I have always wondered what use and benefit there was when using an upper cylinder lube. Now you've suggested a benefit and you seem to stand by it even when questioned by
@OVERKILL. Great. It sounds like you know something I don't.
Please tell us how you've arrived at your conclusion. You said "
UCL reduces blow by and threfore causes better throttle response". Have you some data that backs up your assertion or are you making some assumptions? How do you know UCL reduces blowby? And how do you know that, if true, reduced blowby causes better throttle response? Have you seen some test results or is your conclusion based on personal experience or, perhaps, assumptions?
I'm looking foward to your response. I'd love to be convinced that UCL has real-world benefits.
