Full disclosure: I'm no expert on oils, this is just some of the information I've gathered from researching on my own. To add to what @Paulster2 and @BrianKnoblauch said, one of the reasons a time and mileage are both specified has to do with the what happens as the oil is used and as it ages. Part of the oil's job is to neutralize the by-products of ...
To add to what @BrianKnoblauch said, there are other reasons why I wouldn't let it run that long. The main reason is the additive package which is delivered in the oil breaks down over time. Once the additives breakdown, the oil will no longer clean like it's supposed to, nor have the viscosity variance we see in multi-weight oils. Once this happens, your ...
It's 15,000km or 1 year, which ever comes first. If you only go 4,000km in 1 year, then you should change the oil at 1 year.
If they are going to take the engine apart, they're probably going to drain the oil. A good shop won't put the same oil back that they drained out unless it's obviously fresh and clean. With that in mind, it's better to wait until they've done their work before you change the oil. Or actually, it's better to give them your jug of oil and ask them to do it ...

I've always had good luck with the kerosene method. Which is adding about a quart of kerosene to the oil and brining the temperature of the engine up to running temp for 5 minutes then drain. Then I use Mobil 1 full synthetic oil and a new decent filter. After 5000 miles I change the filter. Then at 10,000 miles I change the oil and the filter again. My '86 ...
I change the oil every 18,000 miles. My tdi is on longlife service plan and I use only the best long life oil.
If you are having engine work done (where it has to be torn down or taken apart) have the shop do the oil change in conjunction with the maintenance. I suggest this because they may get contaminants into the oil from the work, such as antifreeze or gasket residue. If it is just other maintenance being done, such as suspension work, it really doesn't make a ...
