Diesel engine maintenance tips.

Diesel powered engines are popular for many reasons, including their durability, power and fuel efficiency.

The way you use, and care for, a diesel engine will have an impact on these perceived benefits. If you want to achieve optimum performance, there are some simple maintenance checks that you can do yourself, at home, to keep your diesel powered vehicle in good working condition.

Keep the engine clean.

A dirty diesel engine may experience a shortened lifespan and experience a decrease in fuel efficiency and performance.
When compared to a petrol engine, diesel engines produce more oil contaminants and place greater pressure on the internal filtration system. As a result, it is essential that you adhere to the scheduled servicing as outlined in your owner’s manual.
Keep dirt and grime to a minimum, but be sure to first consult with your owner’s manual before you carry out any cleaning. This will avoid unnecessary damage to the vehicle and yourself. Always ensure that the engine is cool first, wear protective clothing and when in doubt, speak to the trusted professionals at your local BestDrive store to discuss how we can help to keep your diesel engine performing at its best.

Check your air filter.

A new, or clean, air filter will assist in the performance of your diesel engine. How often you need to replace your vehicle’s air filter will be partially dependent on the climate and environment that you typically drive in.
A dirty air filter restricts the flow of air to your engine and can add unnecessary strain to your engine. This can cause the engine to use more fuel as it needs to work harder to get the necessary power and acceleration that you require.
You can easily assess the condition of your air filter when performing simple car maintenance at home. Your owner’s manual will specify when the air filter requires changing, but if you are unsure, you can contact your local BestDrive store for advice you can trust.

Maintain your engine’s radiator.

Diesel engines typically run hotter than petrol engines, which means that their radiators are subject to higher temperatures. This can lead to overheating. Coolant prevents the engine from overheating and prevents corrosion damage, which is why it’s essential that you maintain your engine coolant levels.
You should check your engine coolant twice a year. It is always a good idea to refer back to your owner’s manual to check the manufacturer’s recommendations for your diesel vehicle. If you notice that your coolant levels are dropping and you aren’t sure why, call into your local BestDrive store where the issue can be identified and rectified by a professional.

Replace your fuel filters.

Your fuel filters should be replaced as recommended by your vehicle manufacturer. Typically, this is around every 16,000 to 24,000 kilometres. This information can be found in your owner’s manual.
Most modern diesel engines have two fuel filters, a primary and a secondary, which should be replaced at the same time for optimal efficiency and lifespan.
