Re: What type of oil filter do you use?
My bike is still new, so I've only had the 1st service where the dealer changed oil so far. Next change I'm putting on an Amsoil EaO filter with synthetic nanofiber filter element. I've read some concern about previous Amsoil filters which, although good quality, had a fairly small filter element surface area which might plug quickly. The new EaO filters, however, have more of a 3-dimensional filter element volume which can apparently hold a ton of particulate matter without plugging, and also filters exceptionally well, even down to particle sizes that go right through most other filters.
I saw on another forum (sorry, don't remember which one - just happened across the post while searching for info about the EaO) that a guy did an oil analysis on the clean oil BEFORE putting it in the engine, and then later when he changed it. Using the EaO filter the used oil apparently had a LOWER particle count than the clean oil (!). If that's true - wow! If not, I've still heard enough good (and nothing bad) about the EaO filters to use them anyway.
The one for the EX500 is the EaO103.
On Fram filters - I also belong to a tractor owner's forum inhabited by farmers and acreage owners that generally have lots of engines to maintain and the consensus is the same over there - Fram is junk. Someone over there even heard that at one point Dodge was denying warranty claims on their Cummins deisel engines if they found a Fram filter on them. Don't know if that's true or not.
