Frantz Bypass Oil Filters

The Ultimate Oil Filtration Solution

Extend Engine Life with Superior Oil Filtration

Frantz Bypass Oil Filters are engineered to deliver unmatched filtration performance, removing contaminants as small as 2 microns. This level of filtration helps significantly reduce engine wear, improves efficiency, and prolongs the life of your engine and oil—saving you time and money on costly oil changes and repairs.

How FRANTZ FILTERS Work

This simple to install, supplemental filter system removes solid contamination, like wear metals and dirt, from lubricating oil. The Frantz Filter Systems are capable of removing extremely small size particles from the oil by providing filtration through a densely packed filtering media. Oil flowing through the filter system is controlled at a deliberate rate, which allows for a constant source of clean oil.

What Makes Frantz Filters Different?

Unlike traditional full-flow oil filters that only catch larger particles, Frantz Bypass Filters continuously filter a small portion of your engine oil at a time with extreme precision. This high-efficiency method removes soot, dirt, and microscopic debris that standard filters often miss—making your engine run cleaner and last longer.

Trusted Since the 1950s

Frantz Filters have stood the test of time. Since the 1950s, drivers, mechanics, fleet managers, and engine enthusiasts have relied on Frantz for proven durability and long-term performance. With over 70 years of trusted use in the field, Frantz remains a leading name in oil filtration.

Save on Oil Changes

One of the biggest advantages of installing a Frantz Bypass Filter is the dramatic reduction in oil changes. By keeping your oil cleaner for longer, you can extend change intervals to 25,000 miles or more, depending on your driving habits and engine type. Fewer oil changes mean less expense and less environmental waste.
