My vote is for the gas. I'll bet anything you're not using premium fuel. I had always used premium fuel in everything. Then about 10 - 15 years ago, I read a consumers reports mag. article saying that one does not need to spend the extra $$$ for premium. So I switched - to regular Shell in a Mazda that called for 87 octane. Within a tank or so, I could smell the sulphur. So I switched back to premium, and it went away.
