I'm contemplating installing a Fram Ultra Synthetic (XG) filter. Fram specifies a shorter filter for my application (different model number in the PH series), but this XG filter has the same threads and a similar bypass setting. 1. Are Fram XG filters restrictive to flow? Some have suggested the high efficiency rating leads to flow restriction, while others say the synthetic media makes it easy-flowing. 2. Is it a problem that the bypass rating of the Fram XG is slightly higher than that of the OEM filter I plan to replace? Is this problem mitigated or exacerbated by the Fram XG's flow properties. 3. As the Fram XG filter is designed for a long OCI, are there any drawbacks (besides the price) to using it for short OCIs? Someone suggested that it may sacrifice fine filtration at the expense of high capacity, but I've seen other reports to the contrary.
