Default 2000 Golf TDI oil change intervals

Hello
I am a new on this forum and would like to say it is a great source of info. Been reading for weeks now on different topics and it has been great. Oil and lubrication topics seems to be the higest when it comes to different opinions and preferances.
I have been looking into what people use for oils and the change intervals.
I personally in my 2000 TDi golf use Castrol Syntec 5w40 (502,505.00) that I get dirctly from VW dealer for about $8.50 canadian per liter. This is cheaper than Wall Mart up here in canada. I change it every 6000Km(4000mi).
I am the second owner of the car and the first owner was using this oil from the day 1 in this car so I kept with the same oil. I chenge it very offten because with the oil and filtel it costs me about $55 canadian/change.
When I spoke to one of the vw specialized shop mechanics he told me to stick with the 6-7K km per oil change and I should be very safe, When i spoke with second vw mechanic he told me to go with 10K km (6 1/4K mi) oil changes. On these forums I see that most of the people go with 10k miles (16 000km) oil intervals.
To summerize:
I have found that people change their oil anywhere from 3000 to 25000mile intervals. I will keep on doing my oil changes at 6k km because it is not expensive and my TDI keeps on runing mint. IT is probably overkill but keeps me happy.
I also use 8oz of PS aditive per tank in winter and about 6oz in summer to keep the injectors clean and lubed as well to give it some cetane boost.
Do not see much difference with the additve.

Anybody else on here that has low oil change interval and which oil do you use?

Cheers

By shortening the OCI you are INCREASING wear on your engine and wasting money.

10k miles or 16k km.

I stick to what VW recommends for both interval and oil. If you follow this you likely will never wear out the engine. Shorting the interval is OK but really there is little to gain. Very few VW engines die due to engine wear unless the owner fails to follow the recommendations.

Note: If you have modified the engine or have some very unusual situation, this may not apply.

Does anyone have some real world facts which compare OEM recommended oil changes vs. mofre frequent oil changes on stock engines?

It has to be beyond useless to change the oil more often than 10k.

While it is always subjective, I think there have been many UOA results showing that slightly used motor oil returns better results than brand new motor oil. This is probably due to the fact that the lubricants are designed to last XXXX number of miles/months/hours, and that they want the stuff to work best in a 'used' state as it will essentially BE used in very short order after a changeout.

The massive PILES of UOA data showing good oil results on 10,000 mile/16,000 km is such that I have no idea why anyone would doubt that interval's validity.

Joe, the guys are correct. The wear curve plots out to look like a sinusoidal curve. Wear goes up, wear decrease with accumulation of miles, wear increases again as oil starts to wear out.

Let me ask this: If a person buys a new VW diesel and does the oil changes at 1/2 distance/time recommended by manufacturer, will the VW void the warranty?

LOL....half the dealers already do that, so my answer is no. But rest assured, they will find some other way.

It may be hard to accept, but there are sooo many guys out there with high mileage engines going 10K (and some longer, even much longer) that no reson to doubt it.

How many of you have seen a stock VW TDI with a worn out engine, that has had recommended service and oil changes, that could have lived longer if it had more oil changes?

I currently own (2) 2002 Golfs. One with 120k and the other with lower mileage at 60k. I also owned a 98 Beetle TDI that I sold with 50k on it. My mother has a 2001 Beetle with 70k. The oil changes were always done at 10k on all of these cars. I will say that none of them have oil consumption issues. My personal car, the one with 120k, starts and runs like the day I bought it. 120k is considered low mileage for a TDI, but for other gas cars this may not be so. If I was able to do 10k changes up to this point with no ill effect, I would say that no damage is being done whatsoever. I would be more concerned doing more frequent changes and have the engine run dry for those first 30 seconds or so, than by using a high quality synthetic and leaving it in the sump for 10k.
BTW: My valve cover was off at 80k and the lobes on the cam looked like brand new.
