Why Your Diesel Needs an Oil Bypass System
Factory oil filtration systems typically only filter down to 20-40 microns, allowing harmful particles to circulate through your engine. Our bypass system:
- Diverts a portion of oil through an ultra-fine 2 micron filter
- Gradually cleans the entire oil supply over multiple cycles
- Protects bearings, turbochargers, and other critical components
- Extends oil change intervals by maintaining cleaner oil
