Frequent question: Does premium gas make your engine last longer?

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.

Is premium fuel better for your engine?

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.

Does higher octane gas last longer?

93 octane fuels are more refined and contain more stable hydrocarbons. These stable hydrocarbons can last 2-3 times longer than 87 octane fuel. Even in proper storage 87 octane gas can start to degrade in 3 months, 93 octane fuel should last closer to 9 months before degradation is noticeable.

What happens if you put 93 instead of 87?

If you usually fill your tank up with 87-octane gasoline and you accidentally put in a higher octane blend (say, 91, 92, or 93), don’t worry. You’re actually filling your car or truck with a different blend of gas, which means it will burn differently in your engine.

Can I damage my engine with higher octane?

The higher octane gives premium gas greater resistance to early fuel ignition, which can result in potential damage, sometimes accompanied by audible engine knocking or pinging. … It’s the fuel’s ability to be compressed more without pre-igniting that results in more power when used in the appropriate engine.

Which is better 95 or 98 octane?

98 petrol, which is more stable and resistant to ‘knocking’, is a better choice when it comes to engine protection. 95 petrol works as well, but if your engine is powerful, it will use higher pressures that 95 petrol may not be able to withstand. … In the long run, 98 petrol wins out for engine protection.
