Anti-Wear Formulation

Racing and high-performance engines are typically modified to deliver maximum horsepower and speed. Their powerful designs create shearing forces that can cause lesser oils to lose viscosity, leaving bearings, pistons and other components vulnerable to wear and failure. DOMINATOR Synthetic Racing Oil’s durable formulation resists viscosity loss due to mechanical shear to maintain a strong protective oil film. It is heavily fortified with zinc and phosphorus anti-wear additives to provide additional protection against scuffing and wear in severe racing conditions (see results below).

piston-crown-and-camshaft

The piston crown contains normal carbon, while the rings remain clean and functional. Note the absence of wear or scuffing on the piston skirt. The camshaft shows little-to-no scoring, bluing or wear after 3,000 miles of high-performance racing.

 

Maximum Horsepower

The excessive friction and heat of racing robs engines of power and longevity. DOMINATOR is formulated with a proprietary friction modifier for maximum horsepower and cooler engine temperatures, promoting improved lap times and longer-lasting components.

  • Formulated specifically for racing & high-performance engines
  • Robust formulation resists viscosity loss
  • Proprietary friction modifier maximizes horsepower & torque
  • Fortified with anti-wear additives for extra protection

Protection From Startup to the Checkered Flag

DOMINATOR provides maximum protection in temperature extremes. Its low pour point offers excellent cold-start protection and provides less drag when the oil has not reached stable operating temperatures. At elevated operating temperatures, it maintains superior film strength. DOMINATOR’s thermally stable synthetic chemistry resists the effects of intense heat common to racing engines to provide reliable protection for the duration of the race.

Commercial Availability

Many oil companies produce specialty racing oils for elite groups and do not offer them to the general public. All AMSOIL synthetic motor oils are already formulated to a higher level of performance than competitors’ oils, and AMSOIL DOMINATOR Synthetic Racing Oil is no exception. It provides maximum performance and superior protection to all racers, regardless of their level of competition.

Ask AMSOIL: Is it OK to use Racing Oil in my Street Car?

redbull racing and amsoil

Motorists who are passionate about engine protection and performance can easily succumb to the following line of reasoning:

1) Racing engines are more severe than my engine.

2) Racing engines use racing oil.

3) Therefore, I should use racing oil in my vehicle for best protection.

It’s true that the average racing engine creates operating conditions more severe than the average passenger car engine. However, that’s not to say that modern engines aren’t tough on oil, too.

Increased heat and stress

The turbocharged, direct-injection engines in modern vehicles generate increased heat and contaminants compared to their predecessors. Motor oil bears the brunt of the added stress. That’s why industry motor-oil specifications keep growing tougher and automakers are increasingly recommending synthetic oils to meet these strict performance specs.

Racing creates tougher operating conditions

Racing, however, is a whole different animal. The powerful, modified engines in racing vehicles produce extreme heat and pressures beyond the capabilities of the average car or truck. A 900-hp Pro 4×4 off-road racing truck can produce engine temperatures of more than 300ºF (149ºC). Engine temperatures in a typical passenger car/light truck fall somewhere between 195ºF and 220ºF (90ºC – 104ºC). The difference is even more striking when you consider that the rate of motor oil oxidation (chemical breakdown) doubles for every 18ºF (10ºC) increase in oil temperature.

The tremendous shearing forces the oil bears as it’s squeezed between the interfaces of the pistons/rings and cam lobes/lifters pose another problem. The pressure can tear apart the molecular structure of the oil, reducing its viscosity and film strength.

Racing oil must be formulated differently to protect these demanding engines. Even so, it doesn’t mean you should order a case of AMSOIL DOMINATOR® Synthetic Racing Oil for your car.

Racing oils are changed more frequently

Why? For starters, racing oils are changed frequently. Most professionals change oil every couple races, if not more frequently. For that reason, racing oils are formulated with a lower total base number (TBN) than passenger car motor oils. TBN is a measure of the oil’s detergency properties and its ability to neutralize acidic byproducts. Oils with longer drain intervals have higher TBNs. AMSOIL Signature Series Synthetic Motor Oil features a TBN of 12.5 to enable its 25,000-mile/one-year drain interval. In contrast, DOMINATOR Synthetic Racing Oil has a TBN of 8 since it should be changed more frequently. As great as it performs on the track, DOMINATOR is not what you want in your engine when you’re driving thousands of miles and several months between oil changes.

Second, you want to use an oil in your daily driver that excels in several performance areas:

  • Wear protection
  • Long oil life
  • Maximum fuel economy
  • Engine cleanliness
  • Corrosion protection
  • Oxidation resistance
  • Easy cold-temp starts

Motor oil additives produce many of these benefits. For example, anti-oxidant additives fight high heat and extend oil service life. Anti-wear additives interact with the metal surfaces of engine parts and guard against metal-to-metal contact. Many additives form layers on metal surfaces. That being the case, they compete for space, so to speak.

Racing oils use different additives

Racing oils are often formulated with a heavy dose of friction modifiers to add lubricity for maximum horsepower and torque. The boosted level of additives meant to increase protection and performance during a race doesn’t leave room in the formulation for additives found in passenger car motor oils that help maximize fuel economy, fight corrosion or improve cold-weather protection.

Achieving the tasks of a street car motor oil requires a finely balanced formulation. Too much or too little performance in one area can negatively affect other areas – and the oil’s overall protection and performance. The list of tasks required of a racing oil, however, is much shorter.

The right tool for the right job is an axiom with which most are familiar. The same holds for motor oil. It’s best to leave racing oil to competition engines and use a properly formulated passenger car motor oil for your daily vehicle.

If you use your street or passenger car on the track it’s most likely still best to use the Signature Series or one of the other passenger car oils (AMO 10W-40 or Z-ROD formulations) over the racing oils due to the needed additives for that sort of operation.
All of these choices are available at the 84th St Omaha AMSOIL location.
