Oil?

[urbanista]

I go with 10W-40, I believe that's what the manual said. And I use the Castrol brand, for no particular reason other than that I read somewhere that someone used it.

Any suggestions on the relative merits of switching to a different oil for the cold months? Here in DC winter temps may drop below freezing and I've read that a lighter oil is better in colder weather.

This newbie would definitely appreciate your suggestions.

run the 5w40 in the colder months (if you are expecting sub 32 degree F temps) that 10w40 is actually for temps above 32 degrees F if you get into the temp oil charts. I run the 10w40 in those sub freezing temps because mine runs 15w40 per mfg recommendations, every engine mfg usually has a chart of acceptable oil viscosities vs temps for their engines.
