I am using synthetic oil, currently Mobil 1, 0W-40. I probably will
follow the manual, which I think says 7500 miles as oil change
interval. I am not sure changing the filter more often would change
anything, as it does not seem like the filter gets loaded to capacity.
For my skiing vehicle, a 1996 Bronco, there are currently filters like
Ultraguard Gold, Mobile 1, K&N that has superior flow, and multiple
pass particle trapping efficiency better than that of an original
Motorcraft filter. These are probably inferior to the fleece filters
made by Mann for Mercedes, but still an improvement.
I was simply wondering whenther anybody knows about a supplier that
makes BMW filters in a material superior to paper.
Probably the OEM paper oil filter is sufficient for longevity, engine
oil that doesn't get loaded with soot, and stays light simply appeals
to the perfectionist in me.
