How to maintain my Toyota Highlander's engine?

I recently purchased a Toyota Highlander and I want to make sure I am properly maintaining the engine to ensure it lasts for a long time. Can you provide some tips or advice on what I should be doing to keep it in good condition?

Regular oil changes are crucial for maintaining your Highlander's engine. Make sure to follow the recommended interval in your owner's manual.

In addition to oil changes, have the air filter and spark plugs checked and replaced if needed. These are also important for keeping your engine running smoothly.

Don't forget to also check your coolant and transmission fluid levels regularly. Low levels can cause damage to your engine over time.

If you are experiencing any unusual noises or vibrations from your engine, it's important to have it checked by a mechanic as soon as possible. Ignoring these warning signs can lead to costly repairs down the road.

Lastly, make sure to drive your Highlander at a consistent speed and avoid unnecessary idling. This can improve fuel efficiency and also prolong the life of your engine.
