Robust Wear Protection

With the trend toward lighter viscosity diesel oils in heavy-duty engines, many have concerns about increased wear. The Signature Series Max-Duty formula was developed to provide unparalleled wear protection. It aces the Detroit Diesel DD13 Scuffing Test, beating the minimum standard by 600%. This elite diesel 10W-30 contains the finest base oils and additives to maximize diesel engine life.

Fights Oil Consumption

Signature Series Max-Duty 10W-30 Synthetic Diesel Oil is designed to have a very high resistance to volatility boil-off. It prevents thinning and shearing down for steady viscosity protection. ThisAMSOIL Signature Series Diesel Oil Consumption Chart product is formulated to stay in grade when exposed to heavy loads, extreme heat and long service intervals.

All-Season Capable

Signature Series Max-Duty 10W-30 Synthetic Diesel Oil has a cold-pour point of -42°C (-44°F). It flows quickly during cold starts. In extreme heat, this full synthetic 10W-30 fights shear-down for consistent engine protection.

Service Life Of AMSOIL Signature Series Max-Duty 10W-30 Synthetic Diesel Oil

Diesel Engine Oil Life Recommendations

Turbo-Diesel Pick-up Trucks (except 2007-2010 models)– Up to 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 Power Stroke 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 potential 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 Max-Duty 10W-30 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.
