· ASTM D6335 | Dual/33C Model
(Chinese SH/T0750)

· ASTM D7097 | MHT® Model
(Moderately High Temperature)

· ASTM D8447 | TEOST Turbo®


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 with MHT™ and Turbo™ tests for easy viewing of depositor area during the test.

Ability to collect the volatilized material for further analysis and investigation.
