The 20w-50 is fine until temperatures are consistently well below
freezing.

Subject: thicker oil viscosity question

this issue may have been beat to death in the past, however I need to
revive it for just a moment.  I was given Castrol 20w50 motor oil
recently.  The weather is beginning to warm a bit to now a high of 72.
Is this still too low an ambient temperature to use 20w50 or should I
wait until the temperature reaches the 80-90's (82 air cooled engine)?
Also is a thicker oil more appropriate for the air cooled engine?
