Yes, I did use Mobil Delvac within 10k km change oil intervals on our Starex D4BB engine.

No, I didn't change any filters within the 10k km. Guess I forgot to buy an extra liter if I need to refill it just incase.

Since we got it brand new, after the 1000km PMS. I have used it eversince. So far so good, but the mechanic told me that the engine oil could still go further with 2k more kms.

10k was the interval of changing filters same with the oils. But people have told me that sometimes it is not safe to reach the Delvac upto 10k. So I have adjusted it to 8k for oil changes.
