[QUOTE="RossKean, post: 1455901, member: 19880"] Finer media will normally require higher pressure to maintain the same flow rate [U]for a given media type[/U] but the bypass valve in a filter should be designed to accommodate back-pressures expected for the filter medium. Purolator's statement about "bikes vs vehicles" is meaningless. There is no reason why an FJR's oil pump can't get oil through a filter and even if it couldn't, the filter bypass valve wouldn't be activated. If a proportion of the oil bypasses the filter sometimes at high RPM, it really doesn't matter as long as most of the oil goes through the filter most of the time. (If a contaminant particle misses the filter this time, it will get caught the next time.) If the filter is clogged and on effectively permanent bypass, that's an entirely different situation. I highly doubt that Purolator's filters are significantly different from other "premium" automotive filters from Mobil, Bosch, Quaker State or even Fram in terms of resistance to flow through the medium (back-pressure). I have been using automotive filters (mostly Mobil) on two different FJR's for close to a half million kilometers without incident. YMMV. [/QUOTE]
