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. |

My limited understanding is that higher octane fuel does not burn as easily as lower octane. So putting high octane in a low compression motor is basically useless. Don't know how common low octane ethanol free gas is though.
