Engine oil flush? Your experience!

I'm planning to have an engine flush done during the upcoming oil change for both of our cars (with 216,000 km and 149,000 km on the odometer, respectively).

Have you had any experience with this? Is something like this also offered directly by AUDI?

I currently favor this product: MOTORCLEAN.

Unfortunately, I couldn't find any better information for you quickly!

Thank you.

Manuel.

hi,
I haven't done anything like that before, but I'll share my opinion:
I think it's really not necessary because, if you look around, the old engines from 20 years ago are still running. It's very, very rare to experience a seized piston. I haven't experienced excessive wear in the form of low compression in my own cars (with 270,000 km, 240,000 km, and 360,000 km on the odometer).
I think the additives in high-quality motor oils are sufficient.
I could even imagine that Motorclean products might not be compatible with the engine oil or other engine components and could cause damage.
My brother once put some kind of fuel additive (likely a fuel system cleaner) in his Polo's gasoline tank.
Actually, the engine didn't sound bad before, but after that, something started rattling, and it wouldn't stop.
It seems to have helped, but whether that's the solution remains to be seen.
greetings

Hello,

IMO, it's definitely good for whoever is selling it!

'Those who have too much money should do what they want, but the oils and...'
The filter systems are so good that something like that is not necessary. I have.
25 years ago, engines with varying mileage were disassembled.
They were always verschandeln on the inside.

Such discussions, or those related to 'oil additives,' belong...
actually falls into the realm of modern myths, such as the spider.
in the yucca palm. I would rather spend the money on a really good meal!

Hello,

Whether it's worthwhile depends on how dirty the engine is inside. The best thing to do is remove the valve cover and see if you can still see the bare metal of the cylinder head, or if there's a millimeter-thick layer of oil sludge on it. In the 1980s, oil sludge was a major issue, and many engines failed due to it. My Golf I GTi 1.8 was also completely sludged up at 54,000 km. I used Liqui Moly's oil sludge remover several times back then, and it made a noticeable difference. After that, I only used fully synthetic oil (previously I had used mineral-based Castrol GTX II/III), and I no longer had any problems with it.

However, modern engines should no longer have this problem, and the oils available have also improved significantly. To my knowledge, diesel engines never really had a problem with oil sludge.

This is not an oil additive that allows you to save 5 liters per 100 km and still enables you to continue driving for up to 1000 km without oil!

This is a product that is added to hot engine oil before an oil change. Then, let the engine idle for another 15 minutes.

During these 15 minutes, this cleaner removes deposits and carbon buildup in the oil system, especially on piston rings, etc.

Since I recently replaced the valve cover gasket on a Polo with only 150,000 km, I can tell you from firsthand experience that a lot of sludge accumulates there!

The Polo has only ever received Mobil 10W-40 oil since it was first registered, and it has been changed every 15,000 km according to the maintenance schedule!

And this cleaning agent is supposed to dissolve the grease, and then it will be drained out along with the old oil!

My question is, has anyone ever performed such a cleaning process before, and with what results?

After the hot, dirty oil has been drained, and the filter has been replaced as usual, there is nothing of it left in the oil circulation system!

The times are gone when you could go out to eat and have a good meal for 15€!

My friend has a 100 V8 S4 Audi with almost 300 horsepower, and he experienced a...
Mileage: 240,000 km (first engine). Also had an engine flush performed.

This add-on worked VERY well. All carbon deposits in the engine were safely removed.
removed.

The only downside: Since this oil change, the car has been using almost 2 liters of oil per 1000 km.
Nothing before!

Great sausage! Greetings and keep your hands off! H-P

Hello everyone!

At AVL List in Graz (a developer of engines for various...), Vehicle manufacturers conducted tests using various engines to evaluate the effects of different oil change intervals, changes in oil quality, and the use of additives.

The result was disappointing.

Engines that operated for an excessively long time with the same oil showed significantly less wear than engines that underwent regular oil changes.

Engines that were switched from mineral oils to synthetic oils showed, the older the engine was, the more likely it was to suffer engine damage. Why? Synthetic oils have a significantly better cleaning power and dissolved old contaminants, which then suddenly clogged the thin oil channels. The same can happen with various cleaning products.

The cleaning power of modern oils is sufficient to prevent contamination in the engine, so what's the point of using cleaning additives?

I'm rather skeptical about these additives and various other supplements, so I wouldn't do it. I only once flushed my old 1.6 diesel engine with the same type of oil, but I changed the oil again after 20 minutes of driving. Whether that was a good idea, I'm not necessarily going to claim, well, what does it matter?

Hi Peter, greetings.

That's exactly the problem...

The engine rattles incessantly afterwards and leaks oil like a sieve.

Let it be...

You can get rid of oil sludge either by using high-quality oil or by driving long distances.

Interestingly, the older Opel models didn't have problems with oil sludge, while the contemporary VW engines were quite prone to it.
in both, the same oil is inside... that's quite strange .

CU Gremlin.

Many engines suffer from the problem of uneven oil circulation, as well as significant temperature variations between different areas. That's a big oven for those collections.

For diesel engines, it's also important that a good oil keeps all the soot particles suspended. Over time, it loses this ability. A lack of oil can also exacerbate this.

I wonder how effective the flushing process is, considering that the dirt that has accumulated over thousands of kilometers is suddenly being flushed through the engine.

I would prefer to use better oil (if possible) and drive a bit more long distances. Consider performing oil changes more frequently.

Hello Manuel,

I have two cars and a Kawasaki, so that's quite a collection!

Oh, I forgot: my lawnmower also has a four-stroke engine.

Okay, putting the jokes aside - if you think you have to do it, then do it!
You wanted to hear opinions. For my part, I am almost 50 years old now.
I've been driving and working on cars since my 18th birthday. And these.
Discussions tend to pop up with a certain regularity - I...
Just skip the unnecessary stuff and give me...
Then it's better to spend the money on the enjoyable things in life.
But maybe we're already entering the realm of philosophy of life!
