They suffer from Carbon build-up in the cylinder which can then lead to friction>heat>cracked cylinder>rebuild lol. The engine was designed to be revved, hense why they're not that torquey, so whenever you rev it high it helps to breakup the carbon and flushes it through. Same as any engine really I suppose but more than usual 
Essentially these engines are capable of the same mileage as a normal piston engine, but that requires it being looked after as designed from release, and the chances of every owner putting in the time and effort is very unlikely... I do however have it on good authority that the previous owner, even though he didn't drive it much, did baby this car so that's good
