Maximum Engine Protection
Wear on rings and cylinder liners leads to increased oil consumption
and loss of compression, resulting in reduced horsepower and fuel
economy. Independent testing shows AMSOIL Signature Series Max-Duty delivers 6X more wear protection than required by the Detroit
Diesel DD13 Scuffing Test for Specification DFS 93K222, delivering
the security of providing your diesel the extra protection it deserves.
Using top-tier synthetic base oils, AMSOIL Signature Series Max-Duty is naturally resistant to oxidation and the thickening effects of
soot contamination. That, along with boosted detergent/dispersant
additives, keeps soot particles suspended independently, helping
prevent the formation of larger, wear-causing particles. Viscosity
increase is minimized and soot-related wear is controlled. Lower
volatility also helps Signature Series Max-Duty retain its viscosity
after high-temperature service for maximum engine protection and
Excels in Extreme Temperatures
AMSOIL Signature Series Max-Duty Synthetic Diesel Oil resists thermal
(heat) breakdown better than conventional and competing synthetic
diesel oils. Unlike conventional oils, Signature Series contains no wax,
staying fluid in sub-zero temperatures for easier starting, improved oil
flow and reduced wear.
Minimizes Oil Consumption
AMSOIL Signature Series Max-Duty has a low rate of volatility (burn-off),
reducing oil consumption during operation and passing less
oil vapor into the combustion chamber. It provides up to 76 percent
less oil consumption than required by the API CK-4 standard in the
Caterpillar-1N oil consumption test.

- DDC 93K218, 93K215, 93K214
- DFS 93K222
- ACEA E9, E7
- MB 228.31
- MAN 3575
- MTU Type 2.1, II, I
- JASO DH-2

- Scania LA-2
- Chrysler MS 10902
- Ford WSS-M2C171-F1
AMSOIL Signature Series Max-Duty Synthetic Diesel Oil is compatible with other conventional and synthetic engine oils. Mixing AMSOIL diesel oils with other oils, however, will shorten the oil’s life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.
Aftermarket oil additives are not recommended for use with AMSOIL synthetic diesel oils.
Diesel Engine Service Life
Heavy-Duty On-/Off-Road: Three times (3X) OEM1 recommendation, not to exceed 60,000 miles/600 hours or one year, whichever comes first.
Turbodiesel Pickup: Two times (2X) OEM1 recommendation, not to exceed 25,000 miles or one year, whichever comes first.
Gasoline Engine Service Life
Two times (2X) OEM1 recommendation, not to exceed 15,000 miles or one year, whichever comes first.
Drain intervals may be extended further with oil analysis.
1Refer to your owner’s manual for OEM drain interval recommendations and guidelines for severe and normal service.
Note: Extended drain intervals are not recommended for performance-modified engines, when using biofuels containing more than 10 percent ethanol or 15 percent biodiesel (B15) or for 2007-2009 Caterpillar* C13 and C15 on-highway engines. Extend drain intervals beyond OEM recommendations in these instances only with oil analysis. Note: 2007-2010 Dodge**, Ford** and GM** turbodiesel pickups are also not recommended for extended drain intervals when using DHD.
