Does 89 octane 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.

Does 89 gas make a difference?

Let's start with the easy one. Most cars on the road recommend a standard grade 87 or 89. Premium gas 90-93 is completely okay to put in a standard vehicle. Car experts say there is no risk of damage to a standard car using premium fuel.

Does higher grade 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.

Why is 89 gas better?

A higher octane gas won't ignite as quickly, which explains why high-performance cars with high compression engines often require higher octane gas. Engines that take higher octane fuel tend to work more efficiently and emit less emissions and exhaust. It is important to use the required octane for your specific car.

Does higher octane gas give you better gas mileage?

Premium gives better gas mileage

Because premium gas has a higher octane rating than midgrade or regular gas, it produces a little more power when burnt. Designed for performance cars with large, powerful engines, premium also helps minimize the risk of preignition inside highly-stressed, hot engine cylinders.
