Oil High is not a good sign, bring the car into the dealership for check-up. Oil Change is calculated against 15,000 mile intervals usually, it doesn't go faster if you drive faster. The only thing that may change is when you top off the car's oil with an additional liter of oil, it will tell you to do so. It's possible I suppose you drove hard and for great distance and it so happen to reach the mileage to send a warning to do an oil change. OR the oil change symbol simply shows up because you have the Oil Level too High.
