Regularly change your engine oil according to the manufacturer's recommendations. This will help keep your engine running smoothly and efficiently.

Check your engine's air filter regularly and replace it if necessary. A clean air filter can improve the performance of your engine and save you money on fuel.

Keep an eye on your engine's coolant level and top it up if needed. This will prevent overheating and potential damage to your engine.

Invest in a quality fuel that contains cleaners and additives to help keep your engine clean and improve its overall performance.

Don't ignore warning signs such as strange noises or a decrease in performance. These could be indicators of a bigger issue with your engine.
