AMSOIL Products for your Duramax 
AMSOIL Synthetic 5W-40 Premium Diesel Oil (DEO)
AMSOIL Synthetic 5W-40 Premium Diesel Oil (DEO) is 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. AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil (HDD)In a head-to-head comparison, Series 3000 provided better wear protection than Delvac 1, Delo 400, Rotella T, and Valvoline Premium Blue. Independent laboratory testing shows up to 40 percent less wear with Series 3000 than with the other oils tested. AMSOIL Series 3000 100% Synthetic 5W-30 Diesel Oil (HDD) delivers extraordinary lubrication in both diesel and gasoline engines found in commercial, fleet and personal vehicles. By combining the industry’s premier synthetic technology with AMSOIL premium additives, AMSOIL HDD exceeds the higher performance demands of modern engines. It withstands the stress of higher heat, higher acid levels and excessive soot loading found in EGR equipped engines. AMSOIL Series 3000 Synthetic 5W-30 Diesel Oil consistently outperforms conventional and synthetic diesel oils for long-lasting performance and protection. AMSOIL 15W-40 Oils (AME) AMSOIL Synthetic Heavy-Duty Diesel and Marine 15W-40 Motor Oil (AME) and AMSOIL Synthetic Blend 15W-40 Motor Oil (PCO) have been put to the test over millions of miles in heavyduty trucks. They are proven to provide unsurpassed engine protection, even when they are used much longer than conventional diesel oils are used. Numerous tests have proven that AMSOIL maintains its protective TBN and viscosity while petroleum products rapidly lose both. More to the point, AMSOIL keeps engine wear rates low, an important factor in ensuring long engine life. AMSOIL Ea Oil Filters (EaO)
Made with premium-grade full synthetic media. Ea Oil Filters feature advanced full synthetic nanofiber technology, making them the highest efficiency filters that are available for the auto/light truck market. AMSOIL EaO Filters are guaranteed for 25,000 miles or one year, whichever comes first, when used in conjunction with AMSOIL Synthetic Motor Oil in gasoline and diesel vehicles in normal service, 15,000 miles in severe service. Contact Mike for more information AMSOIL Ea Air Filters AMSOIL Ea Air Filters (EaA) are the most efficient filters available to the car/light truck market. Ea Air Filters’ synthetic nanofiber media removes 5 times more dust than traditional cellulose filter media alone and 50 times more dust than wet gauze filter media. AMSOIL Ea Air Filters have a service life of 100,000 miles or four years, whichever comes first. AMSOIL Ea By-Pass Filtration By-Pass Filtration Benefits • Dramatically Extended Drain Intervals

The AMSOIL Dual Remote Oil Filtration System converts an engine’s full-flow oil filter system into
a full-flow/by-pass oil filtration system by attaching an AMSOIL Full-Flow Oil Filter and AMSOIL
Spin-On By-Pass Oil Filter onto a remote mount. The Dual Remote System provides superior filtration efficiency, increased oil capacity and improved oil filtration accessibility. See the G1092 brochure for more info on the Dual Remote Filtration System. Diesel Concentrate Performance Fuel Additive (ADF)
Total system cleaner and lubricity improver for all types of diesel engines. Improves the performance, fuel efficiency and longevity of diesel engines while reducing deposits, black smoke and emissions. Improves fuel economy by cleaning dirty injectors and restores horsepower. Designed for use in heavy-duty diesel engines. Package sizes include: 16-oz. Bottle
16-oz. Bottles (case of 12)
5-Gallon Pail
55-Gallon Drum Product Description
AMSOIL Diesel Concentrate (ADF) provides maximum diesel operating efficiency. It compensates for the variances in quality of different fuels (including biodiesel) and the deficiencies of today’s Ultra Low Sulfur Diesel fuel (ULSD) for better engine operation. New engine technology, tighter tolerances and emission regulations require high-quality diesel fuel for long-term engine operability. AMSOIL Diesel Concentrate meets the low sulfur mandate. It improves diesel fuel quality to exceed today’s stringent performance requirements. AMSOIL Diesel Concentrate extends equipment life, lowers operating costs and improves diesel performance. Diesel Cold Flow Improver (DFF)
A premium fuel additive that lowers diesel fuel cold flow properties as much as 20°F (11°C). Package sizes include: 16-oz. Bottle
16-oz. Bottles (case of 6)
5-Gallon Pail
55-Gallon Drum PRODUCT DESCRIPTION
AMSOIL Cold Flow Improver for diesel fuel is designed for use in Ultra Low Sulfur Diesel fuel (ULSD) and conventional fuels. It functions by modifying wax crystal formation at low temperatures to depress the pour point and improve cold flow filtration properties. AMSOIL Cold Flow Improver contains jet fuel-type deicer to help prevent ice formation in fuels contaminated with water. It is recommended for use with all diesel engines and is compatible with diesel exhaust particulate filters (DPFs). AMSOIL Cold Flow Improver is recommended for use in #2 diesel fuel, #1 diesel fuel, kerosene, heating oil and biodiesel. Add AMSOIL Cold Flow Improver to diesel fuel above the fuel cloud point, which is the temperature wax crystals begin to form. Diesel fuel cloud point varies greatly with some lesser-quality diesel fuels forming wax as warm as 40° F (4°C). AMSOIL recommends treating diesel fuel at a minimum of 32°F (0°C), insuring the fuel is properly treated inmost every case. AMSOIL Cold Flow Improver is designed to control wax crystal formation. It does not reverse wax or gel once formed. Cetane Boost Diesel Fuel Additive (ACB)
An ashless, alcohol-free additive that improves cetane up to seven points for increased power and performance in all diesel engines. Package sizes include: 16-oz. Can
5-Gallon Pail
55-Gallon Drum PRODUCT DESCRIPTION
AMSOIL Cetane Boost Additive improves diesel fuel quality that benefits all diesel engines, especially high performance designs. Supported by extensive testing and years of field trial use, AMSOIL Cetane Boost Additive has repeatedly demonstrated its ability to improve diesel engine performance. High performance diesel engines operate best with cetane values of 50 or higher. |
