----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]----Dave, you are talking about aviation 15W40, aren't you? Phillips or Aeroshell or one of the other aviation brands? Never use automotive or diesel oil in an aircraft engine. Liquid cooled engines have much lower clearances than air cooled engines. With the high clearances, oil must be especially formulated for them. Ashless dispersant oil is best. 15W40 aviation oil should be fine for winter and summer use.
