The fuel consumption may increase if an air filter is caught. Its condition should be periodically checked, particularly after having travelled more than 2,000 kilometres. This situation can occur if the air filter has been replaced by a non-quality, non-original. It may also be caused by bad oxygen (lambda-probes) and other malfunctions that are detected only by computer diagnostics. So if an air filter is in order, we should ask for help from specialists.
It is important to test the spark plugs (their wear can also affect the cost) and the tyre pressure.
