Does premium gas burn slower?

Because higher octane gas burns slower, it is more resistant to knock when subjected to higher RPM and cylinder pressures. Compression ratios also factor into cylinder pressures. Higher ratios cause higher cylinder pressures and therefore cause the engine to be more susceptible to pre-detonation or knock.

Does premium gas give better 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.

Costco gas is high quality. Top Tier certified, just like Shell. Costco’s gas being “Top Tier” certified is the key.

What happens if you accidentally put regular gas instead of premium?

If you mistakenly fill up with regular fuel, your car’s ECU will adjust engine timing and performance to work with the lower-octane fuel.
