In engineering, breakthroughs rarely begin with marketing claims. They begin with questions.
Back in 2019, while developing the Banks Ram-Air® Differential Cover system, our engineering team found itself focused on a problem few people had seriously explored: at what temperature does gear oil begin to oxidize inside a rear differential housing?
It was not a casual question. Differential temperatures directly affect lubricant life, component wear, and long-term reliability—especially under heavy towing, high-load, and high-performance conditions. If we were going to engineer a superior differential cover, we needed real data. Not assumptions. Not advertising language. Actual engineering information.
So we started asking lubricant manufacturers.
Most would not share meaningful technical data. Some avoided the question entirely. Others provided vague answers that lacked the depth required for engineering validation.
One company stood apart.
AMSOIL was the first lubricant manufacturer willing to openly share detailed technical information with our engineering team. They understood the question we were asking, and more importantly, they respected why we were asking it. That willingness to engage in a real engineering discussion immediately distinguished them from the rest of the industry.
What began as a single technical conversation evolved into an ongoing relationship.
As development of the Ram-Air Differential Cover continued, we repeatedly turned to AMSOIL for additional data, testing insight, and technical discussion. Every interaction reinforced the same impression: this was a company driven by engineering rather than marketing.
Eventually, that relationship led us to Superior, Wisconsin—home of AMSOIL headquarters.
There, Gale Banks and members of our team toured AMSOIL’s facilities, laboratories, and testing operations firsthand. What we saw changed our perspective.
This was not simply a lubricant company selling synthetic oil. It was a company deeply invested in chemistry, testing, quality control, and long-term product performance. The level of technical rigor, in-house validation, and engineering discipline was immediately apparent.
For Gale Banks, the visit confirmed something important: AMSOIL’s products were not just different—they were superior.
The experience strengthened a relationship that had started with something simple: transparency.
In an industry where technical data is often guarded or diluted into marketing language, AMSOIL chose openness. They shared information when others would not. They treated engineering questions seriously. And over time, they earned our trust.
That trust eventually evolved into a formal partnership.
Today, AMSOIL is the exclusive lubricant partner of Banks.
That decision was not based on sponsorships or branding opportunities. It was based on years of technical interaction, shared engineering values, and firsthand evaluation of how these products are developed and tested.
Performance matters. Data matters. Engineering matters.
And sometimes, the strongest partnerships begin with a single unanswered question.
First-Fill Lubricants for Banks Products
That partnership extends beyond engineering discussions and testing.
Today, select Banks products can be ordered with AMSOIL lubricants included as a factory-recommended first fill at the time of purchase. This allows customers to install their Banks components with the same premium lubricants trusted during development and validation.
Products include:
By offering AMSOIL lubricants directly alongside these products, we help ensure customers receive the proper viscosity, performance specification, and fluid quantity for their application from day one.
It is another example of how the relationship between Banks Power and AMSOIL is built around engineering compatibility and real-world performance—not convenience or branding alone.
AMSOIL Refills for Banks Products
Routine maintenance matters just as much as initial installation.
To simplify service intervals and fluid replacement, AMSOIL also provides dedicated product pages that identify the correct lubricant types and quantities for Banks-equipped systems. Customers can quickly purchase the exact replacement fluids recommended for their Banks oil pan, transmission pan, or differential cover directly through AMSOIL.
