If you really want to be on the safe side a good local lab should be able to perform a test on a 30ml sample of oil for about £20. The result will tell you how contaminated and with what the oil is. Which will tell you when you need to change it.
Then again seven litres of oil and a filter every 10k is able to be done from £25 upwards depending on the oil you use.

I often send lube oil samples to Caterpillar in Desford for analysis from oil changes performed on large generator sets.
They are able to tell from that, exactly what components will be required on the next pull down of the engine at a 3000 hour service......brilliant really
On my own cars, regardless of the manufacturers set oil change intervals, it's every 8000 miles, or six months for a lube oil and filter change, and twelve months irrespective of mileage for a fuel and air filter change.
A wise man one told me this "you look after the oil, and the bearings will look after themselves", this advice has stood me in good stead over the million and a half miles so I've driven so far
