AMSOIL Diesel Products For 2007 & Older Diesel Engines Requiring API CI-4+

AMSOIL Series 3000 100% Synthetic 5W-30 Diesel OilSeries 3000 100% Synthetic Amsoil 5W-30 Diesel Oil (HDD)
AMSOIL 5W-30 diesel oil is one of AMSOIL’s most robust products. HDD heavy duty formulation outwears most 15W-40′s, exceeding the higher performance demands of modern engines while providing better fuel economy. AMSOIL 5W-30 diesel oil is heavily fortified with detergent/dispersant additives and is naturally resistant to soot. AMSOIL 5W-30 diesel oil will stay fluid down to -51°C for reduced bearing wear and easier starting. It also resists heat breakdown, oxidation and sludge formation better than conventional diesel oils.


AMSOIL Synthetic Heavy Duty Diesel & Marine Motor OilSynthetic 15W-40 Heavy Duty Amsoil Diesel & Marine Motor Oil (AME)
AME AMSOIL 15W-40 diesel oil is engineered for all types of diesel engines with an emphasis on modern, low emission heavy duty diesel engines. The high 12 TBN controls acids from combustion blow-by and EGR. High levels of detergency and dispersancy additives control soot thickening, oxidation and wear. AME AMSOIL 15W-40 diesel oil will successfully keep soot particles independently suspended and prevent them from attaching together to form larger, and more wear-causing particles. AME AMSOIL 15W-40 diesel oil will also remain fluid down to -42°C and minimize viscosity increase.


AMSOIL Synthetic 10W-30/SAE 30 Diesel OilSynthetic 10W-30/SAE 30 Amsoil Diesel Oil (ACD)

Unlike conventional SAE 30 motor oils, AMSOIL ACD diesel oil has a naturally high viscosity index and does not contain paraffin (wax). It has a -37°C pour point and qualifies for SAE 10W, making it an “all season” multi-grade lubricant with a wide operating temperature range.
