It's our best choice for the Ford 6.0 liter Powerstroke!

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.

See the Updated Diesel Power Brochure for all AMSOIL Diesel Products.

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.

I prefer this oil for all my gasoline vehicles as well. It is the 100% Synthetic oil AMSOIL puts the most research into. It has a major advantage having the ability to retain it's viscosity throughout the abuse without going off of the chart. My gained mileage is consistent. This is also the best choice for older vehicles needing the anti-wear elements not found in GF-4 rated oils for those using 10W30 and 30WT oils. If you want a lower priced oil use the AMSOIL ACD 10W30 or the best seller AME 15W40.

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.

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.

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.

People call me all the time asking about black oil color. It doesn't matter if it's black. If you are within the life cycle of this 5W30 HDD, the detergents are doing their job. this oil has millions of miles of testing proving the claims. With AMSOIL your engine is protected against wear from soot and deposits guaranteed! See Service Life below..

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.

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.

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. (very few oils on the market meet the European ACEA requirements. Forget about the fraudulent API. If it doesn't list or meet any of the ACEA tests you ought to be asking questions or using a different oil.)

• API CI-4+, CF, SL • ACEA A3/B3, E2 • Global DHD-1 • JASO DH-1 • Mack EO-M+, EO-N Premium Plus ’03 • DDC Power Guard 93K214 • Caterpillar ECF-1-a, ECF-2 • Cummins CES 20071, 20072, 20076, 20077, 20078 • Volvo VDS-2, VDS-3 • MB 228.1, 228.3, 229.1 • MAN 271/3275 • MTU Type 2

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.

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:

Diesel Engine Service

  • Three times (3X) OEM* recommendation, not to exceed 50,000 miles/600 hours or one year, whichever comes first. Drain intervals may be extended further with oil analysis.

Gasoline Engine Service

  • Normal Service – Up to 25,000 miles or one year, whichever comes first, or longer based on oil analysis.
  • Severe Service – Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.

*Operating conditions and drain intervals for severe and normal service are defined by the OEM. Refer to your owner’s manual.

Note: Extended drain intervals are not recommended when using biofuels containing >10% ethanol or 5% biodiesel (B5). Follow OEM drain intervals or extend drain intervals with oil analysis.

(1) Modifications and Alterations – Engines operating under modified conditions are excluded from extended drain recommendations. Examples include the use of performance computer chips; non-OEM approved exhaust, fuel or air induction systems and the use of fuels other than those recommended for normal operation by the manufacturer.

(2) Mechanically sound engines are in good working condition and do not, for example, leak oil or consume excessive amounts, are not worn out, do not overheat, do not leak anti-freeze and have properly working emission control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL synthetic oils.

Diesel Engine Severe Service defined as extensive engine idling, daily short trip driving less than 10 miles (16 km), frequent towing, plowing, hauling or dusty condition driving.

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., is a division of AMSOIL that provides cost effective, quality oil analysis services.

AMSOIL Series 3000 5W30 Heavy Duty Diesel Oil Product Code HDD

Be sure to read and pass along this report from Lubes & Greases which is regarding the latest on the 3000 mile myth. Government figures are now speaking out on the problems involved with the long time "change your oil to be safe 3000 miles) which was old news in 1972 when AMSOIL entered the market.

Dealer Saves School District Time and Money With AMSOIL Products

Direct Jobbers John and Leah Kahrs of Hudson, Iowa know the savings potential of AMSOIL products; they also know that in these tough economic times, school districts need to save money as much as anyone.

Kahrs set his sights on making a customer of the Hudson Community School system back in 2006. There were a couple superintendent changes, but eventually Kahrs got an appointment and gave a third presentation to new superintendent Roark Horn. Kahrs made the presentation on the benefits and cost savings potential of AMSOIL. Horn was intrigued and agreed to register as a commercial account.

Kahrs first performed an oil analysis on all the buses to ensure they were mechanically sound and to get a baseline on the performance of the conventional oils they had been using.

In February 2008, Kahrs began converting the fleet of eight buses to AMSOIL Series 3000
Synthetic 5W-30 Heavy Duty Diesel Oil and AMSOIL Ea or Donaldson Oil Filters.

Before making the switch to AMSOIL, the school had a local school bus service shop perform oil changes based on recommended 3,000 to 4,000 mile intervals. The buses hold between 18 and 20 quarts of oil each. Combined, they are driven 64,000 miles annually, which equated to 16 conventional oil changes.

Since the conversion in 2008, only one bus has had the oil changed based on oil analysis results. This bus is running a C7 Caterpillar and the oil was changed after 20 months of service, 18,961 miles and 871 hours of engine operation.

“While the mileage may not seem significant, the results were pleasing,” Kahrs said. “These buses are severe service, driving mainly rural gravel roads that are soft, muddy and dusty.”

The other buses in the fleet still are running on the first AMSOIL oil change. Oil filter changes and oil analysis are performed annually or based on hours.
The school was spending $1,034 a year on conventional oil and filter changes, not including the costs of oil change labor or the driver’s time to take the buses in for oil changes.

“The AMSOIL conversion was a one-time cost of $1,238 and does not include oil change labor,” Kahrs said. “No driver time is required as oil changes were performed at the school bus shop after hours. This is a $1,034 annual savings in oil and filters alone. The savings to the environment is 80 gallons of used motor oil and 16 used oil filters.”

The district’s three vans, automobile and pickup also use AMSOIL products. “AMSOIL allows the vehicles to run through the school year without needing an oil change,” Kahrs said.

The buses and vehicles all use AMSOIL fuel treatments. AMSOIL diesel fuel treatments keep the buses running even in the cold of winter in northeast Iowa.

“Two years ago when neighboring school districts could not get their buses started in the 34-degrees below zero weather, Hudson’s buses all started and ran their routes,” Kahrs said. “All during the cold winter, no fuel-related or starting issues were experienced. “AMSOIL can save commercial accounts time and money and add value and productivity to their bottom line. No matter how big or small your commercial fleet is, AMSOIL will provide you with the performance and savings you need.”

Unsurpassed Diesel Engine Protection

Diesel engine emissions have been an ongoing environmental concern for the past few decades, and the United States, Europe and Japan have responded to demands to reduce harmful particulates and nitrogen oxides (NOx). In the U.S., particulate and NOx levels were first regulated in 1988, with regulations becoming increasingly stringent through the years. In fact, 1988 standards set NOx and particulate levels at 14.4 g/kWhr (grams/kilowatts – hour) and 0.8 g/kW-hr respectively, while 2010 standards have been set at 0.27 g/kW-hr and 0.013 g/kW-hr respectively. By 2010, diesel engines will be considered “clean,” but getting there will require sulfur-free fuel, improved in-cylinder combustion, exhaust after-treatment, vehicle design changes and diesel oils that are compatible with after-treatment systems.

Between the years 1988 and 1991, emission standards were met by improving in-cylinder combustion through the use of unit injectors, electronic controls, controlled air swirl, improved combustion bowl design, reduced piston crevice volume, turbo-charging, air inter-cooling and reductions in oil consumption.

The year 1991 also saw the use of high top rings to lower particulate emissions. By 1998, retarded fuel injection timing was introduced to meet increasingly stringent NOx emission standards. High top rings and retarded fuel injection timing increased soot loading on the oil, leading to the introduction of API diesel oil category CH-4 in order to prevent viscosity increases and increased wear due to soot.

In order to meet 2002 emission standards, most engine manufacturers introduced exhaust gas recirculation (EGR) engines, which recirculate a portion of the exhaust to the engine’s combustion chamber, lowering peak combustion temperature. Although EGR engines effectively reduce emissions, they also run hotter and introduce higher levels of soot and acid into the oil, leading to increased wear, increased oil viscosity and shorter oil drain intervals.

The API CI-4 diesel oil specification was introduced in December 2001 to protect against the higher temperatures and increased levels of acids, soot and oxidation associated with EGR engines, while some manufacturers released their own diesel oil performance specifications in order to assure optimum protection for their equipment. Mack released its stringent EO-N Premium Plus High Performance Diesel Engine Oil specification in the spring of 2002, then upgraded it to EO-N Premium Plus 03 in April 2003 due to soot-related oil thickening and shear that occurred after a certain length of highway time.

API issued an upgrade to its CI-4 specification, CI-4 PLUS, in September 2004 in order to provide improved oxidation resistance, shear stability, acid neutralization and soot dispersancy for EGR engines. CI-4 PLUS certified diesel oils also meet most of the individual manufacturer issued specifications and are backward compatible with older diesel oil specifications and engines. CI-4 PLUS oils must first meet the original requirements of CI-4, with the additional requirements of passing the 90-Pass Shear Stability Bench Test and the Mack T-11 engine test, a more stringent upgrade of the Mack T-8E soot-viscosity test required for CI-4.

In order to meet 2007 particulate standards, exhaust after-treatment devices such as particulate filters (DPF’s) and continuously regenerative traps (CRT’s) will be incorporated into diesel engines, creating new challenges for diesel oils. AMSOIL Synthetic Diesel Oils are ahead of the curve and ready to meet the challenges of tomorrow.

AMSOIL Synthetic Diesel Oils surpass the most stringent modern diesel oil specifications, including CI-4 PLUS and EO-N Premium Plus 03. Formulated with top-of-the-line synthetic base stocks and advanced additive packages, AMSOIL Synthetic Diesel Oils effectively control the increased soot and acid levels associated with EGR units, while remaining shear stable at high temperatures, avoiding the damaging sludge and deposit build-up that contribute to decreased fuel efficiency, corrosion and accelerated engine wear. The drain intervals of AMSOIL diesel oils may be extended by oil analysis in EGR-equipped engines.

Emission control technology has increased soot loading of diesel oils, prompting original equipment manufacturers to shorten drain interval recommendations. Even at increased soot levels, AMSOIL Synthetic Diesel Oils continue to offer outstanding wear protection. Soot and iron wear levels were measured over 900 hours of operation in a 2002 EGR-equipped Mack LE613-Rear Loader running AMSOIL 15W-40 Synthetic Heavy Duty Diesel and Marine Motor Oil. Even at increased soot levels, the rate of engine wear remained well below the Mack condemnation limit of 0.5 parts per million per hour (ppm/h).
