Still, whatever floats your boat.
What less costly filter filters just as well?
A quick use of the advanced search function revealed a 12/6/09 thread, from which I have copied the following from a couple of posts by river_rat:
PureOne 99.9% at 20 microns (multipass test)
Purolator Classic 97.5% at 20 microns (multipass test)
Ecore (Champ, STP, ValueCraft, Supertech) 94% at 20 microns (multipass test)
Toyota TRD (#PTR43-00080) 98% at 20 microns (test unpsecified)
Mobil 1 Ext...Performance 99.2% (microns unspecified, multipass test)
Bosch Premium 99.9% (nothing else specified)
K&N 99% "of harmful particles" (nothing else specified)
Rousch 99.2% (nothing else specified)
and
Fram Extra Guard 95% (microns unspecified, multipass test)
Fram Tough Guard 99% (microns unspecified, multipass test)
Fram Extended Guard 97% (microns unspecified, multipass test)
I know that this is hardly exhaustive data, but it appears that either the Fram TG, the Purolator P1 or the Bosch Premium would filter just as well as an M1 oil filter. Among these, the P1 is little more than 1/3 the cost of the M1, plus Purolator has a nice MIR available knocking $3.00 off the cost of up to four P1s.
