Which way to turn the fuel tank cap?

[MacCassidy]

The fuel tank cap is turned to the left to open, and to the right to close. Refueling is a routine task for every car owner. When refueling, it is important to choose reputable large gas stations and select the correct gasoline grade. Different grades of gasoline have varying octane levels; higher-grade gasoline has a higher octane rating, which provides better anti-knock properties. Gasoline is a volatile, flammable hydrocarbon mixture liquid derived from the distillation, cracking, or pyrolysis of petroleum. It is primarily used as fuel for spark-ignited internal combustion engines and consists mainly of organic compounds obtained from crude oil distillation and various additives.
