\"\"Commercial Grade Diesel Oil<\/strong><\/a><\/p>\n

 <\/p>\n

Heavy-Duty Engine Protection<\/span><\/strong><\/p>\n

Wear on rings and cylinder liners leads to increased oil consumption and loss of compression, resulting in reduced horsepower and fuel economy. Third-party testing shows AMSOIL Commercial-Grade Diesel Oil delivers 2X more wear protection1 to help maximize equipment life and reduce maintenance costs and downtime.<\/p>\n

\n

Viscosity Control<\/span><\/strong><\/p>\n

Formulated with greater than 50% synthetic content and high-performance detergent\/dispersant additives, AMSOIL Commercial-Grade Diesel Oil minimizes viscosity change while keeping soot particles suspended independently, helping prevent the formation of larger, wear-causing particles.<\/p>\n

\n

Minimizes Oil Consumption<\/span><\/strong><\/p>\n

AMSOIL Commercial-Grade Diesel Oil has a low rate of volatility (burn-off), reducing oil consumption during operation and passing less oil vapor into the combustion chamber. This contributes to fewer combustion-chamber deposits and longer aftermarket-system life.<\/p>\n

\n

Excels in Extreme Temperatures<\/span><\/strong><\/p>\n

AMSOIL Commercial-Grade Diesel Oil is formulated to deliver improved heat and oxidation resistance compared to conventional diesel oils. It provides clean engine operation and helps maintain power and fuel efficiency for strong engine performance. AMSOIL Commercial-Grade Diesel Oil also flows dependably in cold temperatures for reliable startup and engine protection.<\/p>\n

\n

APPLICATIONS<\/span><\/u><\/strong><\/p>\n

Use in diesel engines and, where appropriate, gasoline engines requiring any of the following specifications:<\/p>\n

API CK-4, CJ-4, CI-4+, CH-4; Cummins CES20086, CES20081; Caterpillar ECF-3, ECF-2, ECF-1-a; DDC 93K215, 93K214;<\/span> ACEA E9, E7; MB 228.31; JASO DH-2; Deutz DQC II-10LA;<\/span> Ford WSS-M2C171-F1<\/span><\/p>\n

\n

COMPATIBILITY<\/u><\/span><\/strong><\/p>\n

AMSOIL Commercial-Grade Diesel Oil is compatible with other conventional and synthetic oils. Mixing AMSOIL diesel oil with other oils, however, will reduce its performance benefits.<\/p>\n

Aftermarket oil additives are not needed or recommended<\/b> for use with AMSOIL diesel oils.<\/p>\n

\n

SERVICE LIFE<\/span><\/u><\/strong><\/p>\n

AMSOIL Commercial-Grade Diesel Oil is recommended for the drain intervals stated by the original equipment manufacturer (OEM). Refer to the owner\u2019s manual for the specific oil change interval. Intervals may be extended beyond the OEM recommended interval with oil analysis.<\/p>\n
