What changes the story is that Castrol Edge TurboDiesel is a longlife oil and its specified oil change interval by some manufacturers is 30 000kms, so doing 33000kms in 18 months isn`t really pushing it.
Also an 03 TDI has electronically-controlled injectors so it burns cleaner and makes fewer deposits in the oil.
But I`m very curious what the oil will be like in a year or two, so please report back to us Artan.

My current understanding is that by having:
- a quality synthetic oil
- an engine which burns clean and doesnt mix fuel with the oil
- a way to let absolutely no dirt in the air intake
- an easy driving style so the engine doesn`t torture the oil

you can go way longer with your oil.
