Racing Motor Oil

Few applications are tougher on lubricants than racing. The ability of AMSOIL synthetic lubricants to withstand intense heat, elevated horsepower and massive torque has made us a fixture at all types of racetracks. Our synthetic lubricants have helped teams operating off-road trucks, stock cars, high-powered boats, motorcycles and snowmobiles capture countless checkered flags and season championships. We believe that Racing is Research™, and we use the data collected from racing to tailor the complete AMSOIL product line for even greater levels of performance.

The AMSOIL Offshore Racing Team has claimed many national and world championship titles in several different categories of racing, and AMSOIL DOMINATOR Synthetic Racing Oil has been key to its success. After a full racing season covering 3,000 miles of extreme driving, a teardown of one of the team’s Mercury* 525 EFI V-8 engines revealed clean, virtually wear-free components.

Check out our synthetic racing motor oils - specially formulated to provide superior performance and maximum protection in high-performance and racing applications.

Racing Tips with AMSOIL Maintenance Technician and Racer Justin Madsen

We recently sat down with AMSOIL Maintenance Technician (Buildings and Grounds) Justin Madsen, a championship-winning dirt-track racer, to dig into the racing scene and provide some tips for people interested in getting started. 

What tips do you have for someone interested in getting into racing?

While it is fairly easy to get into racing, I would use caution about jumping in with two feet. There is a learning curve and a lot more goes into racing a car than simply strapping in and smashing the gas. Racing takes time and practice – the more seat time you can get, the better you will become. To get the best deal on a car and spare parts, shop around online and reach out to racers in the class your looking to get into. Don’t forget about a truck and trailer!

What have you learned along the way?

Since I began racing six years ago, I’ve learned advanced vehicle maintenance and auto body tricks. I’ve also learned about track conditions and how to make adjustments to the car to prepare for the changes throughout the night. Although every race is a competition, the respect and sportsmanship we have as racers is so important. We keep our problems on the track and maintain a professional relationship.

What is one thing you wish you had known from the start?

That it takes a whole lot more than just a big engine to win. In fact, I’ve been more successful with an engine that didn’t put out the highest horsepower. I’ve found that good tire work and the proper shocks have helped me more than anything else. 

What modifications have you done to your car?

I have a 1985 Buick Regal with the following:
  • Standard-bore 305 built by Troy’s Shop racing engines
  • Vortec pistons
  • Iskenderian camshaft fueled by a Quardrajet carb that was built and tuned by Performance Specialists
  • Moog springs with Billstein shocks

My transmission is a turbo 350 that was built by AMSOIL racer Darrell Nelson.

Any final thoughts? 

It takes a lot of time, effort and money to keep a car running at its max potential. Having a good crew to help is essential; I am fortunate enough to work with my friends or family, which makes it more enjoyable.
