As I'm very unlikely to be buying anything even close to having a new engine in the near future it's all just "background information" for me.

Just one thing to remember about bike running in being OK at 500 miles. Bike engines run at almost twice the speed of car engines for the same road speed. My own Honda CB 1,000 runs at almost exactly double the engine speed of my R75 at all speeds in top gear.

My point here being that the slower revs of the car engine means a 1,000 miles might be nearer running in distance for a car engine.
