So is Higher Octane Fuel More Efficient? In a word, no. On its own paying for premium gasoline does not make your car run better or get greater gas mileage. Giving your car the fuel it requires to run smoothly and efficiently, without damage to the engine, does make a difference in your fuel mileage.
It is perfectly fine to use a higher-octane fuel than the manufacturer recommends for your car – though it’s unlikely to offer any discernible benefit. The only guarantee is that it’ll cost you more.
Will I get better mileage with premium gasoline?
Premium gas gives you more miles per gallon than regular gas. In actual fact, you’ll get a greater range of fuel economy between different brands of regular gas, than you will between the same manufacturer’s regular and premium gasses.
Does premium gas last longer than regular gas?
Sadly, there’s nothing in premium gasoline that would make it last longer than other fuels from the pump. Since the distinguishing feature is the higher-octane levels, the only real benefit you gain is lowering the chance of engine knocking, which isn’t much of a threat on most modern fuel systems.
Does 93 octane improve MPG?
At triple-digit speeds, the higher power on 93 octane gave the Charger an advantage measured in tenths of a second. The Dodge also posted a 0.3-mpg improvement on premium with its average of 23.5 mpg.
Will premium petrol improve your car’s performance? If your car has a 100 horsepower engine, that is its power output. Using a fuel with a higher octane rating won’t increase that output. It may increase its economy but the margins are likely to be so insignificant you won’t notice them.
Is it worth paying extra for premium fuel?
If you drive an ordinary mainstream car, then there’s not much point in paying extra for premium fuels. Your car has been set up to work properly using standard petrol and diesel, and fuel companies have created their regular gas to work effectively in your engine. • Should your next car be petrol or diesel?
Does premium gas make your engine last longer?
Even so, many drivers think that giving their engine a “special treat” will help it last longer. Premium gas costs more and has a higher octane rating. Therefore, people often think it’ll reduce engine wear. While a tank of premium may help an engine in other ways, using premium fuel once in a while doesn’t really make sense.
It just means you won’t get the same performance or fuel economy if you use a lower grade gas. Even if you car runs on regular, an occasional tank of premium isn’t completely a bad idea. Higher octane fuels often have a higher-quality additives put in at the refinery.
Premium petrol usually has a higher octane rating than regular petrol. Octane is a chemical component of petrol, and the amount of octane contained within the fuel determines how well it will work in higher compression engines – high octane fuel works more effectively than lower rated fuels.
