Dear Jack,
I've recently purchased a 1988 Alfa Romeo Sprint 1700 coupe (twin carb model). Does this vehicle require a fuel additive such as fuelmaster to protect the valves, or are the valves hardened and able to run on unleaded petrol? I'd be grateful for your advice.
Many thanks,
Rob Miller
I suspect no fuel additive is required but I suggest you make contact with a Alfa car club to confirm.
