AMSOIL 10W-30 Commercial-Grade Diesel Oil is an advanced synthetic-blend formulation built to deliver real protection upgrades for commercial trucks, fleet vehicles, and heavy equipment without the cost of a full-synthetic product. With greater than 50% synthetic base oil content, it provides 2X more wear protection than required by the Detroit Diesel DD13 Scuffing Test for specification DFS 93K222, verified through independent third-party testing.
Diesel engines in commercial service face punishing conditions. High soot loads, extreme operating temperatures, and long hours under load all work against the oil's ability to protect rings, cylinder liners, and bearings. When wear accelerates in these critical areas, the result is increased oil consumption, lost compression, reduced horsepower, and higher fuel costs. A conventional diesel oil may meet minimum specifications, but minimum protection is not the same as adequate protection for engines expected to run hundreds of thousands of miles.
2X MORE WEAR PROTECTION
Ring and liner wear is the root cause of many expensive diesel engine problems, from blow-by and oil consumption to compression loss and reduced fuel economy. AMSOIL 10W-30 Commercial-Grade Diesel Oil delivered 2X more wear protection than the threshold required by Detroit Diesel's DD13 Scuffing Test for specification DFS 93K222. That testing was conducted by a third party using the 10W-30 viscosity as the worst-case representation. For fleets running Kenworth, Peterbilt, Freightliner, or International trucks with Detroit Diesel DD13, DD15, or DD16 engines, this level of scuffing resistance translates directly to longer engine life and fewer unplanned rebuilds.
VISCOSITY CONTROL UNDER HIGH SOOT LOADS
Diesel engines generate soot as a normal byproduct of combustion, and that soot ends up in the oil. When soot particles clump together, they thicken the oil and cause abrasive wear. AMSOIL Commercial-Grade Diesel Oil uses high-performance detergent and dispersant additives to keep soot particles suspended independently, preventing the formation of larger, wear-causing agglomerations. The greater than 50% synthetic content also helps the oil resist viscosity change over time, maintaining its protective film strength throughout the drain interval. The 10W-30 grade posts a viscosity index of 145 (ASTM D2270), indicating strong viscosity stability across a wide temperature range.
EXCELS IN TEMPERATURE EXTREMES
Commercial diesel engines operate across a broad spectrum of conditions, from sub-zero cold starts in northern climates to sustained high-temperature operation during summer hauling. AMSOIL 10W-30 Commercial-Grade Diesel Oil is formulated to deliver improved heat and oxidation resistance compared to conventional diesel oils, helping maintain clean engine internals and consistent power output. Cold-cranking viscosity measures 5960 cP at -25°C (ASTM D5293), and the pour point reaches -38°C (-36°F), so the oil flows reliably during cold-weather startups on Cummins ISX-powered trucks, Caterpillar equipment, or Ford 6.7L Power Stroke diesel pickups sitting overnight in freezing temperatures.
MINIMIZES OIL CONSUMPTION
Oil volatility, the tendency of lighter molecules to evaporate under heat, is a significant contributor to oil consumption in diesel engines. AMSOIL Commercial-Grade Diesel Oil posts a NOACK volatility of 4.8% weight loss (ASTM D5800) in the 10W-30 grade, reducing the amount of oil vapor that passes into the combustion chamber. Less oil burn-off means fewer combustion-chamber deposits and longer aftertreatment system life, particularly for diesel particulate filters and diesel oxidation catalysts on newer emissions-equipped trucks.
BROAD OEM SPECIFICATION COVERAGE
AMSOIL 10W-30 Commercial-Grade Diesel Oil meets or exceeds a wide range of OEM requirements for both on-road and off-road diesel applications:
This makes it a direct fit for a wide range of equipment, from a Ram 2500 with the 6.7L Cummins to a CAT excavator, a Mack Anthem, or a Volvo VNL long-haul tractor. It is also suitable for gasoline engines requiring any of the listed specifications.
COMPATIBILITY
AMSOIL Commercial-Grade Diesel Oil is compatible with other conventional and synthetic diesel oils. Mixing with other oils will reduce its performance benefits. Aftermarket oil additives are not needed or recommended.
SERVICE LIFE
AMSOIL 10W-30 Commercial-Grade Diesel Oil is recommended for the oil change intervals stated by the original equipment manufacturer. Intervals may be extended beyond the OEM-recommended interval with oil analysis.
