Oil Use !

[brad]

I don't know about the 90TSI but my 147TSI burns 1+ litre per 3,000km and seems to be a perfectly happy/healthy engine

Martin, he has a 118tsi same as mine.

I'm not saying that oil burning is OK - mine uses maybe 400ml in 15,000km so some of them are as tight as a fishes bum.

That's the point about VW/TSI oil consumption that I don't like - the variable nature of VW/TSI oil consumption which creates quality control concerns

Years ago Fiat/Lancia defended oil consumption (which was a fraction of my VW/TSI oil consumption) saying that the final compression barrier is hydraulic, hence some oil consumption can be acceptable

Back then I did a number of Fiat engine rebuilds which were all successful
I helped a friend rebuild a Honda engine and that was a bit of failure
The Honda engine used very low ring to bore pressure compare to Fiat/Lancia/Alfa
The engine worked but it's power, smoothness and oil consumption were not good for a rebuilt engine
