The Opel Astra GTC 2016 typically requires 5W-30 full synthetic oil. Always check the owner's manual for the manufacturer's recommendations.

The recommended tire pressure for the Opel Astra GTC 2016 is typically 32 PSI for the front and 30 PSI for the rear tires. Check the sticker on the driver's side door for specific values.
To replace a headlight bulb, open the hood and locate the back of the headlight assembly. Remove the protective cover, disconnect the electrical connector, and release the bulb retaining clip. Replace the bulb and reassemble.
A squealing noise when braking is often due to worn brake pads. Inspect the brake pads for wear and replace them if necessary. It could also be caused by dirt or debris on the brake rotors.
To improve fuel efficiency, maintain proper tire pressure, perform regular maintenance, drive at steady speeds, and avoid unnecessary idling. Removing excess weight and using cruise control can also help.
Difficulty starting can be caused by a weak battery, faulty starter motor, or fuel system issues. Check the battery charge and connections, and listen for unusual sounds from the starter. A thorough diagnostic may be necessary.
To check the transmission fluid, ensure the car is on a level surface and the engine is warm. Locate the transmission dipstick, remove it, wipe it clean, and then reinsert it fully. Remove it again to check the fluid level.
Common causes for the "Check Engine" light include a faulty oxygen sensor, loose gas cap, malfunctioning catalytic converter, or issues with the ignition coils or spark plugs. A diagnostic scan tool can help identify the specific issue.
