Ok. I can see your reasoning for a low annual mileage vehicle. I change the oil and filter on my play cars every 12 months because they don't get miles put on them. I use Mobil 1. On my daily driver, a Cummins, I use regular Rotella T4 and change it every 5-7k. Did this on my previous '03 Cummins that made 502hp and 1060 ft/lb to the wheels for almost 300k miles and the engine was clean as new inside and used no oil. I'm still over maintaining them according to Cummins but that's what works for me.
