ASK about our bypass kits:

Why change oil every 5000 miles when you can go at least three times longer and 40 times longer using the bypass system. If you spend 30 minutes each time you wait at a quick lube, when you use the AMSOIL bypass you are saving TWENTY hours. That's valuable time. You also save money on oil, filters, wear, add life to your engine, pick-up 2 to 8.5% in mileage and lower engine temperatures.

AMSOIL - used by the top teams of racing, Other brands may fancy up the skin with their logo but that is not what's used under the hood. Experienced factory racing organizations know AMSOIL results in greater dependability.

Customers can't believe the lower temperatures in all aspects including off-shore racing. The added result is the one most important benefit - significantly less failures.
This was told to me first hand from Bobby Unser Senior. When he needs the best he calls Al Amatuzio (AMSOIL) for the answer.

But the core of our customers in San Antonio are average commuters and commercial businesses looking to cut costs in fuel and average vehicle life.

Texans are fans of AMSOIL!! It delivers. It makes their machines really perform and when someone brags about their so called "better" oil, sooner or later the tests come out showing that product was nothing more than a name.. Or what Al call "A Johnny Come Lately!"

Did you know most of the testing AMSOIL publishes all the way back from the early 70's were done right here in San Antonio? At the Southwest Research Institute (SwRI) which has even stretched the limits of many tests beyond proving AMSOIL is really what founder Al Amatuzio set out to accomplish - The Best!


When using AMSOIL, be sure to check out the By-Pass filtration systems.

STOP Changing your OIL!
When using AMSOIL, you may want to consider the By-Pass filtration systems. Change oil at 200,000+ oil intervals. Just change the full flow (EA OIL Filter) yearly and the EABP by-pass unit bi-yearly or up to 60,000 miles and top off. We recommend oil analysis after each cycle of new filters at least to monitor so you have full knowledge of the life and superiority of the AMSOIL product, We have prepaid analysis kits available including shipping costs. We recommend using Oil Analyzers as they specialize in synthetic oil testing and give your fleet the most accurate information to extend oil use and spot conditions accurately.

Now choose the oil you need and the nanofiber oil filter. Both designed and guaranteed for 25,000 miles. Our oil filters use our own specifications plus licensed from Donaldson the same media required by the US ARMY for the Abrams tank. AMSOIL is the only company to offer this technology to automobiles and soon - motorcycles.

Reasons for By-Pass filters

  • Extend Oil Drain Intervals
    • You save money because you are changing your oil less often! You also help reduce America's dependence on foreign oil.
  • Improved oil cooling
    • Your engine will run cooler, which helps to reduce wear on your transportation investment
  • Increased filtration capacity and life
    • Your oil is filtered more effectively and efficiently, thus removing more wear particles and reducing the contaminants that cause damage to your engine. Engine life is extended.
  • Increased fluid system capacity
    • Your engine has more oil available to lubricate, cool and protect your engine, once again extending the life of your engine.
  • Small particle and soot removal efficiency
    • Removes more small particles and soot contaminants that can cause engine wear and premature damage to your engine. Filters particles less than 1 micron in size. You will get more use out of the investment.
  • Decrease disposal costs
    • Reducing the potential harm to our environment and further reducing dependence on foreign oil.
  • Engine efficiency increased
    • This can help you receive better mileage; which of course saves you money!


Save even more with our new (EaA) - absolute efficiency nanofiber air filters guaranteed to last 100,000 miles or 4-years. At one year or 25,000 miles the AMSOIL (Ea) air filter can be cleaned by compressed air or vacuum at the same time as your oil change helping you consolidate maintenance. NO OIL NEEDED! This reduces your air filter costs to about $9 per year rather than buying a new cellulose air filter every 10,000 miles. The new AMSOIL Ea Air filter is OEM Certified for fit and warranty compliance.

All products are produced in the USA.

AMSOIL is known for advanced lubricants - it goes without saying. But it is interesting to know which two product lines are the most advanced in the whole line well beyond anything else available in the market?? Both of these significantly aid the San Antonio, Texas stop & go traffic market.

These two lines are the grease and the Severe Gear differential fluids. Here's an article to help you with your grease selection:

Mark Nyholm - Technical Product Manager - Heavy Duty

How many of you who own a grease gun know how old the grease is inside the gun? I bet most people answered, “I’m not quite sure.” Outside the heavy-duty and off-road industries, applications requiring grease are among the most overlooked when it comes to maintenance. That’s partly because many equipment manufacturers are designing sealed for- life components that require no additional lubrication. Nonetheless, there are applications that still require us to get out the old grease gun.

So, after first checking your owner’s manual to see what needs greasing, your next question is probably, “What grease should I use?” This is a great question because there are lots of different greases on the market. Just like motor oil, grease can be chosen based on the intended application. Applications that operate in or near water or are frequently subjected to moisture, like boat trailers or ATVs, need a grease with exceptional corrosion protection that stays in place to keep out moisture. These greases are likely termed “water-resistant” or something similar, like AMSOIL Synthetic Water-Resistant Grease (GWR). Heavily loaded applications, like dozers or tractors, need grease to prevent wear and corrosion, seal out contaminants and resist impact. Heavy-duty applications require grease with superior adhesive qualities that will stay in place during demanding service. Such products are likely labeled “heavy-duty” or “off-road,” similar to AMSOIL Synthetic Polymeric Off-Road Grease (GPOR).

If you work with heavy-duty equipment or have customers who use it in their businesses, you know the importance of high-quality grease. Although these two application examples might seem obvious, there are hundreds of others that can make people wonder if they are using the right grease. Oftentimes the equipment manufacturer will recommend a particular grease by providing the preferred NLGI grade and thickener system. This can be essential information for selecting the appropriate grease. The NLGI grade is a standard for grease consistency, or hardness. This nine-number scale runs from #000 to #6, with #000 being the thinnest, almost semi-fluid product, and #6 being very solid. By volume, most greases tend to be in the NLGI #0 to #3 range. There are several options because greases are purpose-built for specific performance.

Proper application and maintenance of grease-lubricated parts is essential to equipment performance and longevity. Grease-lubricated parts generally fail for one of the following four reasons:

1. The wrong type of grease was used. To ensure you are choosing the proper grease, be sure you understand specifics of the equipment, its operating environment and the loads or speeds the equipment endures.

2. The new grease is incompatible with the old grease. This typically results in excessive softening caused by the interaction of different thickening systems. This is normally identified by grease dripping or running out of the application. The safest strategy is to not mix greases, although there are published charts indicating which grease thickening systems are compatible.

3. The greased component was contaminated. This can happen in the pre-greasing stage from using a dirty grease-gun tip, not cleaning zerk fittings or using open containers of grease. Grease can also become contaminated from the introduction of water, dirt or chemicals into the lubricant while in the application.

4. Too much or too little grease was applied. Failing to maintain greaserelated parts with adequate amounts of the correct lubricant can result in component problems, equipment downtime and costly repairs. The lack of grease can cause failure, but too much grease is often the primary cause of failure because the excess grease causes high temperatures, which in turn oxidizes the lubricant.

Grease life is affected by heat, mechanical stress and environmental conditions. As greases age, they tend to become dry and brittle and lose their fluid characteristics. Grease should be examined after as little as one year in storage to ensure the base oil has not significantly separated and that the grease has the proper consistency. Now, if you answered, “I’m not quite sure” to my first question, it’s probably time to change out the grease in that gun.


AMSOIL gives you more for your money as it performs these tasks longer.

Clean - suspend contaminants and prevent them from adhering to components. Critical for used vehicles where maintenance do not exist.

Cool moving elements - Reducing friction will reduce the amount of heat that is generated. AMSOIL PAO base stocks are extremely efficient at absorbing heat from the contact surface area and transport it to a location where it can be dissipated.

Prevent contamination (seal) - We rely on the lubricant to act as a dynamic seal in locations such as the piston, piston ring and cylinder contact areas. This minimizes combustion by-products (for example) from contaminating the lubrication system. AMSOIL Synthetic Lubricants and industrial oils excel in Carbon Formation Resistance, Antifoam, Demulsibility and Hydrolytic stability.

Dampen shock - AMSOIL offers more sheer strength. This is AMSOIL's most commented on attribute. Our large vehicle and motorcycle customers frequently comment on noise and vibration reduction.

Prevent corrosion - A quality not inherent in conventional petroleum lubricants. This can be accomplished either by chemically neutralizing the corrosive products or by setting up a barrier between the components and the corrosive material.

Transfer energy - A lubricant may be required to act as an energy transfer median as in the case of hydraulic equipment or valve lifters in an automotive engine. AMSOIL ATF and hydraulic oils add a significant performance boost, last longer and reduce energy needed to accomplish the same task but to heat reduction.

Major Moves for Team AMSOIL


Eli Tomac and Wil Hahn ready to complete in 450 class next season.


The GEICO/AMSOIL/Honda Supercross/ motocross team has an enviable reputation for developing young riders into world champions, while also providing legends like Mike LaRocco and Kevin Windham a place to cement their legacies.


The 2014 season will mark a significant transition in this established philosophy as the team expands its presence to include two 450 class riders, each promoted from within the team’s impressive stable of 250 class riders.


Starting with the 2014 Monster Energy Supercross season-opener in Anaheim, Calif., champion 250 riders Eli Tomac and Wil Hahn will move up to ride AMSOILbacked Honda bikes in the elite 450 class.


Following in Trey Canard and Justin Barcia’s footsteps, Tomac will be the third GEICO/AMSOIL/Honda rider to reach the pinnacle of the sport after joining the team as a fresh-faced amateur. The Cortez, Colo. native was in his early teens when he first caught the eye of team owner Rick Zielfelder. It’s been a partnership that’s produced dozens of race wins and the 2012 Supercross 250 West title.


“As an amateur, GEICO/AMSOIL/Honda was a team you looked up to,” Tomac said. “They always had a great 250 team and legendary guys like Mike LaRocco and Kevin Windham on their 450. What we’re doing now is a step in a new direction. It’s going to be like a whole new program. To be one of the first guys to make it happen is really cool.”


After a breakout season in 2009, Hahn joined the team for the 2010 season. Unfortunately, in his first race with the team, he broke his back during practice and spent the bulk of the next two seasons recovering from various injuries. Despite the setbacks, Hahn’s presence became a valued one on the team and the group’s patience was rewarded this season when he finished on the podium in all nine 250 East races, including two wins, on his way to the title.


“I didn’t start with them as an amateur, but I feel like I did,” Hahn said. “I was around the team a lot when I was younger, hanging out with my brother, Tommy. I’ve always felt love from this team and I’m honored they asked me to ride the 450 for them. They stuck with me during times when a lot of teams would have let me go. They saw something in me, they kept me on and it paid off for both sides.”


Team owner Jeff Majkrzak said expanding to two 450 riders is a big step, but one the team has been working toward for a long time.


“We only wanted to expand to two 450 riders if we could do it the right way,” Majkrzak said. “We wanted to make sure our major partners – GEICO, Honda and AMSOIL – were ready and willing to go on this ride with us. The timing was perfect and we’re excited for the team’s future with Eli and Wil leading the way for our 250 and amateur teams.”


Tomac and Hahn are both excited to make the transition to the top class in familiar surroundings.


“Moving to a 450 is a big enough step as it is,” Tomac said. “I would imagine that the transition would be a lot harder if you’ve got to learn a new motorcycle and a new team. I won’t have to do that. I already know this inside and out. I’m excited to get started.”


“Riding for a factory 450 team is something you dream about as a kid,” Hahn said. “Everyone on the team has a constant drive and determination to win. Everyone works together for that goal.”


The Supercross world will get a preview of the new 450 duo when they take to the track at the October 19 Monster Energy Cup at Sam Boyd Stadium in Las Vegas.

  • Vehicle manufacturers are installing synthetic oil into new vehicles on the production line.
  • Cars & Trucks made before 1995 need oils with more anti-wear additives and better quality detergents.
  • Drivers discovering top quality (real) synthetics do indeed increase fuel mileage.
  • New lubricant trends demanded by industry are developed well before the engine and transmission technologies hit the marketplace. This allows AMSOIL to further develop their product even further while the competition arrives late testing their product after the requirement goes live.
  • New emission systems demand oils, which can take more heat and leave fewer deposits. Currently diesel engine changes have created problems which demand more stable base stocks. We have them and you save more fuel to boot!
  • OEM Automatic Transmission Fluids are limited to light duty use. AMSOIL ATF and Low Viscosity Trans Fluid cuts temperature significantly and delivers more power to the wheels. Our transmission fluids continue to be well ahead of the industry because of AMSOIL's relationship with suppliers.
  • They are demanding better lubrication qualities from the oil to improve fuel economy.
  • Commercial vehicles Require synthetics in transmission and drivetrain parts to retain extended warranties. (And better power transfer).
  • Environmentally we can not go on disposing of the millions of gallons of oil each year that is the bi-product of 3,000 mile oil change intervals - Imagine if everyone changed their oil at say 7,500 miles instead. The used oil disposal problem would be cut by 50%. Yes 50%, not just 1 or 2% - Now consider the impact of a 25,000 and beyond oil change interval.
