Thermo-Oxidation Engine Oil Simulation Test

The TEOST 33C test simulates the effect of engine operating conditions on the oxidation and deposit-forming tendencies of engine oils, especially in the high-temperature Turbocharger area. The TEOST MHT^® test simulates similar effects and conditions found in the ring belt and piston ring areas of the engine.

Oil samples treated with catalysts are pumped over a heated 33C Depositor Rod or a coiled MHT^® Depositor Rod on which deposits form. 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.

• Adjustable temperature zones and pump speeds.
• Clear Glass Mantle for easy viewing of depositor area during the test.
• Ability to collect the volatilized material for further analysis and investigation.
