Hey all I have seen and read a few different articles i am sure this has been addressed before but cant get a firm answer. So..... I ALWAYS use the oilfilter from the dealer however this time it did not have the bmw logo on it and looked alittle different i went on a quick ride no issues at all. My question is i have heard of and seen guys using car filters on their bikes, how much different is it? There are alot that fit my bike and are few dollars cheaper, would it hurt the bike to use a quality car oil filter? Can some one explain the diff? Is it pressure? Also not to start an oil thread but is it true u are to use conv oil first 8000 miles or can i switch to syn?
