I bought my boat w/ the 150A Suzuki with only 30 hrs on it. Used it this season and have just pulled it for the season with 90 hrs. Suzuki recommends a 10w-40 blend, Suzuki - ECSTAR Marine V7000 10W40 4-Cycle Engine Oil - Semi-Synthetic, in my other boats I have always used Valvoline 10w-30 full synthetic, Valvoline 4-Stroke Marine Full Synthetic Engine Oil. I am boating in the North East, Maryland area should I get the 40 weight?

New to the forum and thank you for any help.
