Re: how often do u change ur engine oil?
Unless its the first oil change for new car. where got need 5k km oil change interval.. Anyway I know a lot of hiadee do that. Its nothing wrong, but point is - is there a need to be so frequent. A good quality oil can last, dont use those 'boutique brands' as they do not last.
On my 320i, I change at 10,000km intervals. On the 335 which runs hotter, I change it every 8,000km. Good enough.
