Modern synthetics are fine on the shelf for years, usage and dilution is what wears modern oils out, not time, modern engines are fairly airtight I'd expect next to no oil degradation, there are many oil analysis for this car that show 10k miles is perfectly fine and time is practically irrelevant.
