<VV> Re: oil filters

[Bruce Schug]

I wonder if one could run a car for a set period of time under set 
conditions with a particular oil filter, then drain the oil and send a 
sample away to one of those labs that test your oil for a few bucks. 
Then fill it up with oil and do the same thing with a different filter.

Short of having a highly sophisticated lab set-up, would this be a 
fairly valid way to evaluate filters?
