That's correct, just giving him options.
While premium gas is "recommended" on many vehicles, it's not always "required."
Some cars that need premium need at least 91 octane, and others may require at least 93 octane. If the owner's manual recommends premium gas instead of requiring it, you can typically operate the vehicle safely on regular gas.
That's because modern cars have knock sensors that detects pre-ignition and simply retards the ignition to prevent damaging the pistons. Many people needlessly put way more expensive premium gas in their cars when it's not really required.
Published vehicle torque and HP values are based on using a specific octane. If you want your car to achieve those numbers, you want to use the fuel the manufacturer used during testing. For the most part, people aren't going to notice the difference between fuels, so you can often use regular fuel without any problem.
