Yes, a standard oil change always includes changing the oil filter.
Why Change the Oil Filter?
The oil filter is a crucial component of your engine's lubrication system. It traps contaminants like dirt, metal particles, and other debris that circulate in the engine oil. Leaving the old, clogged filter in place during an oil change defeats the purpose of the fresh oil. The new oil would immediately become contaminated, negating the benefits of the oil change.
Several sources confirm this practice:
- Multiple online forums and articles (Reddit, BobIsTheOilGuy, Quora, etc.) consistently emphasize the importance of replacing the oil filter with every oil change. These sources highlight that failing to do so compromises engine health and longevity.
- Automotive service providers and reputable websites such as 66Nissan, generally include oil filter replacement as a standard part of their oil change service.
In short: A complete oil change involves replacing both the old oil and the old oil filter with new ones. This ensures optimal engine performance and protection.
Exceptions:
While rare, there might be very unusual circumstances where an oil filter might not be changed during an oil change. However, this is strongly discouraged and not a standard practice.
- A mechanic might, in a very rare emergency situation, choose to only change the oil to get a vehicle running temporarily. However, this is not a recommended long-term solution and the filter must be replaced as soon as possible.
