Have you ever pulled up to the gas station and wondered whether or not you should be using those higher grade premium fuels? Well wonder no more! Mayfield Toyota is here to break down the difference between fuel grades and which one is best for your Toyota. So read on, and who knows, you might just save yourself some money!
Premium? Regular? What’s the Difference?
All fuel is divided into “octane”, which is the percentage of isooctane in the fuel. This means that if regular fuel is 87 octane, it is 87% isooctane. Premium fuel is typically 91 octane, meaning it is 91% isooctane.
Quite simply, isooctane is what your vehicle burns in order to run your Toyota. The higher the grade of fuel, the more isooctane is has, and the more energy the fuel releases when burned.
Which Fuel Grade is Best?
Which type of fuel is best? Well, that depends on your vehicle. Modern engines are smart and can handle a wide range of fuels, meaning your Toyota can run on either regular or premium fuel. However, certain vehicles (typically high-performance vehicles) are designed to take advantage of the higher octane rating in premium fuel. Because premium fuel releases more energy than regular fuel, a vehicle running on premium will produce more horsepower, run smoother, and offer increased throttle response.
Should I Switch to Premium Then?
Not necessarily. Remember, only engines designed to run on premium fuel (like a Lexus IS) will see the benefits. Filling a vehicle (like a Toyota Camry) with premium, when it has been designed to run on regular, will result in only minimal improvements – certainly not enough to warrant the extra cost. Check your owners’ manual, or inside your vehicle’s gas flap to see which grade of fuel is recommended, and stick with it.
