MG421-8 microGreen Oil Filter
The microGreen® oil filter is the most advanced technological leap in engine filtration in 30 years. It replaces a conventional oil filter assembly without requiring any modifications to the engine or filter housing. By continuously filtering a small portion of the engine oil through the patented microfilter system, the microGreen® filtration system allows your vehicle to operate up to 30,000 miles without changing the engine oil.
