My aunt purchased a 2010 Hyundai i10 1.2 petrol last year as she really wanted one of those. Car was great, 80k miles and even had heated seats! 4 months down the line she is complaining about losing oil and 'a garage' says it is not leaking and that is possibly valve stem seals or piston rings. Both of these sound feasible as she has said it has been topped up 3 times in 3 months (engine oil light has come on according to her). She is not mechanically minded and is around 50 miles away from me so I can't look at it to help her. I don't trust her local garage as they are guessing and have not investigated properly. Recently she came to visit and didn't top up before she came. The oil level was exactly the same as it was when she left, leaving me to think it can't be the seals? I know it needs a proper investigation but if the valve seals or piston rings were gone, would it not consume oil all the time? There is no smoke out of the back either, which I would expect if it was burning oil. Anything I can check or get checked? Any advice welcome as she has left it late and I don't want to go back to the seller (trade) and look an idiot.
