Changing M1 oil at 3k miles is WAY overkill and is just wasting your money and time for no good reason. At the very least, I would wait until 5k to change out synthetic.

JET, I would stay away from Royal Purple fluids if I were you; their beginning protection is OK (by no means better than Redline, M1, Amsoil, etc.) but their aditive package is not very durable at all and wears out quite quickly. If you can stomach the price, its pretty tough to beat Redline engine oil. Actually, with the exception of 75W-90 gear oil, everything Redline makes is great quality.
