How to express the place where I can fill up the car? Can I say "Oil station"?

I have learnt one new sentence and some phrases yesterday.

Sentence:
"Don't try to understand a girl completely, if you do, then ever you'll go mad or you'll start loving her."

Phrase:
1. fill up the car
2. fill her up
Question: How to express the place where I can fill up the car? Can I say "Oil station"? American English = Gas station.  British English = Petrol station. 

If you want to give your friend "加油" (jia1 you2)??, you can use the following words to express:
1. Go!
2. Go for it!
3. Come on!
4. Hand your up.?? (maybe it's incorrect. It's usually means you must be relax and have a rest = Put your feet up. .So please tell me which one is correct. what's the correct answer?)
