I personally use Shell Ultra 5W/40 fully syn and run it for 2 years. This is mainly because the car usage now is low and I struggle to do 10000km in 2 years. I do try to do a longish run every so often to evaporate any condensation and fuel from the oil. When usage was high and I was towing a caravan in our hot conditions, I was changing yearly, regardless of mileage.
