^^^^this^^^^only way for gas to really get in the crank is bad piston rings. Its getting some serious blow by
That does sound like a BS answer. But if it makes you feel any better (and I preface that I'm no gear head and barely know what I'm talking about) but I smell gasoline in my oil when I do oil changes. It does bother me a little.Am I the only yamaha owner with fuel getting in the oil? They said the cause could be that I only drive it a half mile at a time. BULLSHIT. I've had four fourwheelers over the past thirty years, and used them all for the exact same thing, and never had a problem.
