AMSOIL Synthetic Lubricants Provide 8.2% More MPG At the request of AMSOIL INC., an independent research institute conducted a month-long test comparing the fuel consumption of class 8 diesel trucks equipped with AMSOIL synthetic lubricants to that of class 8 diesel trucks equipped with conventional lubricants. The research institute used the SAE J1321 Joint TMC-SAE Fuel Consumption Test Procedure Type II, an industry standard test for comparing in-service fuel consumption of test and control vehicles. Carefully matched vehicles traveled a route representative of typical long-haul interstate highway operations. Conditions including speed, tire pressure, headlight and fan use and window opening were held constant, and testing proceeded only when wind and temperature conditions were within testing guidelines. The test vehicles were equipped with AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil in the engines, AMSOIL Series 2000 20W-50 Racing Oil in the transmissions and AMSOIL Series 2000 Synthetic 75W-90 Gear Lube in the drive axles. The controls were equipped with Shell Rotella T 15W-40 in the engines, Quaker State SAE 90 in the transmissions and Citco 85W-140 in the drive axels. The trucks were equipped with auxiliary weigh fuel tanks and quick disconnect couplings to facilitate accurate data gathering. The weight of fuel consumed by the control and test vehicles after each driving segment was compared. Results were evaluated according to accepted statistical practices. Findings The vehicles equipped with AMSOIL synthetic lubricants demonstrated up to an 8.2 percent increase in miles per gallon (mpg) over the mpg obtained by the vehicles equipped with the control lubricants. Data showed mpg increases up to 3.42 percent comparing engine oils alone. What Does a Savings of 8.2% Mean? Imagine a fleet of 100 class 8 vehicles traveling an average 120,000 miles per year at an average of 6.5 mpg with diesel fuel at $1.20 a gallon. The fleet spends an annual $2,215,385 on fuel. Now imagine the fleet uses AMSOIL products and improves its miles-per-gallon by 8.2 percent. The fleet now spends @2,047,490 on fuel annually. That's a savings of $167,894.

Superior Oils for Superior Profits

In 1972, AMSOIL INC. introduced AMSOIL Synthetic 10W-40 Motor Oil and became the first company in the world to market and manufacture an American Petroleum Institute (API) rated synthetic motor oil. In 1975, AMSOIL introduced a synthetic diesel oil, and with it, coined the term "extended drain intervals."

Since then, AMSOIL synthetic diesel oils have been used as extended drain lubricants in transportation, equipment and stationary engine applications. In every industry, they have proven effective in improving engine durability and fuel economy. AMSOIL customers report significant savings realized through reductions in downtime, parts replacement, lubricant replacement, lubricant disposal and fuel consumption. Fleet demonstrations and independent testing confirm what AMSOIL customers report: using AMSOIL synthetic diesel oils saves money.

Superior Performance

AMSOIL synthetic diesel oils lubricate and protect diesel engines better than conventional lubricants do.

Volatility - AMSOIL synthetic diesel oils' volatility is exceptionally low which keeps oil consumption rates low and inhibits oil thickening. For example AMSOIL Synthetic 15W-40 Heavy Duty Diesel and Marine Oil loses only 6 percent of its mass to volatility in the Noack Volatility Test. Other popular 15W-40 oils lose as much as 13.96 percent.

Thermal Stability - The excellent thermal stability of AMSOIL synthetic diesel oils helps keep oil oxidation rates low, inhibits sludge formation and ensures proper engine lubrication and protection. It is a critical factor in safely extending oil drain intervals.

Oxidation Resistance - AMSOIL synthetic diesel oils' outstanding oxidation resistance keeps engines cleaner longer for efficient operation and long life. Oxidation resistance is also a critical factor in extended drain intervals.

Low Temperature Performance - The cold temperature fluidity of AMSOIL synthetic diesel oils enables cold engines to start easily, protects cold engines from premature wear after engine startup, promotes excellent cold temperature fuel economy and eliminates or reduces the need for inventories of seasonal oils.

Superior Protection

Fully formulated motor oils contain additives that perform functions the lubricating oil basestocks alone can't perform. For example, detergent-alkalinity additives inhibit the formation of deposits on hot engine surfaces and neutralize acids. Dispersants inhibit wear caused by soot and debris. Viscosity index improvers give lubricants multi-grade viscosity. Other additives inhibit lubricant oxidation, metal oxidation, rust and foam or prevent component damage when a full film of lubricant isn't present to prevent it.

AMSOIL synthetic diesel oils are formulated with the highest quality additives available to ensure proper lubrication and protection in extended drain use.

Wear Protection - Wear protection is provided by the lubricating oil in areas where a full lubricating film develops between moving parts, such as the bearings. It is provided by anti-wear additives in areas where a full film does not develop, such as the valve train.

The Four Ball Wear Test (ASTM D4172B), a test designed to measure the effectiveness of anti-wear additive systems, shows AMSOIL Series 3000 Synthetic 5W-30 Heavy Duty Diesel Oil produced wear scars as much as 39 percent smaller than those produced by competing petroleum and synthetic diesel oils. That's significantly better wear protection.

Shear Stability - Some VI improvers break down in demanding operating conditions. When an oil's VI improver breaks down or shears, the oil no longer retains its intended viscosity over its intended temperature range, rendering the oil unable to protect the engine from premature wear in high temperatures.

AMSOIL synthetic diesel oils are highly shear stable. Shear stability is especially important for engines that operate at constant speed, such as stationary engines, marine engines and farm tractors.

TBN and Detergent-Alkalinity - AMSOIL synthetic diesel oils are formulated with 12 Total Base Number (TBN), a high value designed to provide superior control of corrosion and high temperature deposits in extended drain service. Most conventional diesel oils' TBN equals 8.

AMSOIL synthetic diesel oils' highly effective detergent-alkalinity additives help piston crownlands and compression ring zones stay clean, inhibit bore polishing and piston deposits, minimize cylinder liner wear, minimize ring wear and breakage, and help keep oil consumption rates low.

The ability of AMSOIL synthetic diesel oils to maintain high TBN values sets these oils apart as superior extended drain lubricants.

Dispersancy - Dispersants control soot and other contaminants and inhibit the formation of sludge and deposits on low temperature areas, such as the piston skirts and adjacent areas.

Lasting control of soot, other contaminants and low temperature deposits are an integral element of AMSOIL synthetic diesel oils' extended drain capabilities.

Complete Protection - AMSOIL synthetic diesel oils also contain antifoamants to prevent persistent oil foaming, anti-rust agents to inhibit rusting and anti-oxidants and metal deactivators, both of which retard oxidation processes.

Superior Profitability

AMSOIL synthetic diesel oils save diesel operators money through increased fuel economy, increased engine durability, reduced oil inventories and extended lubricant drain intervals.

Fuel Economy - Independent testing and fleet demonstrations show engines equipped with AMSOIL synthetic diesel oils operate with better fuel economy than engines equipped with other diesel oils do. Fuel mileage improvements in excess of three percent have been documented in independent testing.

Engine Durability - Fleet demonstration oil analyses comparing the performance of AMSOIL synthetic diesel oils to competitive products show lower rates of wear metal generation with AMSOIL products. Engine part inspections confirm the outstanding wear protection provided by AMSOIL synthetic diesel oils. Lower rates of engine wear improve engine durability, providing longer intervals until first engine teardown, greater intervals between overhauls and longer engine life.

Oil Inventories - The outstanding low temperature fluidity and high temperature protectiveness of AMSOIL synthetic diesel oils eliminate the need for special inventories of seasonal oils. AMSOIL synthetic diesel oils are also formulated for use in gasoline engines, to separate oils for diesel and gasoline engines are also unnecessary.

Extended Drain Intervals - AMSOIL synthetic diesel oils bear the Mack EO-M,Volvo VDS and VDS 2 labels, showing they meet Volvo's demanding extended drain performance results and the experiences of owner-operators confirm that AMSOIL synthetic diesel oils provide excellent extended drain service.
