When your engine sounds off or acceleration feels weak, اتوسرویس داوود it might not be a sign of major mechanical failure—it could be as simple as a dirty filter. The lubrication filter plays a critical role in keeping your engine clean by trapping dirt, metal shavings, and other contaminants that circulate with the motor oil. Over time, the filter becomes saturated and loses its effectiveness. Here are some signs that your car may need a fresh filtration unit.

A primary warning sign is a reduced power output. If you notice your car lagging when you try to speed up or struggling to maintain speed, it could mean the oil isn’t flowing properly due to a clogged media. This forces the engine to overexert itself and can lead to increased wear on internal components.

Another red flag is the check engine light coming on. While this warning can mean numerous potential problems, a old, ineffective filter can trigger it by causing inadequate hydraulic pressure. The vehicle’s sensors detect that oil isn’t reaching critical parts at the right rate and activate the warning system as a precaution.

You might also hear odd rattling or knocking coming from under the hood. A metallic clinking, especially when the engine is at rest, can signal that the oil isn’t coating moving components. This often happens when the filter is severely blocked to allow proper circulation.

Black, gritty fluid is another clue. If you check your oil dipstick and the oil looks dark and sludgy instead of a clean, translucent tone, it may mean the filter is worn out. A properly functioning filter keeps the oil pure and stable for longer, so if the oil gets dirty far sooner than expected, the filter might be the culprit.

If you’ve skipped filter changes, the filter may be past its useful life. Most manufacturers suggest changing the filter with every oil service. Skipping this step can cause the old filter to impede circulation or even release accumulated contaminants.

Neglecting these symptoms can lead to serious engine damage. Replacing the oil filter is a quick, low-cost procedure that can save you from major breakdowns later. When in doubt, check the manufacturer’s recommendations or seek professional advice to ensure your engine stays well-lubricated.
