MBL8 Concentrated Oil Additive is an outstanding oil supplement for petrol and diesel engines, which has been designed to increase horsepower and fuel economy, restore compression, reduce emissions, oil consumption, engine and gear wear. MBL8 Concentrated Oil Additive consists of micro-metallic particles suspended in a base oil, together with other ingredients which provide superior lubrication, reducing friction, heat and wear. For use in petrol and diesel engines, manual transmissions, differentials (not limited slip differentials), transfer cases, power steering, some air compressors and hydraulic systems.

Action and Benefits

There are three basic mechanisms of action.

1. Lubricating Action - The product contains micrometallic particles.
2. Filling Action - MBL8 fills in minor grooves, scratches and pits,.
3. Plating Action - MBL8 plates into the surface, repairing the scarred or worn area. 

Regular use of MBL8 Concentrated Oil Additive can:

  • Decrease fuel consumption.
  • Decrease oil consumption.
  • Decrease smoking.
  • Restore compression.
  • Increase horsepower.
  • Reduce emissions.
  • Repair by plating into minor scratches and surface imperfections.
  • Extend component life.
  • Reduce Friction.
  • Micro-metallic particles
  • An Anti Friction ingredient
  • A Particle Suspension agent
  • An Anti-Corrosion agent
  • An Anti-Foam agent
  • An Anti-Oxidant
  • A Dispersant


Allow 5000km or 100hours of operation to a new or reconditioned engine before adding MBL8 Concentrate Oil Additive, to permit initial break-in.

Add immediately in all other applications.

  • MBL8 is specifically designed for enhanced lubrication where the use of normal lubricating oils is specified. In situations where limited lubrication is required, such as in automatic transmissions, the use of MBL8 should be avoided.
  • MBL8 contains particulate materials which possess particle sizes in the 1 to 10 micron range. In applications where these particle ranges may produce mechanical problems or be screened out, the use of MBL8 should be avoided.
  • MBL8 should not be used in limited slip differentials automatic transmissions, wet clutch or wet brake applications.
  • MBL8 should not be used in ammonia compressors or in the presence of any acidic or caustic medium.

MBL8 must be shaken vigorously before using. For best results, MBL8 should be added during an oil and filter change. After draining oil and replacing filter, add the specified amount of oil less 1 litre (more for larger applications).

Mix MBL8 thoroughly with the last litre of oil. Add to the engine and operate immediately for at least 15 to 30 minutes before shutdown. With components, i.e., manual gearboxes, differentials, etc., always ensure that MBL8 is thoroughly mixed with oil before adding to the component being treated. Always mix MBL8 with oil before treating any component.

Recommended Dosages in Petrol or Diesel Engines

Passenger cars and light commercial vehicles:
(a) With 4 cylinders, add 75mL per application.
(b) With 6 cylinders, add 100mL per application.
(c) With 8 cylinders, add 125mL per application.

Heavy trucks, industrial, marine and commercial applications:
With 6 or 8 cylinders, add 250mL per application.

Large industrial and marine application:
20mL per litre of engine oil.

Future Oil Changes: Continue the recommended oil change schedule after the first application of MBL8 adding the proper dosage listed above with each oil change.

In manual transmissions, differentials and gearboxes add 20 mL of MBL8 per litre of oil (Not for use in automatic transmissions or Limited Slip Differentials).

Do NOT use in torque converter systems or with clutches or brakes that operate in oil.

For small engines such as 4 stroke mowers and industrial engines add 20 mL per litre or 1 part MBL8 to 50 parts engine oil.
