What kind of gas does cars use?
Gasoline is rated by octane. Generally, regular is 87 octane, mid-grade is 89 octane, and premium is 91 or 93 octane. Octane ratings indicate the gasoline’s resistance to pre-ignition.

In many cases, the answer is probably no — you’ll likely be able to use regular fuel with no noticeable issues except for minor losses in performance and gas mileage. If your owner’s manual says that premium fuel is required, then you should do it, but your car won’t blow up if you occasionally opt for regular.
