How long does premium gas last?

In general, pure gas begins to degrade and lose its combustibility as a result of oxidation and evaporation in three to six months, if stored in a sealed and labeled metal or plastic container. Ethanol-gasoline blends have a shorter shelf life of two to three months.

Should I switch from premium to regular gas?

Can I use regular gas if my car requires premium? Experts advised against switching to regular gas if a vehicle requires premium.

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

What happens if you mix premium and regular gas?

Can I mix premium and unleaded gas? Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.

Higher octane fuel will not offer any better fuel mileage, increase engine horsepower, or make the engine start quicker. Higher octane only increases the likelihood that the combustion will be controlled, and your engine will perform as it was designed.

What type of cars need premium gas?

Cars that require premium gasoline have high-compression engines, turbochargers, and other high-performance aspects. Not using premium won't necessarily hurt your engine, but you could lose some of the performance of that premium engine you paid for if you use regular or midgrade gas.

How much does premium gas improve mileage?

Why is premium gas still so expensive?

There are several potential reasons for the shortfall, including the fallout of Russia's war in Ukraine, the impact of U.S. environmental regulations and a lack of refining capacity. The net effect is that it's making the fuel even more expensive than usual, when compared with regular unleaded.

Why is regular gas cheaper than premium?

Octane Ratings

The lowest grade is regular, and the highest is premium, while everything in between is considered mid-grade. Premium gas will always be more expensive than regular. Octane rating is an indicator that shows how this particular gasoline resists pre-ignition of the air-fuel mixture.

Does premium gas clean your tank?

No matter what you've heard, premium-grade gasoline won't do more to clean deposits from your fuel injectors or other parts of the fuel system because today's regular gas contains the same detergent additives.
