If you skip changing this filter, you risk expensive car engine failures
The question of how long an oil filter lasts may sound unusual, as it is customary to change it every time the engine oil is changed. Filters are not expensive and provide important and affordable protection against potentially very expensive engine failures. Although drivers often pay the most attention to the choice of brand and type of engine oil, it should not be forgotten that the filter itself plays a key role in keeping the oil clean, so it is equally important to pay attention to its quality and type.
TL;DR
- Oil filters are inexpensive but vital for preventing costly engine damage.
- There are two main types: cellulose (standard, needs replacement by 8,000 km) and synthetic (lasts 10,000 miles or more).
- A clogged filter can restrict oil pressure, causing unfiltered, dirty oil to circulate, leading to engine damage.
- It is best to replace the oil filter every time the engine oil is changed for optimal engine health.
- Replacing both oil and filter simultaneously is the best option for engine longevity and cost-effectiveness.
