It's time to change oil in my 27 Tudor. I've been using 20W non detergent, and throw in about 1/2 to a full qt of transmission fluid for smoother shifting (advice of an 83 year old mechanic) and it's always ran well, but given all the talk about zinc being removed from the oil, wondering if I should add a zinc additive this change... any thoughts? what's everybody else using? less than 30 hours of operation on engine and transmission completely rebuilt and babbitted, new pistons, rings, valves, bands etc
