Hello I will help you,
If the hood does not pop up or the hinges are sticking a little white lithium spray grease will free them and restore smooth operation.
Most power steering fluids are petroleum
based but there are some on the market that are glycol based and some synthetics. Transmission fluid is typically petroleum based but again there are some synthetics.
If you have a specific concern I can make a reccomendation.
If I have answered your question please "ACCEPT" this answer so that I may be paid
Thank you
