Signature Series: Oil Protects Turbochargers 72% Better than Required by GM DEXOS1 GEN2

Signature series oil protects turbochargers 72% better than required protection against the harmful deposits  common to turbocharges The General Motors Turbo cooking tests subjects motor oil to approximately 3 weeks of extreme heat soaks in the intense environment over turbocharged engine.

The turbocharger direct fuel injection combo has emerged as automakers favorite choice for producing powerful engines and meeting government fuel economy requirements. Increase airflow turbos generating enables an engine to burn more fuel and produce more power, this power comes at a cost. The tremendous heat stress turbos great cause oils to break down and form harmful bearing deposits through a process known as Turbo coking. Over time, turbos Consalvo reduce performance or fail altogether the Turbo coking test

The Turbo coking test was designed to stimulate the extreme operating conditions over turbocharged engine. Evaluates a mowing oils ability to resist deposit build up in the oil passages and brushing’s over turbocharger. Temperature increases within the Turbo and the weight of any deposits are recorded

Signature Series Protects Turbochargers

The GM Turbo coking test requires an oil to limit the temperature change within the turbocharger to 13% or less to pass the test. Signature series limited the temperature increase to only 3.6%, controlling heat improving it protects against deposits common to high temperature engine environments.


  • The deposits common to turbochargers can lead to:
  • Block oil passages, oil starvation and eventual failure
  • Reduced turbine speed resulting in lower boost pressures, reduced performance and poor efficiency
  • Oil breakdown and oil burning
  • Expensive Turbo rebuild or replacement

Protects turbochargers 72% better than required by GM dexos1 Gen 2

Our unique synthetic formulation is inherently stable to resist oxidation and neutralize acids. Signature Series Motor Oil provides outstanding protection against deposits common to high-temperature engine environments. The tremendous heat and stress turbos create can cause some oils to break down and form harmful bearing deposits through a process known as turbo coking. Over time, turbos can suffer reduced

Preserves Horsepower

The extreme durability of Signature Series Motor Oil ensures your engine runs stronger, for longer. We installed Signature Series 5W-30 Synthetic Motor Oil in a Ford* F-150 with a new 3.5L Ecoboost engine to test its ability to protect turbocharged direct-injection (TDGI) engines from torque and horsepower loss during extended drain intervals up to 25,000 miles. Power sweeps were done at the beginning and end of the test to evaluate horsepower and torque retention. As the graph shows, Signature Series helped maintain engine performance throughout the 100,000 mile test.
