I just took delivery of my third TDI, a 2009 Jetta sportwagen. A friend with extensive VW & diesel experience says I should change the oil at the first 1000 miles, which the car is just under. I called the dealer to make an appointment and they said not to. Any opinions or factual knowledege would be appreciated.

The dealer is usually wrong on most stuff. They spread bad info not out of only ignorance but also laziness. Friends at least mean well but info changes and they may be saying old info.

In any case, I suggest listening to your owner's manual. This is the only official maintenance schedule that is available to the customer. You don't need a 1000 mile oil change. The manual says 10,000 miles for the first change. Diesel engine oil is designed to hold soot and the additives need time to be released.

Most importantly, make sure they use VW 507 spec oil. This is the only engine oil certified to be used in your engine. It doesn't matter if other oils could work, if you have a warranty problem you have to show that it's not caused by improper oil. Some dealers don't want to stock it because it costs extra or because they're lazy. Some tech will just reach for the closest bottle because it's there. Who cares if they take offense, it's your car.

+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.

many more tips, quirks, etc., can be found in the buyer's guide here: http://www.myturbodiesel.com/1000q_how_to/a5/jettachecklist.htm

Thanks, but I'm still a bit confused....

I truly appreciate your replies....I might not have been clear about the fact that this is a brand new car...and just turned 1015 miles today.

So, when ChittyChitty says, "Changing oil would be a good idea if your car had a brand new engine," then I SHOULD call the Dealer and insist on an oil change now or wait till 5,000 miles or wait till the "recommended" 10,000 mile change?

Waiting till 10,000 seems irresponsible to me...but then who has done any independent research on this?

On the other hand, Vent5 says, "the additives need time to be released," and that makes sense to me--so I should wait?

I don't have any problem being a "difficult customer," and being powerful with the dealer, but it would be helpful to get clear advice because my friend, who is extremely knowledgeable about VWs and diesels, may not be talking to me for a while if I don't do this oil change now. He already ran a guilt trip on me about caring for my dogs, but not caring for my car before he hung up on me! But don't worry, we've been pals for 20 years and our friends say we argue like we're married....

I think he means, if your car had a brand new engine as in a rebuild. Your car was run in at the factory and already had an oil change and new filter there. IMHO, wait until 10,000 miles. You can change now but it's not special break in oil. The filter catches most of the stuff floating in there. You won't damage anything by changing early but you won't help anything either. The tiniest particles from engine break in will be in the engine oil but if they're small enough to pass through the filter then they're small enough to not cause any sort of damage. Diesel engine oil has to hold all sorts of crap in there.

What's important is that you use synthetic 507.00 engine oil and make sure that the dealer does too. Warm up the engine with mild driving before you get on it and the engine will last a long time.

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.

http://www.myturbodiesel.com/1000q/enginebreakin.htm

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.

Thanks!!

Thank you to everyone who's replied. Everything you all said was helpful and it's nice that I can save some money, too. Even though this is my third TDI, I know where to come for questions from here on out! Christine
