First of all welcome! Please look upon my post as advice and not a call out.
I know you didn't ask this but I have to say that motor oil has no use on a bicycle. It's too thick for chains,cables and shifters and it's too thin for cranks and wheel bearings. Leaving excess lubricants on external parts can only introduce dirt into the internal surfaces you're trying to maintain. So clean the parts before and after applying the proper lubricant.
