How does a dirty oil filter affect engine oil flow?
This means that the amount of oil reaching engine internals is NOT influenced by how dirty the filter is. Only the “effort” made by the pump to push oil thru it changes (and a bypass valve saves engine and pump in case of excess pressure) so you know that your engine will be having the oil flow it need.
What is an oil filter and how does it work?
