I dont know if would want to double oil change intervals. Even if the oil is that much cleaner what about fuel dilution after bombing? I guess its still a good idea to get the one micron filtering and change filters at 4000 miles. PS some heavy equipment, Loaders ect. have oil bypass systems from factory so I guess it works. Does anyone know how well the Fleetguard stratapore filter works in microns. I didnt see any micron info on the fleetguard site. Anyone have any thoughts on this??
