Transfusion
While the oil level has been fine, I decided that since I had no idea when it was changed last, to drain and change the oil. After some research, I decided to use Lucas Classic Car motor oil for the first change, at a 10W-30 viscosity. You can view the Lucas Oil specs for their Classic Car 10W-30 here. I decided, after doing quite a bit of research, to use a high-zinc oil. While high zinc primarily protects babbit bearings, even if you don’t have them, the zinc helps the older engine bearing surfaces. I had found good reviews of the oil, so decided to purchase 6 quarts.
