AMSOIL and Racing

AMSOIL Absolute Efficiency Oil Filter Many oil companies produce specialty racing oils for elite groups and do not offer them to the general public. For instance, several popular oil manufacturers produce racing oils offered only to NASCAR racers. AMSOIL receives inquiries as to why the company does not offer "special," higher-quality or NASCAR oils.

However, all AMSOIL synthetic motor oils are already formulated to a higher level than competitors' oils, and AMSOIL Dominator Synthetic Racing Oils are no exception. They provide maximum performance and superior protection to all racers, regardless of their level of competition. The same AMSOIL Dominator Synthetic Racing Oils that are used in the engines of AMSOIL corporately-sponsored racers such as Scott Douglas and Brady Smith are available to everyone.

Every professional race car in the world uses synthetics, and most of them have been using AMSOIL for decades. Many have a lot of money at stake with their "big oil" sponsors, who want you to believe that what is advertised on the car is what's running in the engine.

Indy Car racing legend Bobby Unser spoke at the AMSOIL 30th Anniversary Convention. Unser is a 3-time Indy 500 winner, has 25 overall Indy Car wins and is a 13-time Pikes Peak Hill Climb winner. He told the audience how his race car differentials could not survive more than one race up Pikes Peak without needing to be rebuilt, until he started using AMSOIL lubricants. This experience in Bobby's early years of racing began his long relationship with AMSOIL synthetic motor oil and lubricants in all his race cars. Bobby went on to say that "AMSOIL is the Best Synthetic Lubricant made, the Standard to which all others are judged." Hear it from Bobby himself in the video below.

Extended Drain Intervals mean Less Waste Oil, Less Pollution, a Cleaner Environment

"Improperly disposed used oil," according to the Environmental Protection Agency, "is the largest single source of oil pollution fouling our nation's waters. According to the American Petroleum Institute, it amounts to "up to 200 million gallons of used motor oil... dumped every year down sewers, drains or in the ground." API reminds us, too, that, "A single quart of oil can foul thousands of gallons of water."... Continue reading this article

Where to Find AMSOIL Locally
The Original, 1972
There was a time when people weren't sure what synthetic oil really was. AMSOIL, the company that brought this new technology to the passenger car market in 1972, didn't have the deep pockets of the major oil companies, and this new kind of oil was something of a mystery to car owners, and seemed expensive. Conventional oil had become a commodity and was used as a loss leader by the nation's auto parts outlets. One thing for certain, once you "got it" you didn't go back.

Twenty years later, things began to change. Due in part to pressures to improve fuel economy, and in part due to the increased performance demands of internal combustion engines, most of the major oil companies followed the AMSOIL lead and began to add synthetic oil to their product lineups. What they didn't have, however, was the two decades experience in formulating premium synthetic lubricants for any and every kind of engine application, and the lessons learned from billions of miles service by real life customers.

In the beginning people asked what it was. Today, people understand the value of AMSOIL synthetic oils and and fluids, and the question now asked is, "Where can I find it?"

AMSOIL is available at our online store at, but you can also use our Online Locator to find an AMSOIL Dealer or retail outlet in your own home town.

-Help Us Find the Stolen Vintage Motorcycles
A couple weeks back we did a blog story here about the coast-to-coast motorcycle adventure called The Cannonball Run, a long-distance marathon on vintage motorcycles. American Iron editor Buzz Kanter and three team mates were making the run again this year, and AMSOIL was helping keep their bikes lubed for the duration.

Yesterday news came out that the motorcycles of four other riders were stolen, a heartbreaking way to be taken out of an event like this which ought to be a joyous, even if grueling, group experience.

We're posting the story here in the hopes that if you know people who know people we want to help get the word out to you. The four vintage Harley-Davidsons were stolen from the Hotel Murano in Tacoma, Washington. There's a $20,000 reward being offered by Team Carson Classic Motors.

The news broke here at the Cycle World website where you can read full details on the types of motorcycles that were taken and what you can do to help apprehend the criminals.

-Why is there a time limit – in addition to a mileage limit – on motor oil?
Most vehicles carry a motor oil service-life recommendation that includes a duration of time in addition to a mileage distance. For example, your vehicle might call for an oil change every 5,000 miles or six months. It’s obvious that thousands of miles of driving will take its toll on engine oil, but less obvious is the role time plays in breaking down motor oil.

Even when you’re not driving, chemical changes take place within motor oil that lead to degradation and the need for an oil change. Oxidation is a prime culprit. The interaction between oxygen molecules and motor oil molecules naturally leads to chemical breakdown. Just as oxygen causes a cut apple to brown or exposed metal to rust, it breaks down base oils and reduces motor oil’s effectiveness. Although synthetic base-oil molecules are naturally much more resistant to oxidation than conventional base-oil molecules, they eventually succumb to oxidation’s attack. Oxidation can lead to increased oil viscosity, which negatively affects energy efficiency. It also causes the formation of harmful deposits and sludge.

Your vehicles are also subjected to temperature swings, even when not in use. Temperature swings cause condensation to form inside the engine, leading to water contamination. Not driving for extended periods – or taking short trips that don’t allow the engine to fully warm up – allows water to remain in the oil rather than evaporating and exiting through the tailpipe. Water contributes to engine corrosion.

When you do drive, contaminants form as natural byproducts of combustion. Acids lead to sludge formation and corrosion, and those acids and other contaminants continue to affect chemical changes in the oil, even while not driving.

Even though all motor oils have to eventually be changed regardless of mileage, high-quality synthetic oils – like AMSOIL synthetic motor oils – allow you to go longer between oil changes for maximum convenience and cost savings. Premium synthetic motor oils also offer increased resistance to oxidation for excellent engine protection, making them the right choice even if you don’t practice extended drain intervals. AMSOIL synthetic motor oils are formulated with advanced chemicals that resist breakdown, disperse contaminants and clean internal parts to continue delivering outstanding performance and protection long after conventional oils have to be changed.

-National Truck Driver Appreciation Week: Keep On Truckin'
National Truck Driver Appreciation Week, September 14-20, is when America takes the time to honor all professional truck drivers for their hard work and commitment in tackling one of our economy’s most demanding and important jobs. There are more than 3.2 million professional men and women who not only deliver our goods safely, securely and on time, they also keep our highways safe.

Here's an interesting infographic with a variety of interesting facts about American truckers. Some of the things you might learn that you didn't know include the number of commercial trucks in the U.S., the average age of today's truckers, how many miles per year the average trucker drives, the five top movies for truck lovers, and comparisons between cars and trucks in terms of engine size, horsepower and miles driven. And much more!

In short, there's probably a lot you don't know about the trucking industry.

Americans are more dependent on the trucking industry than most Americans are aware of. This article is very instructive in with regards to what would happen if all trucking were to cease today. Not only are our food and medical supplies dependent on trucking, our stores would eventually be out of stock and our gas stations out of fuel. Eventually, in much of the country our clean water supplies would be threatened and life as we know it will no longer be taken for granted.

The power to deliver all these goods comes from engines and drivetrains which require lubrication to operate properly. Just as we take all this shipping activity for granted, a lot of people (including truckers) take their lubricants for granted and do not realize that a premium synthetic oil can actually make a difference in fuel economy and bottom line savings. In one diesel fleet fuel economy study, AMSOIL synthetic drivetrain lubricants were shown to increase fuel economy in short-to-medium haul trucking applications by 6.54 percent.  Another EPA Federal Test Procedure demonstrated how switching to AMSOIL Premium API CJ-4 5W-40 Synthetic Diesel Oil generated fuel economy improvements of 1.25 to 3.10% compared to conventional 15W-40 diesel oil.

The trucking industry accounts for 12.8% of all fuel purchased in the United States. Could this be reduced a little if we switched all these fleets to AMSOIL?

For what it's worth... we're grateful for our nation's truckers, male and female, young and old. Keep on truckin'.

-Sled Rehab Provides a Thrill for Three at Haydays
An exciting new look for first place winner Traci Leonard's Arctic Cat M6.
It may not feel like winter at this moment, but the official kick-off for snowmobile enthusiasts already took place several weeks ago in North Branch, Minnesota. Hay Days, an annual event sponsored by the Sno Barons Snowmobile Club, is an annual acknowledgement that summer's days are numbered, for better or for worse. For winter sports enthusiasts like skiers and snowmobilers, it's for better.

One of the events in this year's Hay Days carnival was the AMSOIL Sled Rehab competition. By means of social media AMSOIL offered snowmobile owners a chance to take their old sleds and have them refurbished for the 21st century. If you had a sled, 1996 or newer -- mechanically sound and in good running condition -- that could use a makeover, you were invited to upload a photo of your sled and tell your story. Three sleds were ultimately chosen for makeovers which would then take place at Hay Days.

The snowmobile makeovers included a custom sled wrap from Action Graphics plus C&A Pro Skis, hand guards, clutch kits and premium AMSOIL products for snowmobiles. It was a pretty sweet deal and the winners appreciated the attention they garnered for their machines. Other sponsors included ISOC, Scheuring Speed Sports, Sled Head 24/7, Straightline Performance and Woody's.

Josh Bretzman: '06 Sno Pro 440 

First place winner Traci Leonard moved to Michigan's Upper Peninsula a year ago primarily for her love of snowmobiling. She's always loved to ride, but even moreso now that her 2005 Arctic Cat M6 has been rehabbed. When she learned that she was winner of the AMSOIL Sled Rehab she said,
"OMG I am so excited!! This has seriously been like the best week of my life."

You can see the end result at the top of this page, and what she used to ride below.

Before photo of Traci's basic black Cat. It's now a whole new machine.
Meantime, we're just about two months away from the Duluth Nationals snocross races that initiates a new snowmobile racing season. We'll see you on the mountain.
