If you are worried about forgeting it, use a timer and set for 30 minutes and check
oil temp by pulling the dipstick--If you have a
oil cooler mounted in the nose, put a small heater/fan in front of it like one out of a bathroom overhead deal--nutone has a unit for about 75 dollars at home depot that has a heater/fan unit that you can remove with one screw--evan has a normal 110 plug on it-
Even with preheating the
oil in a wet sump you still have to pump thru the remote filters and cooler/lines before the warm thinner oil gets to the cold block/crankshaft.
For winter storage/starting/driving maybe try a 0-30 wt oil?????
