For those who asked, normal operating temperature is at least three bars on the gauge, since this is where the thermostat opens. Warming it in the driveway to this level may be insufficient, since the oil warms more slowly than the coolant. I highly recommend checking the level after a ride. If you can't, let the engine stay at three bars or above for several minutes before you check. Even then, your oil level may read low, and if you add, you could overfill.
