Because of that I don't consider this a total validation of this mod. It is a very good sign though.

I'm about 500 miles from my 5000 mile oil change being due and I have only used 1 liter of oil. I've never had oil usage that low. Having the catch can allows me to recover oil that normally would have been burned, even with the PCV mod. Since the original mod doesn't call for a catch can I don't see how it really cuts down on oil consumption. I can say without a doubt putting a catch can in the system does.
