 A superior oil filter performing efficiently |
 A Poor Performing Oil Filter |
||
| Efficiency | Prevents damage to the engine's bottom end, including bearings and crankshaft. | Poor efficiency = high engine wear. | |
| Life | Long life = engine protected for the entire service interval. | Short life = high engine wear. | |
| Flow | Improved flow = reduced risk of oil starvation enhancing engine protection. | High filter restriction starves the engine of oil flow at low RPM = rapid bearing wear. |
