actually guys i just remembered that my fuel pump broke not to long ago like around the time this heating started and i never changed my oil. i went to pull out the dip stick and i wiped it with my fingers and its and the oil just ran down my finger and hardley felt like oil more like a watery oil. (and the oil color is normal). it also smells gassy, can the fuel mixture in the oil lower viscosity (of course)? and can this cause overheating?
