My comment regarding cold temperatures dealt specifically with an occurance
last year when the temperatures in my region were consistantly below zero
for over a week. On the coldest morning of the lot, early, I tried to start
my bus to no avail. My battery and all systems were in great shape, but the
motor oil had turned so thick that the engine would BARELY turn. The
solution involved draining the motor oil and replacing it for the remainder
of that winter with a thinner oil.
20W50 is quite thick at or below 0*F.
Put a bit of it in the freezer sometime (even at 32*F) and watch just how
smoothly it pours.
