How to extend the life of my Vauxhall Combo Life's engine?

I have noticed that my Vauxhall Combo Life's engine is aging and I want to make sure it lasts as long as possible. What are some maintenance tips and tricks I can do to extend the life of my engine?

Regularly change your engine oil and filter to prevent build up of harmful contaminants. This will keep your engine running smoothly and prevent any potential damage.

Monitor your engine's temperature and avoid running it too hot. Overheating can cause serious damage to your engine and shorten its lifespan.

Avoid harsh driving habits such as rapid acceleration and sudden braking. These put unnecessary strain on your engine and can lead to premature wear.

Keeping up with routine maintenance, such as replacing spark plugs and air filters, can greatly improve the longevity of your engine.

Incorporate a fuel additive into your gas tank to help keep your engine clean and improve its overall performance.
