If you have a diesel car then there may be a few additional things you need to do to look after it.

All diesel cars have been designed to be used when you do a fair few miles. Diesel vehicles that have been built since 2009 must by law have a diesel particulate filter fitted to them. This filter helps to stop harmful substances from being released into the atmosphere. Instead, the engine has to get hot enough to burn up the soot that the diesel particulate filter has collected up and turn it in to ash.

If you have not done a long journey for a while you need to ensure that you take it on a good run. The regeneration process can only work if the engine is at a certain temperature so this usually requires you to run the car for around 25-30 mins at high revs.

Another thing to look out for with diesels is the injectors. To prolong them you should try and use quality fuel. The worse the quality of the fuel, the more negative impact it will have on the injectors; they are prone to damage and expensive to replace and remember you have four of them so this can very quickly add up.
