Hello... And thanks in advance for any advice anyone can offer me on my question

I bought a 1970 BSA Lightning last year and I recently read on another forum about using a lead fuel additive for older British bikes. I have a 4-gallon tank and have been putting premium unleaded in it before now. Can someone suggest a brand they think is effective? And how much would I use for a large gas tank?

Thanks!

Well, after over 30 elaborate responses, we have an answer to a simply question.
Do our BSA engine require an additive?
The answer is no! 91 octane works fine.

The wizards have spoken.

and yeah, those additives are a joke

I run Avgas in all my machines. Cleanest plugs ever. No deposits. Avgas here right now in this valley is $4.25 to $4.95 self service. Avgas has a long shelf life and doesn't stink bad like pump gas.

yep.... leaded gas is a different thing... the engine will run different.... like it was designed to actually. its hard to believe that there are people that have never used leaded fuel but then there has been no leaded auto fuel in the USA for almost 40 years
