Which oil, meeting the 505 01 specification, are you considering?

LM Diesel HighTech - but not in the product itself, but already in the canister.
The Gratis Dose 506.01 is from Mobil.

That means you only refilled 0.25 liters after ~14,000 kilometers

Yes, the oil level is now lower than it was when the car had 0 kilometers on it. I probably won't reach the minimum price before the exchange.
The actual consumption is likely to be around 0.5 - 0.75 liters higher now.

Until the change, I probably won't reach the minimum .


At what mileage should it be replaced?

According to the remaining service interval display (read with VAGCOM), it's 87 days, if I recall correctly. By then, it will have driven approximately 16,000 kilometers.

The remaining kilometers would probably last longer for my daily commute (since there were still quite a few free kilometers available).
I don't really understand the calculation, but ultimately, it doesn't matter to me.

@Julian:

You wrote that you would perform long-life servicing as long as there was a warranty on the car. That's basically okay, but what's the point of giving an old engine, which has already been pushed to its limits with long-life servicing, better maintenance when it's already suffered so much? The long-life servicing was only done so that customers could brag to their friends that they only need to go to the dealership every 35,000 or even 50,000 kilometers, and that the car is done for at 150,000 kilometers. Then, the calculations of the VAG engineers proved to be correct, much to the customer's dismay.

I personally experienced this with my car, at 130,000 km, where all four camshafts had worn down (more than 0.5mm), and the workshop thanked me for the €2,886 that the repair cost. For that, you can change the oil every 15,000 km for your entire life, using the best oil available.
If I ever become financially able to buy a new car again, regardless of the brand, you can be sure that the oil will be changed no later than 1 year or 20,000 km, regardless of the long-life oil interval.

Opinions on oil change intervals vary widely.
We all know that engines need oil for lubrication and cooling. According to oil manufacturers, today's oils are all capable of reliably providing lubrication and cooling for well over 50,000 kilometers. This is likely one of the reasons why automobile manufacturers have confidently introduced long-life oil change intervals for their models. However, it's not the degradation of the oil that drives us to change it, but rather the limited capacity of the filter elements. Once the filter is clogged and dirty, it can potentially lead to increased wear on engine components due to unclean oil.
The oils, in any case, are still capable of providing 100% lubrication and cooling even after a complete extended drain interval.
I'm certainly not a proponent of extended oil change intervals. Therefore, I would suggest that if you want to use extended oil change intervals, you should change the oil filter halfway through the interval. The cost is under 20 euros, and it certainly can't hurt, right?

...we have discovered that an LL² oil has a certain shear stability limit, which can lead to increased wear in the engine. This issue has now been resolved with the introduction of LL³ oils, which I have recently started using myself.

I'm still waiting for the wearcheck analysis from my second oil change interval, but the initial test already showed that LL2 oils have an extremely high capacity to carry contaminants and, even after 32,000 km, exhibit an overall better quality compared to, for example, a 5W-40 oil approximately 3,000 km after the last change.
The only contaminant found in the oil is silicon (dust, etc.), which I have tried to reduce by changing the engine air filter more frequently (every 15,000 km instead of 90,000 km) during the second service interval. Let's see if it made any difference.

Okay, what kind of AFB are you using? The noise levels (NW) on the 2.5 are nothing special, almost like a feature or a bug, depending on how you look at it. As far as I can tell, my noise levels still look fine. But is it a 1.9 PD?
My A4, which I use for comparison here in Wü, has already accumulated 240,000 km as a taxi, the tires need to be changed approximately every 20-25,000 km, and the driver is satisfied.

I'm certainly not a proponent of extended oil change intervals. Therefore, I would suggest that if you want to use extended oil change intervals, you should change the oil filter halfway through the interval. The costs are less than 20 euros, and it certainly can't hurt, right?

Will changing the filter actually make a difference? Do you have any in-depth knowledge on this (e.g., oil analysis), or are you just doing it based on intuition?
