What is the best way to maintain the Kia Ceed engine's efficiency?

I have a Kia Ceed and I want to make sure that its engine is always performing at its best. What are the best practices I can follow to maintain the engine's efficiency and prolong its lifespan?

Regular oil changes and using high-quality oil will help keep the engine clean and functioning efficiently.

Don't ignore warning lights on the dashboard, as they could indicate potential issues that need to be addressed immediately. Regularly checking the engine's fluid levels is also important.

Avoid harsh driving habits such as accelerating and braking too quickly, as this can put unnecessary strain on the engine and decrease its efficiency.

Invest in a good air filter and replace it regularly to ensure that the engine gets enough clean air for combustion.
