AMSOIL Leads Others in Industry-Standard Testing

Signature Series 5W-30 Synthetic Motor Oil was tested against other oils to determine which provides the greatest level of protection against deposit formation in high-heat applications. The TEOST (Thermo-Oxidation Engine Oil Simulation Test) 33C test (ASTM D6335) is an industry-standard bench test that simulates turbocharger operating conditions.

AMSOIL Signature Series 5W-30 Synthetic Motor Oil protects against harmful deposits on turbochargers 4X better than Mobil 1 Extended Performance and 3.6X better than Royal Purple in industry-standard testing.*
Signature Series 5W-30 Synthetic Motor Oil was tested against both oils to determine which provides the greatest level of protection against deposit formation in high-heat applications.
The TEOST (Thermo-Oxidation Engine Oil Simulation Test) 33C test (ASTM D6335) is an industry-standard bench test that simulates turbocharger operating conditions. To meet the API SN Resource Conserving and ILSAC GF-5 motor oil specifications that are often recommended by vehicle manufacturers, a 5W-30 motor oil must limit total deposit formation to 30 mg or less.
AMSOIL Signature Series 5W-30 Synthetic Motor Oil held the total weight of deposits to 7 mg, well under the 30 mg limit required by the API and ILSAC, while Royal Purple API 5W-30 and Mobil 1 Extended Performance 5W-30 came in just under the limit at 25.4 mg and 28.2 mg, respectively.
“Turbochargers are becoming more prevalent because they play a critical role in helping vehicle manufacturers deliver the fuel economy the government mandates as well as the power and performance enthusiasts demand,” said AMSOIL Vice President, Technical Development Dan Peterson. “Demonstrating our protection capabilities in severe applications like turbo technologies backs up our commitment to car enthusiasts around the world.”
