How to maintain the Volkswagen Polo's engine for long-lasting performance?

I have recently purchased a Volkswagen Polo and I want to ensure that its engine stays in good condition for a long time. What are some tips to maintain the engine and ensure optimum performance?

Regularly change the oil and oil filter to prevent build-up of dirt and debris in the engine. This will also ensure that the engine stays lubricated and functions smoothly.

Invest in a good quality fuel and avoid filling up the tank with low-quality or contaminated fuel. Poor quality fuel can cause damage to the engine.

Get the engine checked by a professional technician at regular intervals. They can identify any potential issues and fix them before they become major problems.
