The illustration above demonstrates what happens if oil is reclaimed properly at regular intervals. Purification is not a workable solution once an oil has severely degraded — but used properly on a preventive maintenance schedule, purification offers tremendous benefits.

As additive levels gradually drop due to consumption, a very small amount of oxidation will take place. But rather than allowing the oil to degrade to a point where it becomes unusable and unsalvageable, it can be purified and reclaimed, and the additives can be restored to their original levels.

The fresh additives begin the next “life cycle” of the oil, and the same scenario can take place again and again and again: a very small amount of oxidation occurs, the oil is purified and reclaimed, and the additives are restored.

The net effect is that oxidation is controlled at very low levels, water and contaminants never build up to troublesome levels, and oil life can be extended continuously.
