WHich gas to use??

Hi, I'm brand new to Bimmerfest and brand new to classic BWM's too. I took delivery of my 1972 Bavaria today which I thrilled about. Just to prove how new I am my question is ........ what type of gas can I put in this car??? I've just moved from Europe to the US and not sure if i need to add a lead substitute to regular gas or not. Anyone out there know?
Many thanks

Use highest octane available. Valve saver / lead replacement has not been necessary in my 86 735i or 89318i combined at over 700,000km.

Thanks for your reply.
Had to take a chance before I got your reply as was completely out of gas ....so filled up with regular. Car appears to be running fine but will follow your advice when fillin up next time.

Any 'Regular' = DEATH to BMW engines. Here in Australia we are lucky and get 98octane as the top fuel product (BP/Shell/Caltex/Gull). I never buy anything else - even for my mower! Steer very clear of Regular and you will do fine. Good luck with your oldie!

Well, you can go for octane
