I have a 2005 Rav4 stk shift. Everytime I drive it, my hands always smell like gasoline from the stick shift ---WHY?????
Time to clean it with some 1/3 ammonia 2/3 water solution. It probably from all the years of shifting and hand grease build up.
Or change the know with a new one that is metal. Although that does get cold in the winter, not sure where your location is .
