However, OLDER engines (made before the introduction of unleaded gasoline) do not have hardened valves and stem seats. They require the lubrication provided by leaded gasoline. Unleaded gasoline is more expensive to produce for the same octane. Additionally, it requires more crude to produce the same octane as unleaded. (signed) Speed Racer
