Will Sand Entering the Engine Be Filtered by the Oil Filter?
2 Answers
If the air filter is of qualified quality and clean, it can generally filter out fine particles and floating dust, preventing them from entering the engine. Detailed Introduction of the Oil Filter: The oil filter is designed to remove impurities, gum, and moisture from the engine oil, delivering clean oil to all lubrication points. Method for Replacing the Filter: Under normal usage, the filter should be replaced when the pre-filter's differential pressure alarm is triggered or after 300 hours of cumulative use. The dual-canister parallel pre-filter system allows for filter replacement without shutting down the engine.
Oh, this is a pretty common question. I think it can be explained in a few points. The function of the oil filter is to filter out impurities in the engine oil, and sand can indeed be filtered out because the material of the filter is very fine, like a mesh, which can block sand and dust. However, oil filters also have limitations. If the sand particles are too large or too numerous, they may pass through the filter and enter the engine, causing wear on the components. When I used to drive an off-road vehicle through sandy terrain, I always made a habit of checking the filter afterward. If I found sand or mud residue, I would immediately change the oil and filter. To avoid such issues, I recommend avoiding sandy or dusty roads when driving. If you must drive through sandy areas, don’t turn off the engine immediately after stopping—let the oil circulate a bit longer to carry away the sand and dust. Additionally, regular maintenance is key. Follow the manufacturer’s recommended intervals for oil and filter changes to significantly reduce risks. The engine is the heart of the car—protecting it extends the vehicle’s lifespan and avoids major repairs. In short, the filter can filter out sand, but you shouldn’t rely on it entirely. Combine it with preventive measures.
