Less fuel-intensive, Diesel engines however require more maintenance than their gasoline counterparts. Discover the mistakes to avoid to preserve your Diesel engine.
Just ten years ago, the Diesel was in top form, and had a lot of supporters, whether they were heavy rollers or not. The Dieselgate has been there, and even if it is criticized today, the Diesel engine remains renowned for being more torquey and less fuel-intensive. On the other hand, it requires regular maintenance in order to preserve it and reduce its clogging.
Mistake # 1: neglecting maintenance
More fragile, diesel engines require a scrupulous maintenance to ensure their longevity. As with any engine, oil change is an essential operation which must be carried out on a regular basis: it is recommended to do it every 15,000 km, in order to replace the used oil which gradually loses its lubricating properties. The opportunity also to replace the various filters: air, oil and diesel, to give it a second youth.
Mistake # 2: Using poor quality fuel
If it is tempting to opt for the cheapest fuel possible, to preserve your engine in the long term, it is recommended to use a premium diesel. The price difference is justified by the presence of fuel additives, which have detergent effects and act against corrosion and oxidation on the most sensitive parts of the engine, such as the injectors. To do the big cleaning, the additives to pour yourself into your fuel tank, also called engine cleaners, are not necessarily the ideal solution: prefer descaling at a professional for deep and risk-free cleaning.
Mistake # 3: Driving Brutally
To take care of your engine in the long term, it is first of all recommended to respect the heating time of your mechanics: wait for the engine to heat up, with an optimal temperature around 90 °, before going up in the towers . Drive your diesel engine smoothly, favoring eco-driving over its optimum operating range, and avoid driving under revs.
Mistake n ° 4: choosing a Diesel for urban use
The city is surely the enemy n ° 1 of Diesel: used at low speed and on short journeys, the engine and its components: turbo, EGR valve, particulate filter and injectors, clog up and eventually show signs of weakness. Do not hesitate to take your Diesel car out of town at least once a week, driving on the motorway in order to “clean” your mechanics, and to trigger a DPF regeneration cycle if your model has one.
