How to Use Wurth Engine Flush and Change Oil on 2.0 TFSi

If your Skoda dealer is promoting it then that negates the warranty comments I read via Google, which of course are just that - 'Experts' on the internet.

You have clearly been very thorough indeed and so it's very doubtful you have done any damage. My understanding is that it's important to leave as little flush residue as possible [cue for Hedge!].

Personally I'm neither for or against engine flushing - I'm interested and keen to learn both pros and cons.

I was worried about the flush remaining but as it was mixed in with the old oil which i drained i thought it would be ok. But just to be on the safe side i left the Sump plug off and poured about 1/2 litre of fresh clean oil into the filler cap and let that drain right through before applying sump plug etc

So hopefully it will have got rid of it all.

Will see if my Valves and Pistons all melt

I do seem to remember a TSB citing that the use of such flushes was not approved by Skoda.  I'll have a look if I remember when I get home.

Hmm that would be interesting as Caffyns Skoda in Ashford are advertising it

The problem is Carl that the dealers are merely franchises and often they do 'go it alone', for instance they aren't restricted on oil etc.

Gotcha.

But surely then if there were any problems arising from it the dealer would be liable for any repairs.

I did ask them when they recommended it be used and they said pretty similar to what i was thinking. Or to be precise once every 50k miles.

Hope i aint foooked the engine then

....I reckon that if this stuff seriously fooked the engine it would already have been withdrawn from the market plus lots of lawsuits flying around.

Probably just a case of needing to use very carefully etc - Which appears to be what you have done.

Just because VAG don't endorse the product doesn't necessarily mean it will harm your engine.

I use it and always have, it works really well. We are a Forte dealer, and sell it to our customers, the results are outstanding and never had a problem.

Never heard the warranty issue problems either, I know loads of dealers the use it.

Good guide I'll be using this today!

The definative answer on engine flush will appear on both erWin, and also ETKA.  erWin will detail the specific procedure, and ETKA will list the specific parts.

As others have said, most stealers are franchises, and don't give a toss about the long-term reliablity of the cars they sell and service.  Just look how many official franchised dealers use Quantum oils - they are only meant to use genuine premium brand oils - Quantum are for only independent workshops.

Onto specifics of engine flushing agents.  Providing that the engine oil has been changed per recommended intervals (and the correct spec quality oil is used and the filter changed) - then there is absolute no need for engine flushes.

Flushing oils and flushing additives were designed for old skool dino mineral oils, or when oil change interval had exceeded the recommended interval by some margin (usually more than 50% over) and became heavily sludged, or when incorrect oil was used.  Another specialist requirement was in two-stroke engines when changing from mineral based oils to vegetable oils . . . . ahhhhhh, those headdy daze of the smell of Castor R racing oils . . . .

So, in summary - DON'T use flushing oils or additives.
