Hi Guys, I have also noticed the tappet noise recently in my GP1 (80,000km) and observed that the fuel efficiency has dropped considerably. I am using semi synthetic engine oil 10W30 and I can see that it is discoloured after around 3000km run. However, the engine oil level remains healthy. The chasis number lies within the range specified (1200002-1242186) for warranty extension. I am wondering whether I might have the same piston ring issue or some other issue. A little heads up by anyone would be helpful before I visit S*****d Motors.
