If you consume a little oil and need to add occasionally you will not hurt the engine going 10,000 miles. I change mine close to when the yellow light comes on. No idea how many miles it's based on liters of gas consumed I think (which makes far far more sense) red light comes on at 20% past recommended. I don't recommend letting red light kick on I needed the dealer to reset that when I took too long once. When. I add a quart every 2000 miles or so I've changed half the oil before the full change. Mobil 1 has no real wear after 10,000 miles only gets dirty from combustion else could go 20,000 or more
