Oil consumption depends on engine power output and fuel consumption. Your engine will consume more oil when you are driving a sportier car or faster or with a trailer to transport heavy objects. Whenever you find out that your vehicle is consuming more oil than before under the same conditions of use, you need to search why this is happening. High oil consumption can cause air pollution and can affect after-treatment devices such as particulate filters and catalysts. Some reasons for higher oil consumption are the following:
- Abnormal piston ring and cylinder wear.
- Defective crankcase ventilation.
- Worn valve seals.
- Abnormal turbocharger wear.
This list is indicative. There are many reasons why your oil consumption might be high. We recommend that you consult a qualified mechanic.
Please note that all these are mainly recommendations. You should follow the steps carefully and remember that you are responsible for these actions. So, be sure that you have both necessary equipment and skills. If not, we suggest that you should address to a qualified mechanic so as to implement these operations. We also recommend that you recycle your used oil by taking it to an oil change center or a waste recycling facility. Any type of oil can be reused: car oil, motorbike oil, truck oil, tractor oil, boat oil and others. In recycling, do not mix different products such as brake fluid, coolant and engine oil. Each fluid has to be recycled separately. Even small quantities of coolant or brake fluid in used engine oil could disrupt or halt the recycling process.
