Frequency of engine oil change
Since 1996, all Fiesta engines have required oil changes every 15,000 km. However, if you drive long distances, you do not need to adhere to this interval exactly to the kilometre. If the car is used exclusively in the city or on short distances, it is recommended to change the oil once every 6 months. The replacement period is spring and autumn, since the fuel condensate that forms in winter must be removed from the engine before the onset of warm weather.
Changing oil yourself
Changing the oil yourself makes sense if you can buy quality oil at a low price. In any case, make sure that the oil meets the required specifications. During a regular oil change (drain the oil from the oil pan, replace the filter and dispose of the oil), you must lift the car. Compared to changing the oil yourself at a service station, the oil is pumped out with a special unit and, thus, the problem of disposing of the used oil is eliminated. However, this method has its drawbacks, as deposits remain in the oil pan.
Based on experience, changing engine oil at a service station is expensive, as they usually only have expensive types of oil. Some service stations additionally include oil filter replacement in the oil change work.
The volume of oil required for replacement in the Fiesta engine is given in Table 5.1.
15,000 km, 12 months
SEQUENCE OF WORKS
1. Warm up the engine to keep dirt particles in suspension.
2. Secure the vehicle to supports or place it on an overpass.
3. Place a suitable container under the oil pan.

4. Using a spanner, loosen the plug and drain the oil (Fig. 5.4). Be careful, as the oil is hot. Use only a drain plug with a new gasket.

5. Place a collecting container under the oil filter. Use a strap wrench to unscrew the oil filter (Fig. 5.5). If the filter does not unscrew, use a screwdriver to pierce the filter housing and, using the screwdriver as a lever, unscrew the filter. Pour the oil from the filter into the collecting container and dispose of it as special waste.
6. Apply a thin layer of fresh engine oil to the sealing ring of the new oil filter. Screw the filter in by hand.
7. Fill the engine with fresh oil. Run the engine briefly. The low oil pressure warning light will go out only when the new oil filter is filled with oil.
8. Check the tightness of the oil filter and engine oil drain. Lower the car.
PRACTICAL TIPS
Disposal of used motor oil
To protect the environment, it is necessary to eliminate the consequences of waste oil being absorbed into the soil. If the oil is changed at a service station, it is then recycled.
Old waste oil is collected by specialized companies and taken away for further processing. Therefore, it is not recommended to mix old oil with other liquids.
Engine oil leaks
If you see oil stains under the hood of your Fiesta, this is not a reason to worry. With strong temperature fluctuations, engine oil can find its way out through the pores of the engine gaskets. But if you notice large oil leaks in the engine compartment or oil stains in the parking lot, then you need to immediately find the cause of such an "oil source" and eliminate it as quickly as possible. It is best to take a test drive after washing and check your engine for oil leaks.
