In Reply to: 20-50 Oil in my 230 ci Flathead? posted by J-Gilly on Monday, January 07, 2002 at 6:19PM :
I use 20/50 with no problems. My 230 is sorta tired and the heavier goo keeps good oil pressure at idle when hot.
Just a caution, when it's cold out, like 40 and lower, (Wisconsin) keep the revs very low like 1000 rpm until the oil is warmed up by the engine. This will minimize aereation of the oil. Below freezing I would run a lighter weight, but my garage is always above 40 degrees.
