Imagine it is 1955...think of the automobiles that were available at the time tell me what oil you are using. I think I'm changing oil every six months, and I'm using Union 76 Royal Triton SAE 30 in the warm months and RT SAE 20 in the winter. I'm also probably driving a late forties Chevrolet sedan with a babbit bearing inline six.
