What is the best fuel octane for The fiat 124.
different octanes have the same potential energy , if the motor knocks , which I doubt , then use a higher octane . Years ago this guy was saying "get aircraft fuel and your car will go faster " well aircraft fuel is kerosene , and it does have a very high octane , but don't put it in your tank
No that is jet fuel not avgas
