Improve Fuel Economy

Use of AMSOIL synthetic lubricants, Ea Air Filters and fuel additives help customers stretch their fuel dollars.

With gasoline and diesel prices continually climbing and setting record highs, improved fuel economy has become a top priority for people and businesses that rely on vehicles and heavy equipment in their daily operations. In addition to providing superior protection and performance, AMSOIL synthetic motor oils, gear lubes, transmission fluids, air filters and fuel additives can have a profound impact on fuel economy.

Synthetic Lubricants
AMSOIL synthetic motor oils, gear lubes and transmission fluids effectively improve fuel efficiency though reduced friction (fluid friction and friction between moving parts), superior thermal and oxidative stability and resistance to volatility.

Fluid Friction
Refined petroleum-based lubricants are composed of irregular molecules of various sizes. As they slip across each other, excess friction is created. The vehicle's engine must burn extra fuel to overcome friction, decreasing fuel economy. AMSOIL synthetic lubricants on the other hand, contain only smooth, uniform molecules that easily slip across each other, reducing internal friction within the lubricant, allowing fuel to be diverted from the task of overcoming friction to reaching the drivetrain, decreasing overall fuel consumption.

In addition, AMSOIL offers lower cold temperature viscosity synthetic motor oils that further reduce fluid friction and increase fuel economy in below-normal operating temperatures without sacrificing protection and performance. AMSOIL Synthetic 5W-40 Premium Diesel Oil, for example, is recommended for diesel applications requiring heavier cold temperature viscosity 15W-40 diesel oils, while AMSOIL 0W-20 Synthetic Motor Oil is recommended for gasoline applications requiring 5W-20 motor oils, and AMSOIL 0W-30 Synthetic Motor Oil is recommended for gasoline applications requiring 5W-30 and 10W-30 motor oils.

Friction Between Moving Parts
Oil viscosity plays a critical role in reducing friction. If viscosity is too high, it contributes to fluid friction, while an oil with a viscosity that is too low cannot adequately maintain a complete, unbroken oil film between engine surfaces. Without this film, excess friction is created between moving parts, increasing wear and fuel consumption. The synthetic construction of AMSOIL synthetic lubricants ensures viscosity remains consistent due to excellent high temperature/high shear properties, maintaining an unbroken oil film between engine parts, reducing friction and decreasing fuel consumption.

Thermal and Oxidative Stability
Some of the chemicals in conventional lubricants break down at temperatures within the normal operating range of many vehicle and equipment components, coating components with varnish, deposits and sludge and leaving the oil thick and difficult to pump. This higher viscosity oil reduces engine and fuel efficiency because components must expend extra energy, and extra fuel, to do their jobs. AMSOIL synthetic lubricants contain no volatile contaminants, making them much more resistant to thermal and oxidative breakdown. Components stay clean, oil viscosity remains constant and fuel efficiency remains high.

Volatilization
Conventional lubricants are also very susceptible to volatility. When the oil's lighter molecules volatize during hot operating conditions, it contributes to further viscosity increase and reductions in fuel economy. Because AMSOIL synthetic lubricants contain uniformly sized molecules, they resist volatilization much better than conventional lubricants, maintain their viscosities and allow more fuel to be used for vehicle propulsion, improving fuel economy.

Calculate the Savings
Industry tests demonstrate an average conservative two to five percent increase in fuel economy by switching to synthetic lubricants, while many AMSOIL customers report even larger gains. According to the most recent data from the Bureau of Transportation Statistics, the average passenger uses 554 gallons of gasoline per year. At a price of $4 per gallon, 554 gallons of gas costs $2,216. A five percent fuel economy improvement would save 27.7 gallons of gasoline and yield $110.80 per year in fuel savings. That's enough to cover the price of a year's supply of AMSOIL synthetic motor oil and Ea Oil Filters, with money left over.

Imagine a fleet of class 8 diesel trucks running an average of 120,000 miles per year at an average 6.5 mpg with diesel fuel at $4.70 a gallon. Using those numbers, the fleet spends $8,676,923.08 on fuel annually. A five percent fuel economy improvement would increase the fleet's fuel mileage to 6.825 mpg and reduce fuel costs to $8,263,736.26. That's a savings of $413,186.82, enough for 87,912 gallons of fuel.

More Fuel Savings
In addition to the fuel savings provided by AMSOIL synthetic lubricants, AMSOIL Ea Air Filters and fuel additives contribute to further fuel efficiency gains.

Ea Air Filters
Incorporating revolutionary nanofiber technology, AMSOIL Ea Air Filters excel in all three areas critical to filtration performance: efficiency, capacity and air flow. The increased air flow contributes to more efficient engine operation, increasing fuel efficiency by allowing the engine to burn less fuel. AMSOIL Ea Air Filters allow more air flow than filters the use cellulose media alone. Cellulose fibers are larger than nanofibers, and have larger spaces between fibers, causing contaminants to load in the depth of the media and plug the air flow path resulting in higher restriction and less capacity. The synthetic nanofibers in Ea Filter media have submicron diameters and small interfiber spaces, which result in more contaminants being captured on the surface of the media and lower restriction. This all leads to improved fuel efficiency.

Fuel Additives

P.I. Performance Improver
As a vehicle's engine accumulates miles, its performance suffers from gasoline fuel-generated deposits that form on the fuel injectors, intake valves and combustion chamber. One of the negative effects caused by these deposits is decreased fuel efficiency. AMSOIL P.I. Performance Improver is the most potent gasoline additive available today. As a concentrated detergent, it is unsurpassed in cleaning combustion chamber, intake valve and fuel injector deposits, restoring peak engine efficiency, fuel economy, power and drivability. Tests show P.I. improves vehicle fuel efficiency by an average of 2.3 percent and up to 5.7 percent.

Diesel Concentrate
Like gasoline engines, diesel engines also become less efficient over time. Fuel injector deposits interrupt spray patterns, causing poor fuel atomization, incomplete combustion, excessive emissions and smoke. Tests prove that AMSOIL Diesel Concentrate cleans dirty injectors, improving fuel economy by up to five percent and restoring horsepower to like new.

Cetane Boost
By raising cetane up to seven points, AMSOIL Cetane Boost effectively improves combustion efficiency for increased power and performance in all diesel engines, increasing fuel efficiency up to 2 percent.

Another AMSOIL First

More than 20 years ago, AMSOIL began using the NOACK volatility test as a comparison tool and measurement of quality. Back then, nearly every oil tested side-by-side with AMSOIL synthetic motor oils failed, and those that passed barely squeaked by. Other oil companies paid no attention to NOACK results until Ford Motor Company made it a requirement for service fill oils, validating what AMSOIL had said all along.


THE NOACK Volatility Test
The NOACK Volatility Test determines the evaporation loss of lubricants in high temperature service. The more motor oils vaporize, the thicker and heavier they become, contributing to poor circulation, reduced fuel economy and increased oil consumption, wear and emissions. AMSOIL Synthetic Motor Oil resists high temperature volatization better than other motor oils. AMSOIL Synthetic Motor Oil maintains peak fuel efficiency and reduces oil consumption and emissions.
