Was reminded today of the 7 day run to maintain oil film and fuel wetting of components , and a log book entry to back it up, any failure to do it, ie storage or heavy maintenance rendered it unservicable, you can vent it up to 3 times but then it goes back for overhaul.
potential sellers and buyers and reps are told to look for these entries .. or steer clear of ship as its 60K min charge to have a look at it otherwise.
