Re: Who\'s changing oil at 5000 or 10000
I use delvac in my old mercedes and change it every 10k with no filter changes until 10k. it works out great.

The "book" says every 10,000 miles. Filter every 10,000 miles, too. Any dealership that says otherwise is deliberately trying to rip off its customers.
At 10K the soot content of the oil will be about 1%, give or take. Delvac 1 can easily handle more than three times that much without a problem. If you change your Delvac 1 before 10K miles you're wasting your money.

Umm,
I'm not sure who's book you're looking at, but my Bentley's manual says for a 99 or 00 model TDI, that Engine Oil changes should occur at
5K, 10K, then 20K, 30K, 40K, 50K, 60K, 70K, 80K, 90K, and 100K
This I would think is technically "by the book". That is of course if the operator's manual changed this?

This raises an interesting question. How much soot (% wise) does it take to discolor the oil? How much does it take to turn it black?
Oil left in for 10,000 miles without the Epsilonian device will be black as the ace of spaces long before this.
BTW, just to answer the question...I compromise and try to change the oil and filter every 10,000 km (6,210 miles). At my current levels of driving this is going to be at least 8 months, so I may cut it back to 6 months.

Changing oil and filter every 5k miles.
Using Chevron Delo Synthetic 5w-40.
Was going to go to 10k changes but our Golf lives its life in the city 98% of the time. Gets started - driven about 5 miles - gets shut down.
Repeat process at nite.
I try to get it from the wife every so often and ring it out a bit, but with all of the stop and go driving I'm going to keep the oil changes short.

Epsolonian has nothing to do with the color of the oil.
The soot content has nothing to do with the color of the oil. Oil can be black and have a soot content of 0.0%, or a soot content of 6% and still be the same color. your eyes jsut cant decide how dirty the oil is in this case. only analysis.

Can you send me a copy of that book, I always wanted a copy of "Lying, Cheating, & Stealing Your Way to Increased Dealer Profits"?

I go with the 10K philosophy and have had no engine problems to speak of for nearly 65K happy driving miles.

Re: Who\'s changing oil at 5000 or 10000
I change every 5K for a few reasons. First, it costs all of an extra 30 bucks if you have it changed and that adds up to a whopping total of $300 tops every 100K, even cheaper if you DIY. Second, there are a lot of variables here. If you drive soft, drive highway, and EGR bypass, 10K is probably fine. But I drive pretty hard, have a mix of city/highway, am chipped, use heavy fuel additives, and have an automatic. This equals heat, and I'd rather fork out $300 extra over each 4 year period to save the motor. It's cheap insurance.

Re: Who\'s changing oil at 5000 or 10000
It's not true about the blackness of the oil not depending on soot. I haven't done analysis, but my Passat has noticably blacker oil than the a4s. You can see it on the dipstick if you check the oil back-to-back. Also, I put a drop from the dipstick on a coffee filter, and it was very different -- the pattern and the color. Same oil (Delvac), fewer miles on the oil. Clearly it's soot. (The passats just seem to be sootier).

Delvac 1 and filter every 10K miless since 20K;
46K on the beastie now.
(Have used Mobil 1 in all my gassers since the early '80s at every 5K. The math is sooo easy at 5K)

5, 10, 20, 30, 40, ... is the way to go if you use good oil. Change both oil and filter at the same time. The synthetic oil doesn't shear down and goo up oil filters like dino oil would so there's not much benefit in changing early.
For experimental purposes, I run with a bypass filter and extended drains up to 53,000 miles with oil analysis results to back it up. My engine looks just as clean as anyone else who's used the oil that I have.

Re: Who\'s changing oil at 5000 or 10000
On my mildly-modded earlier car, coupled with my fairly short (4 mile) drive to work, I was seriously loading the oil FAST with soot and destroying the TBN.
I intend to check the injectors soon to see if the atomization is all out of whack, but in the last oil analysis performed, I was already putting 3.4% soot @ 3300 miles. The oil was changed around 5k. Some work has already been done to address the soot problem since the last oil change, and I will likely do my drains between 6-7.5k (the latter is as specified by the owner's manual) using an OEM oil filter and a Group III or better synthetic oil like Petro Canada Duron XL. I'll do this until subsequent oil analyses suggest it's safe to go further, but I doubt it. I'm paying around $12 for a 4L jug compared to $18+. Playing it safe is a no brainer.

Re: Who\'s changing oil at 5000 or 10000
Earlier Passat TDI's and engines running the .205mm injectors put out lots of soot. It is not uncommon to reach the 3% soot limit for passenger car diesels (as per Oil Analyzers) in just 5000 miles of use. If you own one of these vehicles oil analysis @ 5k is highly recommended to determine a conservative oil/filter change interval.
I don't see any great benefit in changing just the filter @ 5k, except for the earlier engines with the spin on filter. In this case you would be adding one quart of fresh oil after the filter change. This would help to dilute any contaminents and replenish the additive levels.

Re: Who\'s changing oil at 5000 or 10000
I too have had too much soot for a 10K mile oil change... 5.3%.. back to 5K for me until I get my soot levels down. My car is a chipped A3 Jetta. I think part of my problem may be a clogging intake, though; even running on 70% biodiesel I had a lot of smoke. I plan to clean the intake and perhaps go back to stock chips for awhile to see if that helps.

Really!? Spoken from experience? I'm surprised the Epsilonians have not jumped all over this one.
It is a favorite test to show soot patterns in the oil on tissue paper from cars with and without Epsilon device. If for some reason your EGR stops functioning, the oil gets blacked at a FAR slower rate. Black oil is dirty oil.

I have 110,000 miles on a stock 98 Jetta TDI. Mostly highway miles. Always use Power Services. Change Castrol 5W40 at dealer three times every 20,000 miles. Car runs and drives like it did new.

On my 13th-month pay: filter and oil change. On my 14th-month pay: filter and oil change, together with the yearly service. A space of six months, irregardless of mileage(which on the average I do 20000 Km mostly city driving). Just following UPsolute´s advice - and no Delvac here!

I don't know what % soot it takes to turn the oil black, but I can tell you it happens within a couple hundred miles on a new engine. So the anwser is VERY LITTLE. You can't tell anything just by looking at diesel oil.
Change the oil and it'll be instantly black just from the residue of the old stuff.

Uhh...Car54...have you ever SEEN oil that is still "clear" with 6% soot? And if you ever buy brand new oil with 0% soot that is inky black, get a refund.
