Vdub: to Lead or not to Lead?

Hi John, I've been to many classic car shows and stands across the UK and one topic with huge confussion I face is the story of adding lead to classic air-cooled Volkswagen engines. To my knowledge Vdubs didn't need a lead additive once leaded petrol became unavailable due to they're harden valves in 1967 but what is your opionion. I spoke to a Millers Oil agent and he recommended using the lead additive in my bug, so I decided to use it on a tank of petrol. I noticed that the engine started up better and sounded easier but could this be true, I'm unsure if it really needs it?

On this, I can confirm that Volkswagen Beetles of this age *can* run on unleaded, as it's a car designed to be sold in the US market, and has hardened valve seats. If you encounter any rough running or pinking, just get the timing advanced a couple of degrees. Failing that, you can buy Octane booster from someone like Millers.
