Default OT - Why does gear oil stink?

No urgency here. Just wonder why gear oils are so stinky. Motor oil, while certainly no bouquet of roses, doesn't smell that bad. What gives?

Some are worse than others. I'd rather roll in cat poop than get a drop of Motul gear oil on me. That stuff is really nasty.

Don't know the answer to your question though.

Michael, you guessed just right.
Sulpur content is high PPM level in gear oil.
It slowly converts to H2S (the cat ... smell) during the deterioration of the structure of the oil (time & heat cycles).

I second Geo, I would rather shower in my cat's kitty litter than have to change my gear lube again!

Hehe...true story:
My bro-in-law changed his tranny oil in my garage in his MR2. He wasn't careful in putting the un-used bottles back, but was kind enough to put my wife's car back in the garage.

The next day, Mrs. Z-man runs over a bottle of that stuff, squirting it all over the place. The garage must have smelled for at least 1/2 a year!

I think is might be a blend of camel dung and mucus from daycare centers in the middle east.

Have you ever had that stuff spill on your person? YUCK. It does NOT wash off! It has to slowly wear away.

Nothing smells as good as Castrol R, made of vegetable oil. Old racing bikes running it smell like french fries.

Oh yeah, that stuff gets rancid and stinks even worse than regular gear oil though. Starts to smell like bad fish.

I tell ya though, as soon as I open a container of gear oil my eyes start to burn. I can tell if a bottle of the stuff has been opened in a room even hours later, even if none of it has been spilled. Part of the reason I stopped wearing contact lenses, my eyes are just to sensetive to stuff like that.

Oh yeah? Well not if you change it after every race like you're supposed to. Or were you talking about your fish and chips oil?
