I don't go around sniffing it and am not about to use it as an aftershave, but I'm not repulsed by it either.
One of my worst experiences with it was picking up a trunk load of transmissions in my Lincoln, and one had been filled with gear oil. They all had been drained, but the gear oil one still had some leaking out and despite having them all bagged as well as on cardboard, I still managed to get some gear oil somewhere in the trunk. I think that stuck around for a couple of months, and in fact didn't really go away until summer "baked" it out.
