Hi everyone. Many thanks for all the responses. As I'm not exactly sure of the engine history I think the best course for me to follow is to... 1. Drain the tank. 2. Refill with high (97/98) octane fuel 3. Use Castrol lead replacement, certainly for the next 500 miles or so, maybe longer.   Anyone violently disagree  ?   Thanks again folks..  

Hi All I just bought a 1966 Vitesse Mk1 convertable that started off it's life as a 1598 but in the late 70's was upgraded to 2Ltr. The car is running very smoothly, needs some body work but is in a reasonable condition. My question is about fuel/Petrol 1.  What the best for this age vehicle ? 2. How can I fathom out what is already in the tank ?? Any help or advise would be really appreciated. Thanks,,  Alan.
