GM dexos1 Gen 3 Licensed and Approved
GulfTEC Full Synthetic 0W-20 is specifically formulated to meet the performance requirements of GM dexos1 Gen 3.
The dexos1 Gen 3 specification was developed for gasoline engines and includes demanding requirements related to:
- Low-speed pre-ignition protection
- Turbocharger deposits
- Piston deposits
- Oxidation control
- Engine wear
- Fuel economy
- Sludge control
- Low-temperature performance
GM's current approved-oil directory continues to list GulfTEC Full Synthetic SAE 0W-20 as a licensed dexos1 Gen 3 product.
For GM vehicles requiring dexos1 Gen 3 and SAE 0W-20, this provides direct specification alignment rather than relying only on a general API service category.
Designed for Turbocharged and Direct-Injected Engines
Modern turbocharged gasoline direct-injection engines can place significant thermal and mechanical stress on engine oil.
They can also be susceptible to low-speed pre-ignition under certain operating conditions.
GulfTEC Full Synthetic 0W-20 is formulated to provide LSPI protection while helping maintain turbocharger and piston cleanliness.
This makes it suitable for compatible modern engines using:
- Gasoline direct injection
- Turbocharging
- Turbocharged direct injection
- Conventional port fuel injection
- Flex-fuel systems
Always verify that SAE 0W-20 and the listed performance specification are required by the vehicle manufacturer.
What Is LSPI?
Low-speed pre-ignition, or LSPI, is an abnormal combustion event that can occur in some turbocharged direct-injected gasoline engines, particularly under high load at relatively low engine speed.
An LSPI event can generate very high cylinder pressures and place additional stress on pistons, connecting rods and other engine components.
GulfTEC Full Synthetic dexos1 Gen 3 0W-20 is formulated to help protect against LSPI as part of its performance requirements.
API SP and ILSAC GF-6 Performance
The current GulfTEC Product Data Sheet identifies the 0W-20 formulation as suitable for use where the following are specified:
- API SP
- API SN PLUS
- API SN
- API SM
- ILSAC GF-6
- ILSAC GF-5
This allows the product to support many earlier gasoline-engine applications where SAE 0W-20 is the correct viscosity.
The current GulfTEC dexos1 Product Data Sheet does not list API SQ or ILSAC GF-7A, so those newer standards should not be assumed for this product without updated manufacturer documentation.
Ford WSS-M2C962-A1 Applications
For the SAE 0W-20 grade, GulfTEC lists compatibility where:
Ford WSS-M2C962-A1
is specified.
The other Ford specifications sometimes listed with the GulfTEC product family apply to different viscosity grades:
- WSS-M2C960-A1: 5W-20
- WSS-M2C961-A1: 5W-30
Those specifications should not be presented as specifications for this 0W-20 product.
GM Backward Compatibility
GulfTEC Full Synthetic dexos1 Gen 3 is designed to be backward compatible with previous model-year GM gasoline vehicles where the applicable viscosity and lubricant requirements allow it.
The PDS also identifies suitability for the obsolete GM specifications:
These older specifications are useful primarily as historical references for earlier vehicles.
Always follow the viscosity grade and lubricant specification listed in the vehicle owner's manual.
Passenger Cars, SUVs and Light-Duty Trucks
GulfTEC Full Synthetic 0W-20 is intended for compatible:
- Gasoline passenger cars
- Flex-fuel passenger cars
- Light-duty pickup trucks
- SUVs
- Crossovers
- Gasoline-electric hybrids
For hybrid vehicles, use the product only where the vehicle manufacturer specifies SAE 0W-20 and a compatible gasoline-engine oil specification.
Full Synthetic Protection
Full synthetic motor oils are designed to maintain performance over a broad range of temperatures and operating conditions.
GulfTEC Full Synthetic 0W-20 provides:
- Low-temperature fluidity
- Oxidation resistance
- Deposit control
- Wear protection
- Viscosity stability
- Low volatility
- High-temperature protection
These characteristics help maintain lubrication during both cold starts and normal operating temperatures.
Cold-Start Performance
The SAE 0W designation indicates performance at very low starting temperatures.
For GulfTEC Full Synthetic dexos1 Gen 3 0W-20, the current PDS lists a typical cold-cranking viscosity of:
5,700 cP at -35°C
It also lists a typical pour point of:
-42°C
These properties support lubricant circulation during cold starts. Actual engine starting performance also depends on battery condition, vehicle design and ambient temperature.
High-Temperature Performance
Although SAE 0W-20 is a low-viscosity engine oil, it must still maintain sufficient film strength at normal engine operating temperatures.
The current GulfTEC PDS lists:
- Kinematic viscosity at 100°C: 8.2 cSt
- High-temperature/high-shear viscosity at 150°C: 2.6 cP
- Flash point: 229°C
These properties characterize the oil's behavior under higher-temperature operating conditions.
Volatility and Oil Consumption
The current 0W-20 formulation has a typical Noack volatility of 10.5%.
Lower volatility helps reduce the amount of lubricant that can evaporate under high-temperature conditions, supporting oil-consumption control and deposit management.
Actual oil consumption varies by engine design, mileage, operating conditions and mechanical condition.
Current Specifications and Recommendations

- API SP
- API SN PLUS
- API SN
- API SM
- ILSAC GF-6
