AMSOIL Lab Ensures Maximum Quality Control

Since its inception in 1972, AMSOIL INC. has followed one guiding principle: manufacture products that "exceed customer expectations."

AMSOIL products are tested against the most rigorous standards of the American Society for Testing and Materials (ASTM) International, one of the largest voluntary standards development organizations in the world for technical standards for materials, products, systems and services. ASTM standards are the benchmark for motor oil and lubricant companies.

AMSOIL quality standards make the AMSOIL laboratory critical to the company. The lab moved to the AMSOIL Center in January 2008, where it was expanded to 3.100 square feet, and increase of about 35 percent over its original location in the old AMSOIL Distribution Center.

"The lab was relocated into a well-laid-out space that increases the efficiency of our monitoring AMSOIL materials from delivery by rail and truck to finished products," said Vice President of Operations Scott Davis. "It's an impressive laboratory. When vendors and customers see it, it's a 'wow' factor; when we see it, it's a confidence factor. The layout and design improve processing and efficiency."

Chemists Use ASTM Standard Test Methods

"We follow the testing protocol as it is written for each ASTM standard test method," said Dave Leitten, laboratory director. Test methods prescribed in ASTM standards manuals are used internationally to evaluate the properties of lubricants, oils, fuels and solvents. That means, "other testing laboratories follow the exact same procedures when they run ASTM Standards Test Methods," Leitten said.

Quality Control Measures

Raw materials arriving at the AMSOIL Center in Superior, Wisconsin are tested prior to acceptance of the delivery to ensure they meet AMSOIL quality parameters. Samples are taken directly from the tankers to the lab. Only after the lab reports the raw materials meet quality standards are they sent to the olding tanks, from which they are then blended and bottled.

"We calibrate our equipment on a regular basis to ensure out test results are accurate," Leitten said. "In terms of product quality control, we test our products in three stages. Stage one involves testing all of the raw materials that go into out products."

"Stage two involves testing of the finished blends. Stage three involves testing a production line sample of product going into bottles, pails, drums and totes. We use the same ASTM test methods used in competitive product testing in our day-to-day laboratory quality control testing."

In stages one and two, raw materials and finished are tested against the specifications provided by each material manufacturer. They also must meet specific AMSOIL product specifications for finished goods. "The specifications for our finished goods are based on industry specifications," Leitten said. "We tend to tighten up the finished goods specification ranges so that the variability of the products we manufacture is minimal."

Those specifications usually have an acceptable minimum and maximum range for various attributes. "As an example, a base oil could have an acceptable range for kinematic viscosity at 100 degrees C of 5 centistokes (cSt) (minimum) to 5.4 cSt (maximum)," Leitten said. "We would test this material using ASTM D-445 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids and compare our tested value with the acceptable range and accept or reject the material or blend based on the results." Kinematic viscosity is the measure of a fluid's resistance to flow under gravity at a specific temperature.

Innovative, Superior Products

"We strive to bring innovative products of the highest quality to our customers," Leitten said. "Our corporate policy is to provide products with exceptional performance that exceed customer expectations. We continually test competitor products to benchmark our performance versus other players in the lubricant industry. This testing is expensive and very time-consuming, but it is vital to ensuring our products are the very best our industry has to offer."

Published Results Prove Product Quality

"We often publish the results of our competitor testing as proof of our product quality." Leitten said. "Formulating is a balancing act. Changing the attributes of a product in one area may negatively affect the properties in another. As an example, adding corrosion inhibitors to a lubricant may detract from its wear performance. The key to creating superior products is to balance all the performance areas to create a well rounded lubricant. Our products are near the top in all critical areas of performance and, more often than not, they're at the very top."

Premium AMSOIL Synthetic Motor Oils offer the longest drain intervals on the market, unsurpassed protection and performance that effectively extends equipment life and improved fuel economy, saving customers money at the pump and reducing the nation's dependence on foreign oil.


"AMSOIL INC. warrants that the use of its lubricants will not cause mechanical damage to any mechanically sound equipment when AMSOIL INC. products are used in full compliance with the company's recommendations and instructions."


FULL WARRANTY


AMSOIL synthetic motor oils are formulated to surpass engine test specifications, offering protection far greater than competing motor oils for extended drain intervals. Most synthetic oil manufacturers make no claim to extended drain intervals, deferring to the maintenance schedule provided by the vehicle manufacturer. With its unparalleled oil and warranty program, AMSOIL offers consumers unprecedented protection and economics.


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.

AMSOIL Now An ISO Certified Manufacturer
AMSOIL recently received ISO 9001:2000 certification of our Quality Management System (QMS). NSF International Strategic Registrations is the registrar that has verified our QMS meets the requirements of the ISO 9001:2000 standard, the most widely utilized quality standard throughout the world for quality management systems. ISO standards are used by over 300,000 companies worldwide setting rigorous standards for businesses, government and industry.

ISO 9001:2000 is applicable to any manufacturing and service organization providing a framework for system development that focuses on the customer, quality system performance and ongoing improvement. AMSOIL received ISO 9001:2000 registration under the scope: synthetic lubricants blending, packaging, and other fulfillment directly associated with lubricant product.

The ISO certification puts AMSOIL in line with some of the most efficient companies in the world. It is further assurance that the products and services AMSOIL provides will continue to maintain the high level of quality the company always demanded.
