*I know almost nothing about cars, please bare with me 
*
Questions:
1. My parents have always told me since I was a kid that stepping on the gas would wear the engine down a lot. Is there something I can get for my engine to prevent the wear?
2. Should I get a used Civic Si or a new? I'm looking around and a used with about 50k miles on it is about 15-18k while a new is around 23k.
3. Are there any simple maintenance I can do to my car myself?
4. Any other suggestions please.
Thanks for your time.
