If you always use premium fuel, will your vehicle have better performance?We’ve heard this question a lot. On some level, the logic makes sense. Instinct tells us that “premium” relates to quality and better quality means better performance.But the rating of gasoline does not relate to the quality of the fuel.The numbers on the fuel pump are a gasoline’s octane rating. They indicate the amount of pressure the fuel can hold up to without causing problems in an engine.Most engines will compress fuel before burning it. The cylinders press the fuel until it is the right density, then a spark plug ignites to fuel to create the energy to run the vehicle.A gas octane rating of 85 can handle less pressure than 89 octane, which handles less than 91, etc.Some high performance vehicles have engines that compress the fuel further than a standard engine. In these high compression engines, it is very important that you use the correct fuel with the octane rating the engine calls for.But if your engi ... read more
