Is Premium Gas Better For Your Car? Premiums are typically higher in octane rating – 91 or higher compared with 87 regular octanes. In contrast to lower-octane fuels, premium fuel's higher resistance to early fuel ignition can result in possible engine damage with a loud knocking or ping while the engine is running.
Will premium gas hurt a regular gas engine?
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.
What happens if you put premium gas in a regular car?
That said, putting premium gas in a regular car won't hurt it. But you'll certainly spend more per gallon, and your regular car won't get better fuel economy with high-octane fuels. Ideally, any car with a high-compression engine or parts, or even turbochargers, deserves premium gasoline.
Why you shouldn't use premium gas?
The main difference with premium is its octane rating — 91 or higher compared with 87 for regular 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.
Is premium gas better for your engine?
The difference between regular and premium gas is in the octane rating. In most states, regular gas has an octane rating of 87, while premium has a rating of 91 or 93. The high octane in premium gas provides greater resistance to engine knock, which happens when the fuel-air mixture in an engine combusts too early.

And today's advanced engine controls adjust the engine's timing and fuel mixture to compensate for differing octane levels to prevent pinging or knocking. Many cars only require regular gas.
Can high octane fuel damage an engine?
As premium gas is higher in octane, it is more resistant to early fuel ignition, which can result in potential damage, including engine knocking and pinging.
Is premium gas worth the extra price?

Does premium gas last longer than regular gas?

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.
