Why does the Frantz Oil Filter work so well?
Consider the standard full-flow filter from your car manufacturer. It usually consists of a piece of paper or cardboard curved into a circle and is usually corrugated for strength – not for filtering! Then it is placed in a metal housing with a by-pass feature many are unaware of. It is not unlike your coffee filter whereby your coffee water flows through a thin membrane trapping coffee grounds (not always). The coffee filter is VERY thin and porous. The by-pass feature is a safeguard by your manufacturer to allow unfiltered oil to pass through the filter allowing dirty oil to be circulated in your engine.
