Oil Change Issue.

[Twistoffate0817]

Hello, Well i hit 1300 miles so i decided to get my oil changed, because i was told to change it after the first 1000 miles. So i did today. I went to the dealership to get the oil changed, due to i wanted them to check other things as well. So I asked for synthetic oil, and i was basically told i was nuts. That i did not need it, why even get it, blah blah blah. But i got what i wanted. They charged 61 dollars for it and i was like UHM wow. Is that a normal price for synthetic oil? Also, When do i get my oil changed again now? I only put 1300 miles on my yaris within 5 months, so do i wait another 5 months or until i hit ANOTHER 3000 miles? Im so confused.
