Thanks Charles. I use 0w40 Mobil One or its equivalent and service every 7,500km Or about just under 5,000 miles. it's filled up to about 1 notch below full on the dash meter.

Any idea what's the mileage before another cleaning is required?

 

I can't answer how often cleaning is needed. We don't own that equipment and have never done that service in our shop. I would recommend changing oils to DI40 or if your car is under warranty still, use a 5w40 or 5w50 that carries the A40 approval instead of M1 0w40.
