Oil viscosity.......

[legotech7]

Some had suggested that I run 20w-50 in my 1641... Isn't that too heavy an oil for that engine?. I usually run 10w-40. I live in the Carolinas and the weather here is rather mild in the winter.. Sometimes it gets really cold, but I think that 20w-50 is a bit thick.... Any suggestions on what oil might be best?..... Thanks.................
