Signature Series Protects Turbochargers
The turbocharger/direct fuel injection combo has emerged as automakers’ favored choice for producing powerful engines and meeting government fuel-economy requirements. The increased airflow turbos generate enables an engine to burn more fuel and produce more power, but this power comes at a cost. The tremendous heat and stress turbos create cause some oils to break down and form harmful bearing deposits through a process known as turbo coking. Over time, turbos can suffer reduced performance or fail altogether.
How Turbos Could Slow You Down
The deposits common to turbochargers can lead to:
- Blocked 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
The GM Turbo Coking Test
The Turbo Coking Test was designed to simulate the extreme operating conditions of a turbocharged engine. It evaluates a motor oil’s ability to resist deposit buildup in the oil passages and bushings of a turbocharger. Temperature increases within the turbo and the weight of any deposits are recorded.
Test Parameters
Engine 2012 GM 1.4L
Duration 2,000 cycles of extreme heat soaks – approximately 537 hours
Measures A motor oil’s ability to resist deposits in a turbocharger’s oil passages and bushings
Simulates High-heat operation of a turbocharged engine
Requirement Temperature change within the turbocharger limited to 13 percent
Signature Series protects turbochargers 72% better than required by GM dexos1® Gen 21
The GM Turbo Coking Test requires an oil to limit the temperature change within the turbocharger to 13 percent or less to pass the test. Signature Series limited the temperature increase to only 3.6 percent, controlling heat and proving it protects against deposits common to high-temperature engine environments.

Another Win for AMSOIL Products
A HOT ROD magazine dyno test proves that AMSOIL synthetic lubricants increase power, torque and fuel economy.
Another Win for AMSOIL Synthetic Lubricants
The advantages of synthetic lubricants are well established. The fact that most motor oil companies today offer a full-synthetic oil is evidence of what AMSOIL has long known: synthetic lubricants deliver the long-term protection and performance auto enthusiasts desire better than conventional oils.
Recently, our friends at HOT ROD magazine conducted a test that provided dramatic confirmation. They requested a variety of AMSOIL products to test in a 2006 5.7L Dodge* Charger*. The testing was done at the Pennsylvania College of Technology’s dyno laboratory. The Charger (previously run solely on conventional oil) was installed with these AMSOIL products:
- Signature Series 5W-20 Synthetic Motor Oil
- Signature Series Multi-Vehicle Synthetic Automatic Transmission Fluid
- Severe Gear® 75W-140 Synthetic Gear Lube
- Slip Lock (Differential Additive)
- Ea® Oil Filter
The results were amazing. A recently published HOT ROD article states, “With the AMSOIL products installed, the Charger burned five tanks of fuel to establish an estimate of fuel mileage. Our fuel mileage with the AMSOIL product increased by 0.9 mpg...and the performance numbers were up as well. Peak torque was up 2.6 lb-ft and peak horsepower was up 4.4 hp.” The article goes on to say that “AMSOIL products are far superior to mineral oils in nearly every quantifiable category.”
This testing illuminates the advantages of AMSOIL synthetic lubricants. Synthetics help increase performance and engine life due to their...
- Ability to reduce energy lost to friction and maximize power and fuel economy
- Excellent film strength, which guards against wear in the toughest conditions
- Superior low-temperature pour point, helping reduce wear at startup
Here, HOT ROD sums up the case for making the switch to AMSOIL synthetic lubricants: “If you plan on keeping your machine on the road for years well beyond the warranty period, a synthetic like AMSOIL will keep bearings, rings, bores, lifters, cam lobes, valve guides, bands, clutches, and pumps running like new well past normal rebuild intervals, and that means money in your pocket.”
