KLEENOIL for Engines

Clean Oil, Longer Life, Cleaner Future

The KLEENOIL Bypass Filtration System is a powerful, proven solution for any size of engine—from commercial vehicles and marine fleets to power generation equipment. By continuously filtering engine oil during operation, KLEENOIL removes harmful contaminants and moisture, drastically extending oil life and protecting critical components.

Why Engine Filtration Matters More Than Ever

With tightening emissions regulations, modern diesel engines now use technologies such as Exhaust Gas Recirculation (EGR) and Selective Catalytic Reduction (SCR) to reduce Nitrogen Oxide (NOx) levels. While effective for emissions, these technologies introduce a new challenge: increased contamination of engine oil with soot, acids, and combustion by-products.

EGR systems recirculate a portion of exhaust gas back into the combustion chamber, reducing combustion temperatures but introducing corrosive gases and soot into the engine oil. This results in:

Simple, Effective, Proven

KLEENOIL brings engine oil cleanliness to a level that meets the challenges of modern engine design—without complexity or compromise. It’s a solution trusted across industries worldwide for one reason: it works.

Whether you manage heavy-duty vehicles, marine engines, or industrial generators, KLEENOIL delivers the protection, savings, and sustainability you need to stay ahead.

How KLEENOIL Protects Your Engine

KLEENOIL is a simple, effective installation that uses engine pressure to direct a partial flow of oil through a high-density cellulose depth filter. The filtered oil then continuously returns to the sump—clean, dry, and particle-free.

From the moment it’s installed, KLEENOIL maintains oil “as new”, requiring only periodic cartridge changes. With proper monitoring, annual oil and standard filter changes can replace frequent full drains—delivering exceptional cost and time savings.

Key Benefits of KLEENOIL Bypass Filtration

Eliminates Water

Water is always present in oil—but with KLEENOIL, it’s removed down to less than 0.05%, preventing sulfuric acid formation that accelerates engine wear.

Removes Dirt and Contaminants

Conventional filters typically remove particles down to, at very best 10 microns. KLEENOIL goes further, filtering down to 3 microns, dramatically reducing wear and preventing engine or pump failure.

Preserves Critical Additives

While removing contaminants, KLEENOIL retains key oil additives—including dispersants, anti-wear agents, detergents, and oxidation inhibitors—ensuring continued lubrication performance.

Extends Drain Intervals

With consistently clean, dry oil, you can extend drain intervals by up to 10 times.

On average, this means:
• 5x longer oil life for engines
• 10x longer oil life for hydraulics

Oil analysis confirms when the oil remains serviceable—keeping your fleet running longer, cleaner, and smarter.

Reduces Service Time

A KLEENOIL cartridge change takes less than 10 minutes, with no mess, no full fluid drain, and no waste oil to dispose of. It’s a fast, safe, and clean alternative to conventional maintenance.

Provides Continuous Protection

KLEENOIL filters whenever there’s oil pressure. Each filter is densely wound with natural coniferous long-fibre cellulose, capturing particles, absorbing moisture, and allowing only clean oil to return. The result is a closed-loop filtration cycle that operates continuously in the background.

Environmentally Responsible

Oil is a finite resource. Every litre you preserve with KLEENOIL reduces environmental impact. By avoiding frequent oil changes:

• You reduce oil consumption and purchasing costs • You minimise waste disposal • You lower the risk of oil spills and ground contamination

Fewer oil changes mean fewer chances of environmental harm—making KLEENOIL not just a cost-saving tool, but a sustainability solution.
