Can I replace the oil filter every other oil change?

You technically can, but it's not a great idea. Most mechanics in the UK recommend changing the oil filter every time you change your oil. It keeps the engine cleaner and running better.

In theory, it is possible to replace the oil filter every two oil changes, but it is recommended to replace the oil filter with every oil change.

Replacing the filter every other change is not ideal for the vehicle. After driving a certain mileage, the oil filter accumulates many impurities. If new oil is added without replacing the filter, the new oil can easily become contaminated. Therefore, it is best to replace the oil filter with every oil change. Additionally, in most cases, the oil filter should be replaced every 5,000 kilometers. However, vehicles using high-quality, long-life oil may extend this interval to 8,000–10,000 kilometers or more.

Steps to replace the oil filter:

1. Remove the drain plug and drain the engine oil completely. Wipe the drain plug clean and reinstall it.
2. Loosen the oil filter using an oil filter wrench, then apply engine oil to the O-ring of the new oil filter.
3. Hand-tighten the new oil filter onto the filter mount until the O-ring contacts the mounting surface. Finally, use the wrench to tighten the filter an additional three-quarters of a turn.
