    You are running too cold–Move up to 180’s

    What temps is she holding on the troll?

    Do you also do a lot of higher speed running?

    Probably————–You might consider going to 180F stats .. I’ve done of a few Low speed users and the difference is amazing in overall performance, engine oil staying water free under the valve cover, and engine exhaust cleanliness.
