    Google gets it done.

    The desired oil temperature range for Lycoming engines is from 165˚ to 220˚ F. If the aircraft has a winterization kit, it should be installed when operating in outside air temperatures (OAT) that are below the 40˚ to 45˚ F range.

    Steve,

    ... Looks like mine!

    Greg,

    I was barely seeing 140 deg without (OAT at the airport being high 20s/low 30s). With the oil cooler blocked I'm seeing 180 degrees.

    Oops, you did say CHTs ... these are oil temps obviously!

    Chris

    Not sure on CHTs, I don't fly in really cold temps here in Texas, usually low 30s is the lowest and I don't have a CHT gauge so maybe someone with CHT gauges can answer this question.
