Oil consumption is determined by engine power and fuel consumption. This means that your engine will consume more oil when you drive a sports car or a car with a trailer to transport horses or boats. Whenever your car has consumed more oil than usual, under the same conditions of use, you should understand why this happens. High oil consumption can create air pollution and can affect the vehicle, such as the particulate filter and the catalytic converter. Below are some of the reasons for higher oil consumption:
- Abnormal piston ring and cylinder wear.
- Defective crankcase ventilation.
- Worn valve seals.
- Abnormal turbocharger wear.
This list is not exhaustive. There are plenty of reasons why your oil consumption may be high. We recommend that you see a qualified mechanic.
