Just did a couple of oil changes (my 9 and another buddy's 9) recently. This is going to sound wierd, but one of the brands of oil, right out of the bottle, smelled GHASTLY, almost as bad as hypoid gear oil. The other emmitted almost no odor... maybe a slight hint of banana smell. Both are motorcycle-specific 10W-40 dino oils. My buddy said, "That oil smells like it went bad!" I know oil doesn't go bad in the container, but what would make it smell so bad... sort of a gasoline smell.. as I mentioned, closer to the nasty hypoid gear oil smell. Any thoughts? Thanks in advance, RT.
