Yes, having my 25,000 mile oil change intervals do justify higher oil costs per quart. It is much much cheaper for me since I only have to change my oil once a year. And yes, you have the oil analysis that shows that this is perfectly fine. Plus I don't throw out gallons of good oil a year.

You say you do lots of research.. Then you would know that in EVERY study shows that a K&N on average lets in more dirt than a foam or stock filter. You may not show much dirt in your oil, but if you ran one of the others you would show less dirt or oil.

You only selectivly use what research or facts you agree with and toss out the others.
