I'm pretty careful to keep the bar out of the dirt . I'd rather switch saws
then swap or sharpen the chains when I'm done for the day . I only have one
spare for each saw , but I keep them sharp in case I get stupid . Around
here if you touch dirt there's a pretty good chance there's a rock there ...
there is a reason they called it Stone County .

Saw vendors generally recommend SAE30/20 for summer/winter as acceptable
if specific bar oil isn't available.
I've used the old tractor oil (5W40 CF+) with an addition of about 1:4
to 1:6 STP or the like as a "sticky-ifier" for 20 yr or more. Seems
I do filter the oil through paper filter when storing and let set and
decant the top for use to minimize any particulates.
I have (and do on occasion still) buy/use a commercial bar oil if happen
to run across a buy, but when a tractor change (on 100-hr intervals on
some) is 18 qt or more, seems a real waste for such low pressure usage
to just toss it...
