Interesting, thanks. So your view would be the occasional morale boosting start up will do not significant harm.
As to running in, I wnder what "load" does to the pistons, as they only go upand down, so I would imagine revs more than "load". Towing a tractor woul still only require an up and down motion. So there must be more science to it than I can appreciate.
But can definitely see that the operating temperature will make a difference to the oil flow and movement of parts. Would an oil pre-heater make sense? I have seen them advertsied for winter use, so any thoughts please?
