Where is the oil filter located on the Focus?
2 Answers
The oil filter on the Focus is located underneath the engine, and you'll need to lift the car with a hoist to see it. Every engine has an oil filter, which serves to filter the oil, keeping it clean. Without an oil filter, the oil would become very dirty after some use, affecting the engine's operation and lubrication. The oil filter, also known as the oil cleaner, functions to remove debris, gum, and moisture from the oil, delivering clean oil to the various lubrication points. The dimensions of the Focus are 4647mm in length, 1810mm in width, and 1468mm in height, with a wheelbase of 2705mm.
The oil filter location for the Focus is generally on the lower right front side of the engine. In most cases, you'll need to lift the car or crawl under the chassis to see it, typically near the oil pan where it connects to the engine block. I've changed it myself several times—it's usually on the right side corresponding to the driver's compartment, closer to the inner side of the front wheel. There might be slight variations depending on the model year. Pre-2012 older models might be easier to locate, while newer models like those after 2018 sometimes hide behind other components, adding a bit of difficulty. Before inspection or replacement, it's advisable to check the user manual or search online for diagrams specific to your model to avoid damaging other parts. If you're doing it yourself, prepare the right wrench set, a new filter, and an oil drain pan. Remember not to overtighten the new filter after draining the oil to avoid damaging the threads, and always replace the oil at the same time for a complete job—otherwise, a clogged filter can accelerate engine wear and reduce mileage. Developing a habit of checking every 5,000 km and regular replacement can significantly extend engine life and ensure stable lubrication system performance.
