AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL The First in Synthetics® to do the best job protecting your engine.

EXTENDS DRAIN INTERVALS
AMSOIL HDD can extend drain intervals far beyond those recommended for conventional oils. Its unique synthetic formulation and long drain additive system deliver the best possible engine protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance and waste oil disposal costs.

MAXIMIZES FUEL ECONOMY
AMSOIL Synthetic 5W-30 Heavy Duty Diesel Oil is energy efficient for reduced fuel costs. Its low viscosity minimizes “drag” associated with high viscosity oils, allowing the engine to operate more freely, maximizing power and fuel economy.

UNSURPASSED PROTECTION AGAINST ENGINE WEAR
In the Four-Ball Wear Test (ASTM D-4172B) AMSOIL HDD demonstrated better anti-wear performance than competitive petroleum and synthetic oils. Even under high temperatures and pressures, its superior film strength and anti-wear additives help prevent metal-to-metal contact. AMSOIL HDD reduces ring wear, cylinder bore polishing, oil consumption and valve train wear for improved engine life and lower maintenance costs.

CONTROLS SOOT THICKENING AND WEAR
AMSOIL Synthetic 5W-30 Heavy Duty Diesel Oil is heavily fortified with detergent/dispersant additives and is naturally resistant to soot. It 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.

REDUCES OIL CONSUMPTION AND EMISSIONS
AMSOIL HDD loses only 6.7% of its mass to high temperature volatility (evaporation) in the NOACK test, outperforming all conventional oils. Because less oil vapor passes into the combustion chamber, oil consumption and emissions are reduced. Additionally, lower volatility helps AMSOIL HDD retain its viscosity after high temperature service for continued dependable protection and excellent fuel economy.

EXCELS IN EXTREME TEMPERATURES
AMSOIL Synthetic 5W-30 Heavy Duty Diesel Oil resists thermal (heat) breakdown, oxidation and sludge formation better than conventional oils. And unlike conventional petroleum oils, AMSOIL HDD contains no wax. It stays fluid down to -60°F for improved cold temperature oil flow, reduced bearing wear and easier starting.

APPLICATIONS
AMSOIL Synthetic 5W-30 Heavy Duty Diesel Oil is recommended for diesel engines and other applications requiring any of the listed worldwide specifications and gasoline engines requiring API SL, SJ, SH . . . or ACEA A3.

• API CI-4+, CF, CF-2, SL
• ACEA A3/B3, E2, E3, E5
• Global DHD-1 • JASO DH-1
• Mack EO-N Premium Plus ’03
• DDC Power Guard 93K214 • Caterpillar ECF-1
• Cummins CES 20071, 20072, 20076, 20077, 20078
• Volvo VDS-2, VDS-3 • MB 228.1, 228.3, 229.1
• MAN 3275
• MTU Type 1
• MIL-PRF-2104G
• Allison C-4

AMSOIL HDD is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for use with AMSOIL motor oils.

SERVICE LIFE
AMSOIL Synthetic 5W-30 Heavy Duty Diesel Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) vehicles or equipment as follows:

Personal Light Truck Diesel or Gasoline Engine Service

• Normal Service(3) – Up to 25,000 miles or one year, whichever comes first, or longer based on oil analysis.
• Severe Service(4) – Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.
• Replace AMSOIL Ea™ full flow oil filter or Donaldson Endurance™ ELF 7349 at the time of oil change up to 25,000 miles (other brands at standard OEM* intervals). Commercial or Fleet Vehicles, Long-Haul Trucks, Marine Craft, RV, Off-Road Equipment
• Non-EGR equipped diesels – extend drain intervals up to two times (2X) the OEM* recommended drain interval or one year, whichever comes first, or longer based on oil analysis.
• EGR equipped or low emission diesels – extend drain intervals based on oil analysis or use the OEM* recommended interval.
• Replace Donaldson Endurance™ or AMSOIL Ea™ full flow oil filters at the time of oil change up to two times (2X) longer than the OEM* standard interval, not to exceed 60,000 miles in long-haul trucks.

*OEM = Original Equipment Manufacturer

(1) Where the engine or operating conditions have been modified from the original manufacturers’ design, no oil change interval recommendation is made. Oil change intervals are at the owner’s discretion. Examples include the use of performance computer chips; modified exhaust, fuel or air induction systems and the use of fuels other than those recommended for normal operation by the manufacturers.

(2) Engines are in good working condition and within the factory design settings. Mechanically sound engines, for example, do not leak oil or consume excessive amounts, are not worn out, do not overheat, do not have internal or external anti-freeze leaks and have a properly working emission control system. AMSOIL recommends repairs be made to malfunctioning engines prior to the installation of AMSOIL synthetic oils.

(3) Personal transportation vehicles frequently traveling greater than 10 miles at a time and not operating under severe service.

(4) Diesel and gasoline engines – commercial or fleet vehicles, extensive engine idling, daily short trip driving less than 10 miles (16 km), frequent towing, plowing or hauling heavy loads, frequent driving in dusty conditions. Also, first and subsequent use of AMSOIL engine oil in gasoline engines with 100,000 miles or greater and turbo/supercharged gasoline engines.

AMSOIL Ea™ and Donaldson Endurance™ full flow oil filters are designed for extended drain intervals. They stop smaller particles, have less restriction and last longer than regular filters. For best performance, use AMSOIL Ea™ or Donaldson Endurance™ oil filters. Oil Analyzers Inc., 715-395-0222, is a division of AMSOIL
