The IOLM will turn on the light after 1 year. It also uses computer algorithms to analyze factors related to driving style and conditions. If you wanted to to be absolutely certain, you could get the oil analyzed. At your rate of mileage build, it might take you another couple of months to reach it, at which time your oil starts getting on 1 1/2 years old.
If I were in your situation, I would probably change it in order to have no questions about your maintenance diligence if a warranty situation arose.
