used within an internal combustion engine to increase the performance of a lubricant. The formulation of the lubricant is changed in accordance with the chemicals placed in the oil filter. For example, when the oil filter contains a strong base, the lubricant concentration of detergent will decrease, in some cases to zero, while the dispersant concentration in the lubricant will increase. The resultant closed system allows the oil drain intervals to be significantly extended.
