Q:
A: 87 octane regular no lead is all you need.
The only difference between premium fuel and regular fuel is the octane rating.
Octane has nothing to do with the amount of energy in the fuel. High octane fuel will not give any significant increase in performance in a low compression engine. You do not see any benefit from high octane fuel unless you have a high compression engine.
The octane rating is the fuel's resistance to spontaneous combustion under compression. The higher the octane rating, the more compression it takes to make the fuel spontaneously ignite.
A high compression engine requires higher octane fuel to prevent detonation. Detonation is a condition where the fuel air mixture ignites while being compressed before the spark plug fires. Detonation can cause serious internal damage to an engine.
Your 1977 GMC Motor Home 454 engine has a 8.25 to 1 compression ratio. You don't really need to use a higher octane fuel until you go over 10 to 1 compression or if the engine is equipped with a turbocharger or supercharger.
In some instances an engine will not run as well on higher octane fuel. This is because higher octane fuel has a slower burn rate. If it is not compressed enough before it is ignited the fuel may not completely burn in the combustion chamber of your engine. It would finish burning in your exhaust system where it does absolutely no good.
The higher octane fuel will not make your engine run any better or last any longer. You are only giving the oil companies more money than you need to. I think they make enough money already.
