Oil consumption A6 3.0l DDVB

The A6 has currently traveled less than 20,000 km. Within approximately 8,000 km, the oil level has decreased by about 80%. According to the car dealership, an oil consumption of 0.5 liters per 1,000 km is within the manufacturer's tolerance.

The car dealership has only performed a visual inspection for leaks, which were negative. The car is still under warranty. I find the oil consumption to be too high.

Are there any specific issues with this engine?

Zitat:

Oil level has decreased by approximately 80%.

Do you mean the level between the minimum and maximum of the gauge? The difference will not be more than 1.5 liters even with the V6 engine. Therefore, the consumption is approximately 1 liter per 8000 km.

For me, within a completely normal range, there's a chance that I was used to dealing with oil consumption of up to 1 liter/1000km about 40 years ago, with a limit according to VAG being 1.5 liters/1000km at that time.

BMW (especially those of the 02 series) was called "BMÖl" due to the usual blue smoke.

I taught my daughter to immediately report if the oil started to increase.

That's right. Audi says that the difference between the minimum and maximum should be 1 liter. We'll see, because my brother-in-law now has to document the fuel consumption.

I know that the consumption isn't dramatic. However, I think it's too much for a new and modern car. His old A6 3.0 TDI with 330,000 km consumed less oil.

Can anyone tell me which Shell Helix Ultra oil is used in my Audi? It should be ensured that the same oil is used for refilling.

Unfortunately, the car dealership is unable to do this :twisted:

The answer is simply:

You can use the following oils for your vehicle:

Shell Helix Ultra ECT C2 C3 SAE 0W-30 50400/50700
Shell Helix Ultra Professional AV-L SAE 0W-30 50400/50700

Hello Andreas,

the hybrid horse from your brother-in-law needs engine oil with the manufacturer's approval VW 507 00.

According to the manufacturer, a long-life engine oil of the 3rd generation should be used. SAE 0W-30.

Filling volume with filter: 6.10 L

The oil can be found in the parts catalog under the part number

G S55 545 D2

.

Otherwise, the model occasionally has problems with the realistic oil level display.

A "low oil level" warning can occur even when the actual oil level is still approximately 25% above the minimum.

If oil is now refilled, it can lead to overfilling...

If there is a significant oil overflow, this can cause a misreading of the oil level sensor, which in turn triggers an unjustified "low oil level" warning.

What does this mean for your brother-in-law?

If he wants to seriously document his oil consumption, he will need an oil measuring stick again. (This costs approximately €20.00)

The readings in the VCDS fluctuate daily and do not provide 100% accurate information.

If it is not a leased vehicle, I can recommend a ceramic additive based on my experience.

Does this help you?

Best regards,
Michael

What do you think of "...leaving the church in the village intact..."? The car dealership can't possibly know exactly what Audi entered for the manufacturing date.

Either stick to the specifications specified in the operating manual when refilling (that's how I do it), or drain all the old oil and refill with new oil, plus buy a spare, so that the exact same oil is used for refilling. Ideally, also do an engine flush:ntrs:.

The DDVB is nothing special.
What is a hybrid traction unit?

Thank you for the information.

The Audi is not a leased vehicle, but it still has warranty. Therefore, I assume we should avoid ceramic coatings. Just out of curiosity: which one would you recommend?

How complicated is it to install this measuring tape?

And you're right, Herbert :)

That wasn't entirely serious on my part either. The drawbar is called Audi A6 50 TDI Hybrid Quattro... It sounds like endless power... and in reality, the engine has significantly less power than the old biturbo. -Never mind-

Back to the topic:

The tube for the dipstick to drain the engine oil is already in the engine. It is equipped with a closing cap.

There is no dipstick for permanent use anymore.
This item is called KD dipstick T40178 and is only used for temporary checks.

Since this is not a leased vehicle, I would follow Herbert's advice. Perform a proper oil change with engine flush. Then, fill the exact amount and observe.

Personally, I use Liqui Moly products without being able to say whether they are better or worse than others.

I find the technical hotline and advice to be good.

Best regards,

Michael

Current status after approximately 32,000 km: My brother-in-law has added 0.8 liters of oil twice within the past 21,000 km, according to the car's computer display, without using the dipstick.

Perhaps this is the new contribution to environmental protection with a modern engine:lol:

As a note, he should aim for an oil change for all vehicles with a maximum mileage of 15,000 km if he wants to keep his engine in good condition.

That's always a good idea. However, it will only mitigate the wear and tear, because I still maintain that there's something wrong with the engine.

Has anything significant been changed in this engine compared to its predecessors? Not that it will suffer a major engine failure like AMG did with some engines between 80,000 and 150,000 miles due to the high-strength aluminum coating on the cylinder walls:lol

It is perfectly normal for a motor to burn some oil within a certain range, as a 100% seal is not possible. However, a mechanic might be able to explain this to you better...

The fact is that there is always a presence of fuel, water, and soot in the engine oil, which destroys the additives and promotes wear. Therefore, every owner who uses long-life oil will contribute to internal engine wear.

As a good example, I have the AFN in my neighbor's A4, which I'm currently maintaining, with approximately 675,000 km on the odometer. He gets an oil change every 15,000 km, and I've observed that he uses almost no engine oil (around 10-12,000 km) between oil changes. However, on the last few thousand km, I have to add about half a liter after each oil change, and then it's back to 0.

I am 100% with you. Your statement is valid since the invention of internal combustion engines. However, it cannot be that his old ASB (3l V6 TDI) with over 330,000 km consumed significantly less oil over 30,000 km than the new engine.

Therefore, I am particularly interested in whether "something has been changed or worsened in the design/coating of the engine." The many plastic parts and cost-saving measures in handling that are primarily seen also do not bode well.

You can have two identical cars with identical engines, one needing 0.00 liters of oil and the other needing 0.2 liters per 1000 km, and how do you explain that? It's due to manufacturing tolerances.

The ASB also has a completely different type of fuel injection and, above all, a different type of exhaust cleaning system compared to the current engine.

The engine oil is subjected to much more stress and therefore becomes more contaminated, which also leads to increased wear and tear if the engine oil loses its original lubricating effect.

An oil analysis of both engines under corresponding operating conditions could be informative.
