The lubricating gaps in the engine have a size of approx. 2 to >10 µm, the usual standard oil filters have only a filter capacity of up to approx. 20 µm at best. Oil is a mineral and does not age, but a process of change is caused by dirt and abrasion particles, combustion residues (soot), oxidation products and water (by condensation) in the engine.

Standard filtering is not sufficient, as only particles with a size of 20-35 µm are filtered. During an oil change, some of the contaminated oil remains in the engine. The number of dirt and abrasion particles is constantly increasing and the engine runs continuously with contaminated oil and solid particles. This causes further abrasion.

Standard filters are not able to filter out condensed water and prevent acid formation. This leads to a reduction in TBNs and an increased oxidation.

The micfil ultra fine filter has a filter performance approx. 20 times higher than a standard filter. Dirt, combustion, oxidation and abrasion particles of up to 0.5 µm are constantly filtered out of the oil. Particles of less than 1 µm remain in the oil. They do not cause any damage and accumulate in the oil which contributes to additives for better lubrication. This significantly increases the load-carrying capacity (lubricity) compared to fresh oil and the thermal load capacity of the oil. These properties become better the longer the oil is used.

An oil change is therefore not always necessary for technically good engines. The micfil ultra-fine filter acts like an oil recycling system on the engine. Nevertheless, other causes, e.g. overheating, material defects, etc., can cause damage to the engine. The technical condition of the engine should therefore be checked regularly by oil analyses prior to oil changes.

Removing the smallest particles is the key to prolonging engine life!!
