Yes. A clogged oil filter can trigger the bypass valve, letting unfiltered oil circulate in the engine, which increases metal-to-metal wear and engine sludge formation. While most workshops in Pakistan replace the oil filter with each oil change, some use cheap aftermarket filters that may clog early o r even collapse internally. Always insist on genuine o r OEM-grade oil filters.
