+1 the above.

Listen to the dealer but verify everything they say. Dealers must follow the owner's manual or their technical service bulletins or their manuals. The problem is that they often don't.

Changing oil would be a good idea if your car had a brand new engine. Your engine was run in at the factory and had the oil drained there. The oil filter will catch almost all of the remainder. Diesel oil can last over 10,000 miles and it has lots of soot in it that isn't caught by the filter either. 10,000 miles is reasonable for VW 507 engine oil.

Some types of 507 oil are : Castrol SLX Professional LL03 (VW# gvw 052 195 m2), Motul VW 507.00, and Total Quartz Ineo 5w30 507.00.

Yes, what I meant was that although the car is new, the engine is new, it's not BRAND new. A rebuilt engine should have the oil changed right away.

Read this and drive more, worry less. When was the last time you or anyone you know, had a car that had to have the engine replaced due to NORMAL wear? I know of some cars that had a design defect and would get worn out, or of some random failure. But engines that get proper maintenance and the proper engine oil can last a very long time. Therefore, just use the service intervals suggested in the owner's handbook.

Tons of people have done engine oil analysis and whatnot and found that synthetic diesel engine oil can last even past 10,000 miles without a hitch in the TDI. The problem is that without the expense of oil sampling, you don't know how long so it's just cheaper to change the oil every 10,000 miles. If you want to check for yourself click here http://www.blackstone-labs.com/diesel_engines.html and send a sample to them. Semi truck's diesel engines can hold engine oil for many tens of thousands of miles before a change and have meters on the air filter and a bunch of other stuff because their duty cycles make it more economical to test stuff like oil and filters before changing them. With a car, it's cheaper to just change the oil. And that's why the owner's manual says 10,000 mile engine oil and filter changes.

Here is a forum post where they talk specifically about what's in the castrol 507 oil: http://bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=1382391

Here is a direct link to castrol's specs:

PS, gasoline engines are also switching to 5-10,000 mile changes when quality synthetic engine oil is used. The correct change interval depends on duty cycle, use, climate, etc. but they are holding up just fine. Jiffy lube still says 3,000 miles so that they get more business.
