I asked and never did get an answer as to whether or not it was synthetic oil.
While new to the synthetic oils for automotive use, been using them for decades in comfort and process air conditioning and refrigeration applications.
Bust the seal on a gallon of those lubricants and you either use it or discard it. And it's a real pain in the ass to boil the water out of those, takes forever and a day if the system is large enough. Water in the oil those applications does a lot more than cause something to rust, in fact that isn't even an issue, the equipment won't last that long.
Besides in those pics it's obvious the oil was dumped after the engine was run which is going to make it look "milky" if there is any water at all in it. All lubricants will draw moisture from the air around it, who here doesn't change their oil in the spring anyway?.
I dump mine base not only on mileage but time, moisture being the exact reason for the time factor.
Even an engine running 24 hours a day can pick up moisture depending on the dew point and oil temp, seen it in the military which is why on a regular schedule we'd pump it from the sump to a centrifuge to remove water and particulates before sending it back into the sump.
About the only time it was actually changed is when fuel dilution lowered the viscosity. Which was tested at least once during a 4 hour watch whether the engine had been running or not (redundant BS IMHO most of the time, but that's what we did).
I agree starting an engine and not letting it come to operating temp isn't a good idea however not running an engine at all for extended periods of time IMHO would not be desirable either.
I'll risk the moisture to keep everything lubricated if nothing else. I'm going to change the oil anyway.
Besides, now that I'm in this I've got a lot of expensive test equipment on my service truck that will give me an idea on just how long it takes an air-cooled engine sitting at idle to come to temp just for a benchmark now that I'm thinking on it.
I'll guess mgosset1 is right when he says "not long". Seems to me my 2012 FLTRX goes into "parade mode" pretty quick.
Once I find out if it's doing that close to where it's suppose to, I guess I could use that as an indication. Disable it and wait for the cruise light to flash.
