1978 S1 does it take unleaded?


Recommended Posts

Guys,

Perhaps a stupid question but I couldnt find any reference to it when searching ...

I think my 1978 S1 esprit was specced to take leaded petrol, Im not sure if this is 'must take' or 'best to use'. Could someone confirm if I would need to use additive to stop the valve seats from burning out or any such thing? Did the later ones get changed or is it the samne head?

If it must take leaded, is it worth or possible to get the valves done to take unleaded? anyone done this or know if it is possible? or should I stick with the snake oil additive and unleaded?

cheers

Frank
