It is best to avoid ethanol additions as much as possible.<span class="m_6120575802208623400apple-converted-space"> </span><br>
In the Netherlands we still can choose between 5% or 10% ethanol.<span class="m_6120575802208623400apple-converted-space"> </span><br>
Premium fuel 5% is the best and offers the least chance of damaging the old type of fuel lines - hoses and gaskets in the carburettors.<span class="m_6120575802208623400apple-converted-space"> </span><br>
It also offers 98% octane, which had the least chance of pings.<br>
The final advantage of 5% ethanol is, that this fuel has a higher energy content, which gives a better mpg figure.<span class="m_6120575802208623400apple-converted-space"> </span><br>

I even use 5% ethanol premium fuel in my daily driver Mazda 6, which gives a nice fuel economy and a clean fuel system.<br>

<br>
As already said if you have a low compression engine then lower octane should be fine. If high compression then you will get the benefit of better performance and economy with higher octane. Low ethanol is better in both cases.<br>
<br>
Because the fuel today is so different to when these cars were first produced the original timing specs are no longer relevant. If you get pinking then back off the timing until you don't at any combination of throttle opening, revs and load. With high compression
and high octane try advancing bit by bit until you get pinking, then back off a bit till you don't.<br>
<br>
You are less likely to get pinking on low compression even with low octane fuel, so if you can run the book figures for timing without pinking then do so. You might get a bit better by advancing, but you can advance so far that it stalls the starter but still
doesn't pink. That's obviously too far.<br>
