If your car doesn't ping using regular, then there's no reason to use premium. The anti-knock level is just fine for your engine. 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.

Does premium fuel clean your engine?

All grades of Shell Gasoline provide unsurpassed protection against gunk. Gunk is another name for carbon deposits that can build up in engines running on lower quality gasolines and act like a sponge in your engine, absorbing and trapping gasoline, and making combustion less efficient.
