What are the benefits of premium gas? Premium gas has a higher resistance to engine knock in luxury and performance vehicles with turbochargers or high-compression engines, so you can hit that horsepower smoothly.
Should you use premium gas in your car?
If your car only recommends premium, the choice is yours. With certain vehicles like the Ford F-150 and Mazda MX-5 Miata, automakers recommend premium gas but don’t require it. Research by AAA found that these vehicles saw a slight increase in performance and fuel economy using premium gas.
Is premium fuel worth it?
If you are a casual motorist, you may have noticed the premium and high-octane fuels for sale at the petrol pumps and wondered if premium fuel is worth it. With promises of better efficiencies, cleaner engines and smoother driving, it’s no wonder these products demand a premium price.
Why do turbochargers use premium fuel?
It turns out that turbochargers respond really, really well to the use of ‘premium’ fuel because it allows them to turn up the boost without worry about detonation. The better the knock resistance, or octane rating of the gasoline that is used, the more boost can be safely run in a given engine, and the more power produced.
What is the difference between premium and regular gas?
Your wallet might thank you. So, what’s the difference between premium and regular gas? Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates.
Does premium fuel last longer?
This means that it should burn less quickly whilst delivering more power, but it probably won’t last for a noticeably longer period. If you need to save fuel, you should consider other methods instead of paying more for premium fuel.
Does premium gas last longer than regular gas?
However, ethanol free premium gasoline lasts longer than regular gasoline with ethanol. But the same can be said of ethanol free regular gas, as compared to regular octane gasoline with ethanol. So the question of whether premium gas lasts longer than regular gas comes down to whether the premium gas contains ethanol or not.
How long does gasoline last in a gas tank?
The answer is thankfully simple, as gasoline lasts about as long in a gas tank as long as it does in a gas can. Pure gasoline in a car’s gas tank should last for about 6 months, ethanol gas for up to 3 months, and fuel-stabilized gas for 1 to 3 years.
What is the difference between premium petrol and regular petrol?
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.
Can you buy premium fuel with ethanol?
Some gas stations do sell premium fuel with ethanol. If the premium fuel you buy contains ethanol, then it has the same short shelf life as regular octane gasoline with ethanol. However, ethanol free premium gasoline lasts longer than regular gasoline with ethanol.
How much HP does 93 octane add?
When switching from a 91 octane tune to a 93 octane tune you can expect to see an increase of 5 to 6 more horsepower on top of the gains you are already getting from an 87 octane Bama tune.
Which cars run on 93 octane fuel?
Vehicles such as the Ford Escape and Mazda 6 are advertised with power figures made on 93-octane fuel, although both companies are quick to note that these vehicles will happily run on 87. What automakers rarely say is what, precisely, are the benefits of paying for premium. That ambiguity can be expensive.
Is 93 octane better than 87?
Just an equivalent to octane in points above and below Octane. As I learned there is more energy available in a gallon of low octane fuel say 87 vs 93 where as there may be more power available with the 93 at the expense of mpg and more mpg per lower octane!
Does a 93 octane Dodge Charger get better 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.
How does higher octane fuel affect engine performance?
When higher-octane fuel is flowing through its injectors, the engine controller can take advantage of the elevated knock threshold and dial in more aggressive timing and higher boost pressures to improve performance.
