Ive heard for years that oil lowers octane and introduces knock, however not a single person/forum could provide definite numbers. I used to consistently get about 1-3 degrees knock randomly all over the rpm range & Ive always had a moderate bit of blow by esp since modified. Last weekend i decided to install the Crawford AOS to completely eliminate the stock system. Cleaned out my intake pipes and fmic with gas and water. Since then I have driven aggressively, with little mechanical compassion in an event to purposely introduce knock however my iam is a solid 1. Not a single knock event. Intake pipes are now bone dry. My take is that oil in the intake significantly introduces knock. My engine even sounds so much better and revs are much smoother and of course idle is DEAD quiet & stable.

Ive cleaned my intake a few times but it comes back on the next boost session. Since the AOS it has been completely dry. By now my engine bay would be covered with a film of oil due to bov venting. I guess i have above avg blow by, but i also hit over 20psi often.
