Hi John, Yes, I agree. Treating it too gently doesn't do it any good. I'll take it out for a few runs in the next 1000 miles, and if its no good I'll try the millers oils glaze bust. It's only £20. Worth a try.

The rebore had the cylinder walls honed (I have photos) and slightly larger pistons were used. Millers glaze bust shouldn't have been needed, but it's never been pushed hard in the first 1000 miles, so it's possible it's glazed over. It's got 5w 30 fully synthetic in it, and from what I've read and heard it's not the best after you've had this work done. How true, I don't know.

Hi Danny. Funnily enough, when I rang him back today he said that there's something called Millers Oils Liquid Glaze Bust. It's mineral based and you only run it in for 200 miles then change the oil. He knows a few people that have used it and had good results. I'm going to try running the engine at higher load first for a while . Its automatic so it never gets high revs for a long time, but with it having the DSG box I'll put it into manual and push it harder and see if it makes a difference. If it doesn't, I'll try the glaze remover. He basically said the design of the engines is utter rubbish and they are just prone to glazing and passing oil. I'll let you know if I get sorted. Has anybody had experience of Millers Liquid Glaze Bust?

I just spoke to the company that did the rebore. He says the bore will be glazed, making it too smooth - due to not driving it hard enough. Harder driving supposedly burns off these deposits on the cylinder wall. I don't know if there is any truth in this, and how you then correct it. I'll be speaking to him again tomorrow so will let you know the outcome. Supposedly he knows of some additive that can sort it.

I don't honestly know the answers to this. Are you thinking that maybe contaminates have scratched the re-honed cylinder walls? Would you have any idea on how the exact cause of the new oil consumption could be determined without pulling the engine back to bits? Do you think there is any chance that everything is seating in? I have read on other sites that after engine rebuilds that oil consumption can go up, then sorts itself out (don't know how or why but I really don't know which way to take things now). The car runs beautifully. It's just so frustrating

It's never overheated, and there's no milky liquid in the oil. The performance is still spot on too. Do you think the head gasket may only be passing a little bit?

Hi, I've got a 2011 skoda superb estate 1.8 tsi petrol. I bought it with 81k on the clock 7 months ago . It was drinking oil (4 litres in 2000 miles). I took it back to the garage where I bought it from. The owner was extremely helpful. We knew (through this site and other websites) that the only remedy was engine strip down, rebore, then new pistons and rings. This was carried out free of charge. The guy who carried out the rebore said he wasn't surprised it was drinking oil as the cylinder walls were scored. After the rebore, he had re-honed the cylinder walls and new pistons were fitted. I took the car back to the garage after 150 miles and the oil hadn't budged. Great. I went back after a total of 300 miles and it was still exactly on the maximum. We were both happy it had been fixed. However, I checked the oil when I had reached 1000 miles and it was down to the minimum. I topped it back up to the maximum and have just checked it after 200 miles - down to the minimum. Does anyone have any idea why this could be happening as it seemed like the issue was fixed. I'm so frustrated. The garage owner has been fantastic. The car runs brilliantly and has done since I bought it. I love everything about the car, except the oil drinking. Help!

Here is a close up of the piston. Sorry I don't know manufacturer. I've done 500 miles since having the new pistons and rings. It hasn't drank a drop of oil. It would normally have had 1 litre by now. Job done.

Here is some photos of before and after the rebore. The total cost of taking the engine out, doing the rebore, fitting the new pistons and putting the engine back was nearly £2k. Luckily covered by the warranty.

I too bought an 11reg 1.8tsi skoda superb in June with 81k on the clock. Beautiful car, drove fantastic. Over a short space of time I realised it was drinking oil at a huge rate. I documented every time I topped it up and recorded the mileage. I used nearly 4 litres of oil in 2000 mile. I returned to the used car dealer I bought it from (Tynemouth Motor company) and showed him all the times I had topped up etc, and this forum about the 1.8tsi having faulty piston rings. He couldn't have been any better at dealing with me. I had took out an extended warranty and he sent my car away to Rosamund Rebores in Blyth, Northumberland to get the block rebored and new pistons and rings fitted, at no cost to me. I've had the car back about 2 weeks now and done 340 miles and the car hasn't used a single drop of oil. I consider myself incredibly lucky. If I'd seen this forum before I bought the car, I would never have bought it. The fault lies squarely with VAG. To wash their hands of this problem is a disgrace. I absolutely love the skoda superb, but when it's time to change it I won't have another VAG car. I'll be buying Japanese. It's a shame because previous to the superb I had a petrol octavia with 176k on it, and my friend bought it and uses it every day. I felt sick when I found out about the 1.8tsi. Hopefully people read this forum before parting with their cash.
