It seems that I've heard of the filter switch/no oil switch before. For better or worse here's my reasoning. And, yes, I'm coming from the perspective of track, not street: It costs me $27.00 to do a oil/filter change. ($15.00 for the Rotella and $12.00 for the K&N oil ,filter. I know the arguments concerning using Honda filters in lieu of aftermarket items, including those of good reputation, like K&N products. But that's a WHOLE OTHER topic. The K&N works just fine for me.) Add to that approx. $3.00 tax. For $30.00, give or take, and about one half hour's time, INCLUDING new safety wire for the filter, drain-plug and the plastic fill-hole plug, (I've done it to the point of being able to repeat it in my sleep) and I've got the peace of mind knowing that lubrication issues don't exist, even for the off times when I change the oil only (every other time). I know that the street is a whole other animal, BUT, the approx. 3k miles between oil changes (which is what I think most manufactures recommend) is still too infrequent IMO. When I rode "off track" I'd change it every 1500 miles...both oil and filter.
