I've just been given two conflicting suggestions:

Run non-ethanol 89 octane gas and use a lead substitute (instead o' lead)

or

just use modern 91/93 octane gas that contains ethanol.

I had been using non-ethanol gas in my 72 Beetle and then switched to modern 91/93 gas with ethanol and it seemed to develop a hesitation on acceleration.

I just got a 71 914 and am interested to know what you all are using so I can decide which gas to use in it.
