Hi all, i have a 2004 DYT4000 with a 18.5HP B&S engine, has a oil filter, and i have been buying the black oil filter from sears, but at like 11.99$ i would rather use like a M1-102 or a small filter of that nature, but i have NO idea of what filter has the same flow rate, and drain valve or not as the OEM one from sears. Does any one know what filter would work on this tractor with out any ill affects? Thanks.
