I have had my 2.2 coupe since January and recently the engine started to tap. It turned out there was hardly any oil as I did not realise the warning light was for pressure not the level.
Anyway when I realised it needed oil I added 2.5 litres of castrol that was approximately 2.5 months ago. Today I had to add 1.5 litres as it ran out again.
Can anyone tell me if I change the oil how much do I need to put in to be near the maximum level?
Would I be right in thinking a change and then monitor the consumption would be better than carry on topping it up?
There are no signs of leaking anywhere.
