How do I properly maintain my Toyota Hilux's diesel engine?

I just bought a Toyota Hilux with a diesel engine, and I want to make sure I take good care of it to ensure its longevity. What steps should I take to properly maintain my diesel engine? Any specific products or techniques I should use?

Regular oil changes are crucial for keeping your diesel engine in good condition. Make sure to use high-quality diesel engine oil that is specifically recommended for Toyota vehicles.

Keeping your fuel filter clean is also important for diesel engines. I recommend investing in a good quality fuel filter and checking it regularly to make sure it's not clogged.

Another important aspect of diesel engine maintenance is keeping the air filter clean. I suggest checking and replacing it at least every 30,000 miles or more often if you drive in dusty or dirty environments.

Regularly checking and maintaining your battery is crucial for diesel engines. Make sure to clean any corrosion and check the electrolyte levels to ensure your battery is in good condition.

Lastly, I highly recommend using a diesel engine additive to improve fuel efficiency, reduce emissions and prevent engine wear. Make sure to choose one that is compatible with your Toyota Hilux.
