MAny parts of a car require servicing to ensure a long life. For example brakes bind and headgaskets go on poorly maintained cars.
The oil will suffer breakdown, irrespective of mileage, due to acid and water content build-up. In fact a low mileage engine will suffer more condensation and fuel dilution than a higher mileage one due to not getting to a high enough temperature to boil off the dilutants.
Even with a fully synthethic oil I would never leave the oil longer than two years, and in reality one or so.
Engines that use centrifugal and bypass filters will allow the oil to run for longer, typically 50,000 miles, but this only really applies to engines run for extended periods and given frequent analisys.
A friend of mine uses the theory of continually topping the oil instead of changing it and his cars are knac***d way before time.
An old adage is that maintenance costs save ten times their value against repair cost. i.e. saving £100 on maintenance will cost £1000 in repairs, this can be borne out by costs to get cars through the MOT test, often well exceeding what the annual maintenance cost would have been.
