AMSOIL Diesel Engine Oils

AMSOIL offers the most modern and complete line of synthetic oil, filtration and fuel additives for today’s diesel trucks. AMSOIL’s robust synthetic lubricants provide lower operating temps for hauling and very low cold pour points for those winter cold-cranking situations.

For Model Year 2007 & Newer Requiring API CJ-4

Synthetic 5W-40 Premium Diesel Oil “API CJ-4″ (DEO)

The premium choice diesel oil for model year 2007 and newer heavy-duty and pickup truck diesel engines requiring API CJ-4 emission quality oil standards. It withstands the stress of heat, soot and acids to help prevent deposits, corrosion and wear. AMSOIL Synthetic 5W-40, with its broad viscosity range, is ideal for winter and summer use.

Synthetic 15W-40 Premium Diesel Oil “API CJ-4″ (DME)

The premium choice for API CJ-4 emission-quality 15W-40 diesel oil required by model-year 2007 and newer diesel engines. A low-sulfated ash formulation that provides excellent performance in low-emission diesel engines. It is compatible with all exhaust treatment devices and is designed to extend the service life of diesel particulate filters. Provides maximum protection for up to 3 times the OEM-recommended drain interval, and further with oil analysis.

OE 15W-40 Synthetic Diesel Oil “API CJ-4″ (OED)

A value-priced synthetic 15W-40 meeting the API CJ-4 specification. For on- or off-road service. Designed for a drain interval as recommended by the vehicle manufacturer. AMSOIL performance and protection at a great price.

For Pre-2007 On-Road or All Model Years Off-Road

Series 3000 100% Synthetic 5W-30 Diesel Oil (HDD)

One of AMSOIL’s most robust products. HDD exceeds the higher performance demands of modern engines. Ultra heavy duty formulation outwears most 15W-40′s, while providing better fuel economy. Heavily fortified with detergent/dispersant additives and is naturally resistant to soot. Stays fluid down to -51°C for reduced bearing wear and easier starting. Resists heat breakdown, oxidation and sludge formation better than conventional oils.

Synthetic 15W-40 Heavy Duty Diesel & Marine Motor Oil (AME)

Engineered for all types of diesel engines with an emphasis on modern, low emission heavy duty diesel engines. High 12 TBN controls acids from combustion blow-by and EGR. High levels of detergency and dispersancy additives control soot thickening, oxidation and wear. Keeps soot particles suspended independently, preventing them from attaching together to form larger, wear-causing particles. Viscosity increase is minimized and soot related wear is controlled. Remains fluid down to -42°C.

Synthetic Blend 15W-40 Heavy Duty Motor Oil (PCO)

This multi-use oil is designed for both heavy-duty diesel engines (including modern EGR units) and gasoline engines, combining versatility and heavy-duty engine protection into one cost effective motor oil. It is formulated with high levels of dispersant and detergent additives that effectively control acids and soot thickening to prevent corrosion, wear and deposits.

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

Formulated with premium synthetic base oils that exceed both 10W-30 multi-grade and SAE 30 straight-grade viscosity requirements for outstanding performance in modern and older diesel engines. Unlike conventional SAE 30 motor oils, AMSOIL ACD 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.

European Car Formulas For Diesel Engines

Specially formulated for the lubrication needs of modern European diesel and gasoline cars. Meets a multitude of diesel specifications for Volkswagen and Mercedes Benz. 5W-40 meeting VW 502.00, 505.00, 505.01, Mercedes Benz 229.31, 229.51 or 5W-30 meeting VW 504.00/507.00, MB 229.51.
