 - Create a `HybridCar` class that extends `Car`.
 - It will need variables for both battery level and fuel level
 - Implement `Refuelable` and `Chargeable` together
-- (Optional) Override methods to manage both power sources (driving drains battery first, then gas)
+- Service logic for HybridCar:

+needsService(): return true if mileage > 10000
+performService():
+Print "Engine oil changed and battery system checked"
+Reset fuelLevel to 100
