Resists Cylinder Bore and Piston Ring Wear
Signature Series 0W-40 Max-Duty Synthetic Diesel Oil was put through the Detroit Diesel DD13 Engine Scuffing Test. Its powerful anti-wear chemistry enabled it to beat the minimum standard of this test by 600%. Expect world-class wear protection from this 100% synthetic 0W-40.
Fights Heat and Volatility Oil Loss
Although some may presume that a 0W-40 is for winter only, nothing could be further from the truth. The volatility of this AMSOIL Signature Series product is 76% below the API CK-4 threshold. It offers a strong resistance to shear down and boil-off for consistent protection during extreme heat and heavy loads.
Outstanding Winter Weather Protection
With a cold-pour-point of -48°C (-54°F), Signature Series 0W-40 Max-Duty Synthetic Diesel Oil delivers fast oil circulation on those cold morning starts.
Service Life Of AMSOIL Signature Series 0W-40 Max-Duty Synthetic Diesel Oil
Diesel Engine Oil Life Recommendations
Turbo-Diesel Pick-up Trucks (except 2007-2010 models)– Two times the manufacturer’s oil change interval to a maximum of 40,000 km/25,000 miles or one year.
2007-2010 Dodge/Cummins 6.7L, Ford PowerStroke 6.4L, GM Duramax 6.6L– Must follow the manufacturer’s oil change interval. This is due to potential fuel dilution issues.
Heavy Duty Engines/Off-Road Equipment– Three times the manufacturer’s oil change interval to a maximum of 40,000 km/60,000 miles or 600 hours or one year (whichever comes first).
2007- 2009 Caterpillar C13 and C15 Highway Engines– Must follow the manufacturer’s oil change interval. This is due to excessive fuel dilution.
Note: Do not extend oil change intervals when vehicle is operated in the following situations. Oil change intervals may be extended when supported with oil analysis.
- Severe service applications (see vehicle owner’s manual for “severe service” definition).
- When engine is heavily modified.
- When 15% biodiesel (B15) is used.
Gasoline Engine Oil Life Recommendations
Up to two times the oil change interval as recommended by your owner’s manual to maximum of 15,000 miles (24,000 km) or one year, whichever comes first.
Note: When using gasoline with an ethanol content of greater than 10%, follow the manufacturer’s oil change interval or support with oil analysis.
Mixing AMSOIL Synthetic Diesel Engine Oil With Other Brands
AMSOIL Signature Series 0W-40 Max-Duty Synthetic Diesel Oil is compatible with all other brands of conventional, semi-synthetic and synthetic diesel engine oils. While you can safely mix AMSOIL Synthetic Diesel Oil with other brands, this will reduce the drain interval and performance capabilities of AMSOIL diesel oil.
The use of any aftermarket diesel engine oil additives is definitely not recommended.
