Tested product

MATHY® UNIVERSAL-M

Testing institute

Hamburg University of Technology Institute of Product Development and Design Engineering

Conclusion

The additive has a strong influence on the lubricity and anti-wear properties of the oils.

The addition of MATHY® UNIVERSAL-M to engine oils leads to

• a significant reduction in the mean coefficient of friction.
• a significant reduction in the volume of wear.

a lowering of the critical high pressure PHD,krit (critical Hertzian pressure pHertz,krit).

Test procedure - Designation

The MPH test procedure (mechanical testing of hydraulic fluids) at the Hamburg University of Technology is a new test procedure for testing the lubricity of hydraulic fluids.

Testverfahren – Ziel

To obtain a statement on the effectiveness of the MATHY® UNIVERSAL-M additive added to the engine oil in terms of lubricity and wear protection.

Testverfahren – Beschreibung

The testing device for mechanical testing (MPH test method) of hydraulic fluids, transmission and engine oils is suitable for mapping the tribological situations that occur in machines. At the same time, it is designed so simply that it can work with test specimens of simple geometry.
