1.What does a oil filter do?
The oil filter helps remove contaminants from your car engine's oil that can accumulate over time as the oil keeps your engine clean. Clean motor oil is important because if the oil were left unfiltered for a period of time, it could become saturated with tiny, hard particles that can wear surfaces in your engine.
- How often should oil filter be changed?
Get a new oil filter with every oil change. Most vehicles require an oil change every three to six months. Some manufacturers recommend replacing the filter with every other oil change, and doing so with each appointment prevents it from clogging prematurely.
3 Does brand of oil filter matter?"Filters are filters, it doesn't matter what kind of oil you're using," says Dennis Mott, automotive professor at Centennial College in Toronto. Filters are the kidneys of your engine, and they're not fussy – they'll screen debris out of any engine oil, whether that oil is conventional or synthetic, Mott says.
