Tannas Thermo-oxidation Engine Oil Simulation Test

Principle

  • Moderately High Temperature test that simulates the effect of engine operating conditions on the oxidation and deposit-forming tendencies of engine oils, especially in the ring belt and piston ring areas of the engine.

  • Oil sample treated with catalyst is pumped over a heated coiled Depositor Rod forming ssociated deposits. The weight of the Depositor Rod after the test is subtracted from its pre-test weight and added to the particulate weight collected by filtering the oil remaining. The results are reported in milligrams.
