Unlike a gasoline engine, a diesel engine must be at the right temperature to operate properly , hence the importance of properly preheating the engine (about 1 minute): you have to wait for the warning light to go out before starting. Running the engine allows the oil to reach all the engine parts to lubricate them well, especially the turbocharger.
Why is cold starting difficult on a diesel? To self-ignite, diesel needs to be hot. This is the role of the glow plugs, by increasing the temperature in the combustion chamber.
Nervous driving and a diesel engine don’t mix: driving a diesel means adopting a smooth, smooth ride, without pushing the engine to too high speeds or over-revving . These precautions make it possible to reduce consumption and not to wear out the engine prematurely.
Choosing a diesel fuel with additive optimizes performance:
On a diesel vehicle, it is also advisable to refuel as soon as the diesel tank gauge reaches 50% (the less diesel there is, the more the particles at the bottom of the tank will be concentrated, which then risks clogging the fuel system). ‘injection).
This is all the more true since a diesel engine does not like water : if your tank is partly empty, there is a risk of condensation, especially in summer. The water present will be proportionally all the more important as there is little diesel, which can lead to corrosion of the car injector or the pump.
Diesel car overhaul and oil change: when should it be done?
Engine oil has the essential function of lubricating the various mechanical parts of an engine: it helps to evacuate dirt (impurities, metal particles, etc.) then blocked by the oil filter, while preventing corrosion of these parts by the water.
The purpose of draining a diesel engine is to change the used oil, which no longer performs these functions correctly: it is an essential operation in the maintenance of a car and it is always accompanied by changing the filter. oil. When the maintenance also includes checking other elements (check points) or changing other wearing parts (diesel fuel filter, air filter, etc.), this is called an overhaul . The frequency and intensity of overhauls are set by the maintenance log.
Every 6 months or every 7,500 km , an engine oil change must be done (used oil changed and oil filter replaced) on older models.
For a recent diesel, this frequency is sometimes 20,000 or even 30,000 km . Consult our article on maintenance and overhaul for the petrol car .

Every 40,000 km , the glow plugs must be replaced. Please note that these are indications: you must strictly follow the advice in the maintenance booklet.
