The gasoline filter of this car is located on the firewall behind the engine compartment. Introduction to the oil filter: The oil filter is a component that filters the engine oil. Engine oil contains a certain amount of gum, impurities, water, and additives; during engine operation, metal shavings generated by friction between parts, impurities from the intake air, and oxides in the oil are all filtered by the oil filter. If the oil is not filtered and directly enters the oil circuit, it will adversely affect the engine's performance and lifespan. Removal of the oil filter: Open the engine hood, unscrew the oil cap, locate the oil pan, find the nut on the oil pan, loosen it with a wrench, and place a waste oil bucket underneath to catch the black waste oil. Once the waste oil has completely drained, use a specialized tool to remove the oil filter.

To be honest, as someone who frequently performs DIY car maintenance, I think the fuel filter of the Volvo S90 is most likely hidden inside the fuel tank. Most modern cars are designed this way, mainly to prevent dust and contaminants from entering the engine. You'll need to lift the rear seat cushion or trunk floor to access the fuel tank cover, as it's usually integrated with the fuel pump. Replacing it is a bit troublesome, but checking it every 20,000 kilometers can prevent engine shaking or starting issues. Remember, don't operate in dusty environments, and make sure the engine has cooled down before starting—safety first. Last time I changed it, I saved a few hundred dollars in labor costs, but if you're not familiar with the process, it's better to go to a professional shop. After all, the S90 is a premium car, and you don't want to risk damaging it.

Speaking from my experience as a novice car owner, the gasoline filter of the Volvo S90 is most likely located under the chassis or inside the fuel tank. The exact position depends on the model year. Newer models often have it built into the fuel tank, requiring the fuel pump module to be disassembled for access, while older models may have it externally mounted near the rear wheels under the chassis. Its function is to filter impurities from the gasoline, preventing clogging of the fuel injectors. I recommend checking it every 15,000 to 20,000 kilometers; otherwise, fuel efficiency will drop, and the car will feel sluggish. If the car has difficulty starting or experiences jerky acceleration, the filter might be clogged. If you plan to replace it yourself, prepare gloves and tools, but since the S90 has a low chassis, it's best to use a jack to lift the car for the operation to avoid scratching the paint.

I've been driving the S90 for several years. The fuel filter is usually located inside the fuel tank and connected to the fuel pump, which provides maximum protection for the engine. Replacing it isn't too complicated, but requires some patience—you need to drain the fuel from the tank and remove the cover to access the filter component. Why is it designed this way? To minimize the risk of external contamination. Don't forget, regular maintenance of this part can improve fuel efficiency. I replace mine every 20,000 kilometers, and it takes about half an hour to complete.
