Mine has steadily deteriorated. At the start of lockdown a c.13 min drive once a fortnight kept it operational, now it's down to needing a c. 13 min run every two days. The start/stop on the octys are a bit odd in that it will kick in when there's a warning on the dash saying 12v battery low, charge by driving. Also, unlike other start/stop cars I've encountered (not many to be fair) it kicks in before the engine heats up, at least in normal circumstances. I hate the idea of burning diesel for no reason other than to satisfy the whims of the mechanically propelled vehicle hence the temptation to go and earn a few ton.
