Thermo-Oxidation Engine Oil Simulation Test

The TEOST® is a valuable tool for researchers, engineers, and quality control professionals seeking to understand and improve the performance of engine oils. It is a bench-top instrument designed to simulate engine operating conditions and assess the deposition tendencies of engine oils. It offers two primary testing protocols:

 

TEOST® 33C (ASTM D6335)

Simulates turbocharger operating conditions, including cyclic temperatures of 200-500°C. Measures oil deposition on a resistively-heated rod over a 12-cycle, 2-hour test. Used in ILSAC GF-2, API SJ, and Daimler/Chrysler OEM specifications.

 

TEOST® MHT (ASTM D7097)

Simulates high-temperature conditions (250-300°C) in the piston ring belt area.
Measures oil deposition on a steel rod over a 24-hour test.
Used in ILSAC GF-3, GF-4, API SL, and SM categories.
