Should I use premium gas?

If your car doesn't ping using regular, then there's no reason to use premium. The anti-knock level is just fine for your engine.

What is the difference between regular unleaded and premium?

Regular gas has the lowest octane rating, Premium has a higher octane and Super (or Supreme or Premium Plus) has the highest octane. Octane is the measure of the fuel's ability to resist “knock”. Knocking or pinging are the loud noises that occur when the air/fuel mixture is incorrect.

Does premium gas 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.

What octane was premium leaded gas?

Regular unleaded is rated at 87 octane, the middle grade at 89 and premium at 92. Regular leaded is 88 octane. All new cars sold in the U.S. since the 1975 model year have a catalytic converter, which substantially cuts exhaust pollutants.

Why is avgas so expensive?

It's much higher grade, so it costs more. It's a specialist fuel made in much less quantities than other fuels, so a premium is added to ensure a profit.

Does premium gas burn slower?

Fuel with an 87 octane rating burns more quickly while higher-octane fuels burn more slowly. In engines designed for standard unleaded fuel, efficiency and performance is optimized for 87 octane and could actually perform worse with higher-octane fuel since the burn rate is slower.

Can you put 93 in a car that takes 87?

Can You Mix 87 And 93 Together? In addition to 95 octane fuel running through the 87 or 89 octane engines, you have absolutely no harm to your engine. The 93 octane fuel will not need to be run in any circumstances. In fact, it won't improve how your car runs.

However, mixing these gasoline types in cars designed for premium gasoline may result in engine knocking and damage to the fuel system depending on the car.

Does premium gas burn cleaner?

Higher-octane juice won't reduce pollution or emissions at all, according to a study recently done by the American Automobile Association. Fewer than 20 percent of the cars on the road today have engines designed specifically to burn premium gas, which is what they should be running.
