It has been a complete pain having to check the oil for every trip, even multiple times within one trip! I've used over 50 litres of oil since May (approx. 5k miles)and there have been a couple of other related problems as a result. It's lucky I'm a fairly patient person.
That said I have no quibble with Autolusso, the fix has been a long time coming but Ned has kept me informed of progress with the insurance companies when asked, shown me the bad liners compared to the good ones and quickly sorted out the related problems when they occured. As Squadrone Rosso said, it was the third party machine shop that was at fault and not Autolusso.
