I'm practically brand new here, and everyone's been awesome so far, so thanks ahead of time.
I drive almost 600 miles a week, on and off driving, delivering pizza. I'm sure this is gonna take a toll on my baby (07 wrb wrx with 120 miles!) Are there any precautionary steps i can take to maintain her integrity with so much wear over such little time? More specifically:
How often should i change my oil? what type of oil should i use?
How can i get the best gas mileage while still having some fun? heh
And lastly, will getting mods like the cobb AP, etc. help or hurt my car in the long run?
