2017 Toyota 4Runner - Premium fuel

This is what the owners manual states about using 87 octane fuel;

You may occasionally notice light knocking for a short time while accelerating
or driving uphill. This is normal and there is no need for concern.

I wouldn’t be concerned with octane with modern vehicles, they all have knock sensors that are necessary to control the oxides of nitrogen that might exceed federal standards if pre-ignition were allowed to occur.
