When should you change your car's oil?

A car's engine differs from one brand to the next. In some circumstances, the driving conditions play a significant role in determining when you should change your car's engine oil. The engine is put under a lot of stress due to traffic, stop-and-go, potholes, and other factors.

Most engine oil specialists agree that changing your car's oil between 7,500 and 10,000 kilometres is the correct time. If you're using a mineral-based lubricant, stick to the 5,000–5,500 kilometre range.

Which engine oil performs better in terms of high mileage or fuel efficiency?

Many people dismiss the concept of high-mileage motor oil and dismiss it as a marketing gimmick. A high mileage synthetic engine oil usually contains additives and synthetic engine oil that ensure that the engine's longevity is preserved.

A high mileage engine oil contains detergents that clear out the crud and sludge that builds up inside the engine as a result of the engine's extended use. After 75,000 kilometres, it is normally advisable to upgrade to a high mileage engine oil. Anything prior to that may not be more useful than regular oil.

Do you think it's a good idea to blend mineral and synthetic engine oils?

In this case, the answer is yes.
