Web Forum for Singer Cars

Thanks for advising regular unleaded with lead additive and something to eliminate alcohol. I tried premium unleaded but it is making the car backfire. I’ll let you know it that resolves with lead and alcohol remover.

I just bought a 1955 Singer 4AD SM with duel carbs. Wondering what type of fuel I should be using? Non alcohol; high octane at regular gas station; put additives into fuel? Any suggestions?
