lately ive been thinking about investing in a stainless steel reusable oil filter because doing oil changes every 7 hrs is getting pretty pricey. believe me i understand the whole " oil changes are cheap, motors are expensive " expression, but im a college kid on a semi-limited budget so im trying to cut costs when i can. but have a couple of thoughts about these stainless filters. - do they filter as well as the K&N paper filters i currently use? - have you ever had an issue running one of these filters? - which brand of filter should i buy and which should i avoid? thank you in advance!
