How can I extend the life of my Volkswagen Golf engine?

I recently bought a used Volkswagen Golf with a high mileage and I want to keep it running for as long as possible. What are some tips I can follow to extend the lifespan of my engine?

Regularly change the oil and oil filter according to the recommended schedule.

Use high-quality gasoline and consider using a fuel additive to help clean the engine.

Keep an eye on the temperature gauge and address any overheating issues immediately.

Avoid frequent short trips and instead try to drive your car for longer distances at a time to warm up the engine fully.

Regularly check and top off all fluids, including coolant and brake fluid, to keep your engine running smoothly.
