[Mgs] Petrol

[Max Heim]

I am using premium exclusively in my '66 B. It has a Gold Seal motor in 18GB spec with approx. 95K miles, and a fresh head (<10K miles). “Premium” around here is 91 octane with 10% ethanol, so it still pings occasionally on hills. I’m running a newly reconditioned points distributor, and trying to dial in the optimal timing.

Later models with low compression engines might very well run on regular.
