Features and Benefits Of AMSOIL Signature Series 5W-30 Max-Duty Synthetic Diesel Oil
- Engine protection that surpasses industry standard by 600%
- Ultra-low volatility which minimizes oil usage
- Designed for long oil change intervals
- Excellent cold weather performance
- Withstands extreme heat and heavy loads
- Keeps engine internals clean
- Ideal for diesel or gasoline engines
Serious Wear Control
Signature Series 5W-30 Max-Duty Synthetic Diesel Oil was put through the tough Detroit Diesel DD13 Engine Scuffing Test. This synthetic 5W-30 outdid the minimum standard of this test by 600%. Despite being a 5W-30, expect wear control that rivals conventional 15W-40 diesel engine oils.
Maintains Viscosity And Combats Oil Consumption
Signature Series 5W-30 Max-Duty is designed to be exceptionally resistant to volatility. This means that it is not prone to “boil off” when exposed to extreme heat. Max-Duty 5W-30 also fights shear-down or thinning out under heavy loads. This engine oil offers steady viscosity protection throughout its service life.
Max-Duty 5W-30 pours down to -43°C, providing fast circulation during cold-starts. With Signature Series 5W-30’s exceptional resistance to extreme heat, it is a reliable choice for all four seasons.
A Versatile Performer
Signature Series 5W-30 Max-Duty is designed for diesel or gasoline engines, making it an ideal motor oil for fleets. It carries both the API CK-4 diesel and the API-SN passenger car/light truck spec. These specifications are “backward compatible” with previous generations of motor oil standards making it suitable for many older vehicles as well. See the complete motor spec list above.
Service Life Of AMSOIL Signature Series 5W-30 Max-Duty Synthetic Diesel Oil
Diesel Engine Oil Life Recommendations
Signature Series 5W-30 Max-Duty Synthetic Diesel Oil (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 Signature Series 5W-30 Max-Duty Synthetic Diesel Oil– 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 5W-30 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 engine oil additives is definitely not recommended.
