I've just bought a 1992 Diversion 600, and it does everything I thought it would. However, when i start it the oil light comes on after a short time, stays on for a few minutes, and then disappears. There's no sign that it's using oil. Is this to do with the levels not registering until it's slightly warm, or have I got a problem? Any info from 600 owners would be very welcome,
Thanks
