: What kind is best and how much per gallon. Ihave 6 old ones and know unleaded gas doesnt make it
I haven't tried this yet, but a friend of mine uses in his truck which was designed for leaded gas one quart of GM type automatic transmission fluid per 20 gallons of gas. Ford ATF doesn't work. He says he's gone 40,000 miles without head trouble since he's been using it. With lead substitute, he was pulling the head every 20,000 to replace valves. I have been using various lead subs in my tractors, but they still have valve wear problems, except for the F-20.
