You know, you might be on to something there. One of my motorcycles is an oil burner - it's a known issue - Yamaha bored the cylinders slightly oval - whoops! This makes for lots of blow-by so I use Rotella to keep things as clean as possible - especially the rings - stuck rings would only make the situation worse. That's right - diesel spec oil in a 12,000 rpm engine. Well one day I got a wild hair up my *** and decided to try Mobil 1. My oil burn rate went up 500%. So back to Rotella I went! Oil consumption went down to normal. Not saying this is true for the VX but that's my experience with synthetic oil and an oil burning engine...
