Microgard MGL51356 cut open off my parents 1997 Mazda 626 2.0 I4. Filter has been on there about 3.5 years and 1000 or so miles. Lots of short trips and very infrequently driven the past couple of years. Changed oil after putting new radiator,hoses,thermostat and temperature sensors in getting ready to sell it. Replaced with Champ oil filter.
