If you use synthetic, yes. But organic or semi-synthetic oil will break down faster in a high-compression high revving engine. So it's up to you. If you only keep your bike for a few seasons and buy a new one, then it really doesn't matter. Also, if you're racing a lot, you'll definately want to change your oil much more frequently.Originally posted by kpt4321
Don't you think changing your oil every 1500 miles is pushing it just a little bit?
The whole point is that the Scott's is laser-perforated stainless steel filter medium, versus paper glued to cardboard that Fram uses (it's -literally- paper glued to cardboard...take a Fram filter apart sometime). With the laser perforated SS mesh, all the filter holes are exactly the same diameter, so it doesn't lose filter efficiency when some holes get clogged with smaller particles (paper filters lose efficiency because the holes are organic and non-uniform in size, and the smallest holes get clogged with filtered particles first, leaving only larger holes for the oil to filter through, which allows more and more larger particles through as time goes on). So...It's good for me.Originally posted by ninjakid04636
just for piece of mind, i prefer replacing my filters at every oil change
I've never heard of the mesh getting damaged...it's pretty frickin beefy. As for clogging up...the Scotts filter has more filter holes than a standard paper filter, because the holes are smaller, on average. So if the filter will get clogged, a paper filter would clog first. As long as you clean it right, it's completely unclogged and refreshed before you put it back into the bike after each change. Also, the magnet in the filter is in the pre-filter, right before the filter medium, so it catches the big particles before they hit the filter, versus the oil pan magnet that just catches particles floating around in the pan. The magnet in the filter helps keep the filter cleaner, and keeps some of the tiny little bits as far away from the engine as possible.Originally posted by helo-pilot
mabe yall can explain this to me. the filter has a strong magnet inside of it,(or so im told). what does this pick up. that a magnetic drain plug wont. it double security, but im curoius. my other question, is that there is a bypass valve in the motor so that if the oil has i hard time getting through the oil filter, it can bypass it and that way the motor wont be starved for oil. do these filters seem to get cloged easier, faster, etc. so that the oil ends up going throught the bypass? it would seem that this could be an issue since it is suposed to let less particals through. and lastly, has anyone ever heard of one of these filters getting messed up, like where the filter its self got dammaged. like the mesh inside got torn?
Thing is...the Scott's filter's holes are ALL 35 microns. Nothing bigger than that gets through. The normal paper filters have grossly uneven filter medium, and while some of the holes may filter 12 microns, what happens when they get clogged? You really have to look at the average micron filtration, which is really difficult to measure because it depends largely on how long you leave the filter in the vehicle between changes, but almost all paper filters have an average filtration of 32-38 microns, 32 being some of the highest quality filters available. And you figure, if this is an average number, and they're filtering down to 12 microns, how big are their bigger holes? What are they letting through? So while the Scott's lets a higher number of small particles through, it lets a lower number of larger particles through (lower, in this case, being 0). The Scott's doesn't let anything bigger than 35 microns through, ever, and really, it's the big guys you want to look out for anyway. Also, it takes a particle bigger than 42 microns or so to actually do anything bad to any engine internals. I wish I could remember where I got this information so you (and me) could double check the accuracy of everything, but I can't remember exactly. It was a research project someone did for their masters in some specialized mechanical engineering study, and they had all sorts of references and test datum.Originally posted by SubHuman
The Scotts filter doesnt filter worth a shit. 35 microns is all and I know for a fact Wix filters down to 12 microns. Although I would probably use one over a junk Fram. They are intended for race bike which change their oil obsessively and rebuild their engine more regularly. Filtermag's work well for getting the really small particles that the filter cannot filter.
