Synthetic oic

I just changed the oil in my car with synthetic oil. I have always been a stickler about changing the oil every 3,000 miles or three months but things have changed. First I have a new car and I retired. I bought the car in 2009, it was a 2008 model, so the oil was a year or more old when I bought it. I changed it immediately and then again a few months ago when the mileage reached 5,000 miles.

Here is the question, I drive this car very little, less that 2,300 miles in the five months since my last oil change. I live in a temperate climate (Virginia) so there are no seasonal demands on the oil. This last change I deciced to use synthetic oil, I know it is supposed to last longer mileage wise but should I be concerned that the viscosity will break down if I don’t change it for 8, 9 or even 10 months?
