Thank you one and all for you comments and advice. I am going to change the plugs, and I'll do the over run test, and see if I get any smoke. I still can't fathom where the oil is going with nothing bloody obvious. Check the oil last night. This is after servicing at the weekend (engine flush new oil and filter. Run around the block, check oil level, all good) On the dipstick, after 89 miles its halfway between the full/add oil marks. I can truly say that I am doing my bit in "Ridding the World of Hydrocarbons"

Yes, three were, as I would describe "Finger Tight". But I fail to see why this would have an effect on oil consumption. And I agree It is Hoovering the oil, hence my initial question, "where is all the oil going" I do not see smoke, and my driveway is drip free.

I did have the plugs out, and they looked fine. The gap was a bit shy of 35 thou. Did not see any signs of the electrode burnt away, so back in they went! Running fine, nice idle, no missing, and good acceleration(for a 1.8 Skoda superb - it ain't no Ferrari). As I've said, at great personal expense I have purchased some new ones, I will fit these at the W/E. I'll give the old ones a photo shoot and post the pics.

Ok. So, if the gap has increased by being eroded, why not just close up the plug gap, and if the Gap has not increased, is there any other reason to change the plugs, other than the plug mnfs (and Garage, if they change them), extracting £60 plus labour of you?

Sorry I did not take any pictures of the Spark Plugs, As I have purchased a set (makes me week) I will post a picture for completeness. Although all of them were fine not sooted up, or burnt away. Can anyone explain to me why one would need to change a spark plug. I appreciate if they are carbonized up, or burnt away, one might want to change them, but this would be a bit of a folly, as there would be underlying causes of carbon, or burning that should be addressed.

I am not a lover of changing Spark plugs willy nilly, especially as they are now £14 each. I had my last car do 118000 miles (when I sold it) on the original set, and it never missed a beat. I must confess that although I put back the originals after cleaning them, I have bought a new set. I haven't decided whether to put them in yet, I will wait until the PCV valve arrives. It runs too well at the moment - if it ain't broke don't fix it!

Will do. Yes I posted the question in the wrong location, and don't know how to delete it, it seems to have a life of its own.

I took out the plugs and nothing was untoward, other than three were loose. Gave the plugs a scrape and popped them back in. I also took of the PCV / oil separator thingy, nothing obvious there, the springy valve thing looked OK, and sprang back wheb I poked it. There was evidenve of oil comming out of teh front pipe, into the inlet manifold. I have ordered a new PCV/oil separator-£30 worth a punt.

Well I took out the plugs - caked with oil they were not. Three were loose though. I also tool off the PCV/oil separator plastic thing on top of the engine. I could not see anything obvious, I poked the valve bit and all seemed well, but there was evidence of oil coming through the front pipe to the inlet manifold. I have ordered a new one - £30 worth a punt. I am certainly not going to be spending £2500 on new pistons etc. That Buys you an awful lot of oil.

Thanks for that. I'll take the plugs out and have a look, I would assume that if the rings have gone then there would be oil (black as your hat) deposits on the plugs. The reason that I haven't dived into the engine, is that there is no plumes of smoke, regardless of how hard I drive it. I'll do a compression test at the same time and re post.

Greetings one and all. Firstly I am new to this forum, but have been a happy Skoda owner for the last 5/6 years. My car -Superb 2011 1.8 TSI has been and still is, more than reliable, when I purchased it new from the dealership. I do all of my own maintenance, and use the correct parts and Fluids.. I have noticed that the oil consumption in my car has gone from zero to what I would call excessive - 1 Lt every 300 miles. Now, I have build engines and run classics for more years than I can mention, and High oil consumption is always combined with something else. Plumes of Smoke, Oil patches when parked, lack of performance. I get NONE of this. It starts runs, and goes like a train (without the steam and smoke). It is getting through nearly a teaspoon a mile, where is all the oil going? The car has only done 70,000 miles. When I had a blown Turbo on a previous car it used less oil than that, and you could not see me after I passed you. Any suggestions? PCV valve ? I cant believe its rings. Where is the oil going?
