Multi-turn user requests:
user: I'm cruising down a country road in my brand-new convertible, admiring the scenic lavender fields when I notice the fuel gauge creeping towards empty. I'd appreciate it if you could refill with 10 liters of gasoline to keep the adventure alive. Use 2 decimal digit of the gallon amount
user: Now that the tank is replenished, let's fire up the engine with a swift ignition and take a peek at the dashboard stats, particularly the battery voltage and the AC temperature before we continue our picturesque journey.
user: Before we venture further into the rolling hills, I'm keen on ensuring the tires' health is up to standard. Could you check the current tire pressure for each one and let me know?
user: To wrap it up, what's the average tire pressure? I want to make sure everything's in tip-top shape.
