5000 miles is perfectly fine. A lot of people in this
thread had their first oil change at 5000 miles.
I'm going to be bringing in the car for its first oil change in the next week or so. I currently have 7100km on it which is approximately 4400 miles. I'll bring it in at around 5000 miles and then get the oil changed every 4000 miles afterwards. My oil life indicator currently says the oil life percentage is 30%, but I'm not sure whether to trust it or not.
