Luxury Nav Auto purchased July 19th now completed 7700km's. Never had a pinging issue & am averaging 8.9litres per 100km as per computer. Only noise issue has been a rattle from the drink holder lid & the sunvisor swinging around & hitting me in the head when going around a corner & I have it over the drivers side window.

Have always used VPower & use Mobil 1 10w-30 fully synthetic from 1200km's. Other than that no issue's at all. Great car.
