What Engine Oil to use????

[Jim Rainer]

Frank, I have the same engines. I use AeroShell 110W 9 months of the year and 15w-50 for 3-4 months in the winter. Our temps are muich harsher than yours in the winter. I'd like to use 100 year round but decided it was too hard on the engine. With no temps below 40 you can most likely use it use it year round.
