I have a 1985 VT500. According to the cross reference I can use Mobil1 M1-104 filter. Switching to this filter would actually be much cheaper for me (Mobil 1 @ $10.84 vs Honda Dealer filter @ $22) and much easier to get (no need for a special trip to dealer).
My questions: Mobil1's site makes it pretty clear that using an automotive filter on a bike is not recommended. Why?
Also, what do forum member's suggest I use given the above information?
(btw, yes, this is related to my other thread on Oil choices but I thought I'd break out the filter discussion)
