How high up on the dipstick is it? As it's fuel injected it's hard to see how gas would get into the crankcase. Get them to do a compression test in case the piston is cracked.

Are you under warranty? If so the Dealer has to make it right even if they have to replace the engine.

^^^^this^^^^
With fuel injection it's really hard to flood the engine and get gas in there.
Any performance loss?
How did you discover this?

And of course don't drive it till you change that oil...

****.. just pull out the dipstick and put a lit propane nozzle down there... that'll get rid of all that pesky gas in there.


Quickly! :D

So the injector was leaking fuel into the cylinder? Hope so as that's an easy fix!

Dec 22 2016. Connecting rod came through the crankcase. The gas in the oil problem has never been solved. AM not happy to say the least. We'll see if Yamaha warranties this if not will sue for damages. I would like to trade it off, but can't legally do so without telling buyer of the problem, witch makes it not worth much. I got seriously SCREWED.

My brand new 2016 Viking would almost always take 2 tries to start when cold and I also had gas in the crankcase. Turned out to be a loose spark plug wire at the plug. Firmly seated the boot and ran much better. I may add I was not getting a red hot exhaust like everyone else until I fixed the loose spark plug boot.

Need input

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.

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.

Yamaha won't admit there is a problem. So I fixed it myself. Bought a HOnda 1000. Took a beating , but was the only solution, goodby POS Yamaha.
Dang man. Guess I can't blame you. You should have looked into those new Yanmars. LOL.
