For how long can we wait to change oil in the TL-S?

I used to change oil at 6000 KM interval. But it happens so fast as I drive a lot, like in 2 months, a new oil change has to occur

Can I do a 10 000 KM interval oil change? Is this damaging for the car?

 

I change oil every 3000 miles. Every 5-6 Kilometers for you sounds good though some members will tell you they do it every 7500 miles. It is just a matter of preference and driving style. If you drive your car harder (not more) then you should change your oil more often.
