I am thinking the OP needs a friend to help out with basic car stuff, I guess if you don't know, you don't know, dealers would have a field day with you fella.
I am sure you have a friend or family member that knows about cars or maybe someone local here who could steer you and help you learn the basics.
I guess this is why some basic stuff is part of the driving test these days.
