Ive used it in the crankcase, throttle body and gas tank. Its made from petroleum products. No issues yet. I have also used Sta-Bil Marine to counteract the Ethanol in CA gas.

Theres really no need to put any in the crankcase with todays oils. The detergants that are in modern oil keep the internals plenty clean enough. Now if your running a non-detergant oil and don't change it often enough thats another story.
