Hi All,

I was doing some web surfing the other day and came accross a performance company in AUS that performed an engine detox with liqui moly is this a standard thing for the 63 motor???

Just another way to have owners part with their money unnecessarily. A 40,000KM engine properly maintained doesn't need, and won't benefit from an oil flush.

Even if these types of products might work it's way too early to consider it. Personally I'm dubious as to how much "baked-on" deposits can be removed in the 10-25 minutes the product circulates in your engine. Also, there is always a concern with compatibility of internal seals with the different solvents used. Take a pass on it...IMHO.

this isnt a colon cleanse

Doesn't sound right. Just follow the factory service schedule and you should be fine unless you race your car or push it hard constantly, then change the fluids out earlier.

Agreed!

They do it to alot of their cars, its not because its an AMG.

Having said that though, these 63 motors love a flush out,

If you've ever pulled apart an engine that's been properly maintained, you know that you don't get anything accumulating unless something has gone terribly wrong.
Many years ago, I took apart the 350 in a TransAm I owned at ~90,000Km for a performance rebuild and the internals sparkled. The only things that didn't look brand new were the tops of the pistons - simply due to normal combustion.

This is incorrect. Do some research on the B7 RS4's. Carbon buildup was a *****. There was even buildup in the early stages of the engine.... I have seen some pictures of 63 engines with some gunk as well. Don't rule this engine out. Although it may be VERY well built, it still has its problems.

I am more inclined to your way of thinking. These oil/solvents would be so weak in the acidity as to not disupt any filters or rubbers. I am sure on diesel vehicles it would be required but with our engines at this amount of KM's would be like pissing in the wind.

Does this engine have direct injection (DI)?
DI engines are definitely prone to getting build-up on the intake valves. There are pics of build up on the BMW N54 and Porsche DI engines.
The "treatment" is usually a crushed walnut cleaning.
