Oil change at every service (every ~7500 miles) for my bike so of course there has to be a test ride and a good test ride should include a full throttle acceleration up to top speed. For that the engine should be warmed up what means 10 miles is more or less the minimum to go.
Of course with an oil change only that's not necessary.
