Dominator Synthetic Racing Oil 

Powerful New Product Line of Racing Oil wholesale pricing

AMSOIL is pleased to introduce a new series of Dominator Synthetic 5W-20, 10W-30 and 15W-50 Synthetic Racing Oil. The three new premium synthetic racing oils are specially formulated to withstand the rigors of high-performance and racing applications.

Racing and high-performance engines subject motor oil to elevated RPM, high temperatures and shock-loading. AMSOIL Dominator Synthetic Racing Oils were developed to address these extreme conditions and provide high-quality AMSOIL performance and protection for a variety of racing applications. All three Dominator oils feature the same additive package, providing maximum durability in multiple viscosities. Their shear-stable formulation was engineered to provide maximum horsepower without sacrificing engine protection. Dominator Racing Oils provide straight-grade protection in a multi-grade formulation.

Q: Synthetic motor oil is not good with flat tappet cams!!!

This is by far one of the biggest myths out there.

Sulfur in motor oil actually acts as a contaminant that promotes the formation of sludge and other by-products of lubricant break-down. It is true that PAO based synthetics contain no sulfur because they are formulated from pure chemicals rather than refined from crude oil. Conventional motor oils do contain trace amounts of sulfur; the portions that cannot be refined out. I'm sure what you are referring to is Zinc and Phosphorous which is an important component when running flat tappet camshafts. 

It could also depend on what type of synthetic oil you are referring to. If it is an API (SM) rated synthetic motor oil, then you would have reduced levels of Zinc and Phosphorous, and this would indeed be a bad choice with a flat tappet camshaft.

Below is a direct quote from an Amsoil Technical Service Bulletin. 

FLAT TAPPET CAMSHAFTS 

Issues: 
Engine oils contain anti-wear additives and the most common anti-wear chemistry is zinc dialkyldithiophosphate (ZnDDP), which contains a combination of zinc and phosphorus. In 2005, in an effort to guarantee catalytic converter performance in new vehicles, the American Petroleum Institute (API) and International Lubricants Standards Approval Committee (ILSAC) instituted API SM and IL-SAC GF-4 quality standards which reduced the maximum limit for phosphorus to 0.085% and 0.080% respectively. Both API SM and ILSAC GF-4 specifications also contain a minimum phosphorus content of .065% and .060%. 

Previously, API SL/ILSAC GF-3 oils were restricted to 0.10% phosphorus level, so a concern arose that oils containing lower levels of zinc/phosphorus could provide insufficient protection in high pressure areas of flat tappets and camshaft lobes found in many older cars and high-performance engines.

Technical Discussion
Proper assembly lubes and oil additives should be used during the break-in phase for all new or rebuilt engines with flat tappets. These additives provide the extra protection required at the point of contact during break-in to help the flat tappet face to properly mate with the cam lobe. Once the break-in phase is completed, these additives should not be used because of other engine life issues created by long term use of these materials. AMSOIL does not provide break-in assembly lubricants, but one of the common products is GM, E.O.S., which is an assembly lubricant and is not, as stated by GM, an engine oil additive. AMSOIL does not recommend using any engine oil additives with AMSOIL engine lubricants.

High-performance modified engines benefit from oils with superior film strength and anti-wear properties. The flat tappet/camshaft lobe interface is the one area in an engine that has extreme contact load. This load increases significantly where non-stock, high-pressure valve springs are employed so the use of properly formulated engine lubricants is extremely important to reduce wear and extend flat tappet/camshaft life. In these applications, 

AMSOIL recommends motor oils containing high levels of zinc/phosphorus for superior protection.

Dominator 2 cycle for Boats, snowmobiles, Motorcycles

Product Application
DOMINATOR is recommended for use in high performance stock or modified two-cycle motors, including air or liquid cooled snowmobiles, personal watercraft, motorcycles (Moto X), ATVs, go-carts and outboard motors*. Good for use with coated or non-coated pistons, high-octane racing fuels and exhaust power valves. Compatible with most other two-cycle oils, however, mixing oils should be minimized.

Use at 50:1 pre-mix ratios (2.6 oz. oil per U.S. gallon of gas) or as injection oil where JASO FC or API TC oils are specified. Not suitable for use with alcohol or nitro-methane fuels.

Product Description
DOMINATOR, an AMSOIL exclusive formulation, lubricates and protects high performance two-cycle motors, both on and off the track. High performance motors, particularly those that are modified, operate hotter and at higher RPMs than recreational motors, and they need good oil for peak performance. DOMINATOR is engineered for racing. It has the right film strength and clean burning properties for “on the edge” operation.

• Provides excellent film strength for high heat, high RPM motors
• Reduces friction for maximum power
• Recommended for use with coated or non-coated racing pistons
• Recommended for use with exhaust power valves
• Recommended for use with high octane racing gas
• Burns clean; Prevents ring sticking and plug fouling
• Provides excellent protection at 50:1 pre-mix or in injection system

Super Film Strength
High performance two-cycle motors have high compression ratios, which significantly increase combustion chamber heat and crankshaft bearing pressures. Hot combustion processes quickly burn off and evaporate light oils and cause rapid piston expansion, decreasing piston-to-cylinder wall clearances. This promotes piston scuffing and possible seizure. And increased pressure on crankshaft bearings promotes metal-to-metal contact, wear and pitting.

High heat and pressures require tough oil with better film strength and more lubricity. DOMINATOR, constructed with AMSOIL heavy synthetic oil, handles high heat better than mineral oils and provides improved film strength and lubricity. DOMINATOR reduces friction and provides an extra measure of protection against piston scuffing and crankshaft bearing wear.

Clean Burning
High combustion processes require the proper additives and oils to control deposits. DOMINATOR contains strong, high temperature detergent additives and highly pure AMSOIL synthetic oil. It prevents deposits that cause ring sticking, plug fouling and exhaust port blocking. DOMINATOR is an optimized product for severe service.

 

Amsoil Break In Motor Oil SAE 30

Break-In Oil (SAE 30) - BRK Designed for High-Performance and Racing Engines See Pricing Information / How to order Package sizes include: 1-Quart Bottle 1-Quart Bottles (case of 12)

AMSOIL Break-In Oil is an SAE 30 viscosity grade oil formulated without friction modifiers to allow for quick and efficient piston ring seating in new and rebuilt high-performance and racing engines. It contains zinc and phosphorus anti-wear additives to protect cam lobes, lifters and rockers during the critical break-in period when wear rates are highest, while its increased film strength protects rod and main bearings from damage. AMSOIL Break-In Oil is designed to increase compression, horsepower and torque for maximum engine performance. Quickly Seats Rings The primary goal during engine break-in is to seat the rings against the cylinder wall. Properly seated rings increase compression, resulting in maximum horsepower; they reduce oil consumption and prevent hot combustion gases from entering the crankcase. To achieve this, however, the oil must allow the correct level of “controlled wear” to occur between the cylinder wall/ring interface while maintaining wear protection on other critical engine parts. Insufficient break-in leaves behind peaks on the cylinder wall that prevent the rings from seating. The deeper valleys, meanwhile, allow excess oil to collect and burn during combustion, increasing oil consumption. Too much wear results in cylinder glazing due to peaks “rolling over” into the valleys and preventing oil from collecting and adequately lubricating the cylinder wall. AMSOIL Break-In Oil’s friction-modifier-free formula allows the sharp peaks on newly honed cylinder walls (fig. 1) to partially flatten. The result produces more surface area for rings to seat against, allowing formation of a dynamic seal that increases compression, horsepower and torque (fig. 2). Protects Critical Parts from Wear New flat-tappet camshafts and lifters are not seasoned or broken in and must be heat-cycled to achieve proper hardness. During the break-in period, these components are susceptible to accelerated wear because they are splash-lubricated, unlike other areas of the engine that are pressure lubricated. AMSOIL Break-In Oil contains high levels of zinc and phosphorus (ZDDP) additives designed to provide the anti-wear protection required during this critical period. Increased Film Strength High-performance and racing engines often use aftermarket parts designed to increase torque and horsepower. The added stress can rupture the oil film responsible for preventing harmful metal-to-metal contact on rod and main bearings. The base oils in AMSOIL Break-In Oil provide increased film strength to protect bearings from wear. APPLICATIONS AMSOIL Break-In Oil is designed to effectively break in high-performance and racing engines requiring SAE 30 oil, helping maximize compression, horsepower and torque. RECOMMENDATIONS The engine builder’s or manufacturer’s break-in recommendations should be followed if available. Break-in period should not exceed 1,000 miles. When the rings fail to seat, the exhaust ports will have a large area of oil residue (Fig. 3). As the rings begin this process, less oil is passed and the oil residue area begins to shrink (Fig. 4). When the rings are fully seated and have formed a tight seal against the cylinder walls, no oil residue will be evident. Other common methods to determine if rings have seated include performing a leak-down test or horsepower measurements over time. Break-in duration will vary between engines. Afterwards, drain and fill the engine with an AMSOIL high-performance synthetic oil that meets builder or manufacturer specifications.

Boiling Points
As the brake system heats up, brake fluids with low boiling points begin to vaporize. The brake pedal must travel further to apply the same amount of force on the brakes, causing a spongy feeling. If enough of the brake fluid vaporizes, brake system failure may occur. Brake fluid boiling points are measured on two separate scales:

• Dry equilibrium reflux boiling point (ERBP) - the boiling point of new, freshly-opened, unused fluid. 
• Wet ERBP - the boiling point of a brake fluid after it has absorbed three percent water. 

The minimum dry ERBP for DOT 3 brake fluid is no less than 205°C (401°F), and the minimum wet ERBP is 140°C (284°F). That might not seem very high, but in most brake systems the fluid in the caliper won’t reach that temperature unless the brakes are abused. It only takes four percent water contamination to bring a DOT 3 fluid’s boiling point down to the federal limit.

AMSOIL Series 500 High-Performance DOT 3 Brake Fluid is formulated with the best zinc-based anti-corrosion additives and pH stabilizers. It is designed for high-temperature stability, yet flows easily at low temperatures. AMSOIL Series 500 High-Performance DOT 3 Brake Fluid's superior additive package provides good lubrication throughout the system and can raise boiling points to more than 232°C (450°F). It keeps water in suspension, slowing its effects on the brake system. AMSOIL Brake Fluids have high boiling temperatures, ensuring maximum life and reliable braking power, even in extreme conditions. AMSOIL Series 500 High-Performance DOT 3 Brake Fluid has a dry ERBP of 274°C (525°F) and wet ERBP of 156°C (313°F). AMSOIL Series 600 DOT 4 Racing Brake Fluid has a dry ERBP of 304°C (580°F) and wet ERBP of 210°C (410°F).

Compressibility
When a fluid is non-compressible it means it won’t compress into a smaller volume when pressure is applied. In a brake system, fluid pressure is multiplied by the master cylinder and can reach more than 1,000 pounds per square inch (psi) in the lines. Like any other hydraulic fluid, brake fluid must be non-compressible at the expected pressures to transmit force from one end of the system to the other while simultaneously lubricating the pistons and rubber parts as they move through their bores. If the fluid were to compress, all braking power would be lost. AMSOIL Series 500 High-Performance DOT 3 Brake Fluid remains non-compressible, even at the highest pressures generated in automotive brake systems. AMSOIL Brake Fluid provides superior stopping ability under the most demanding conditions.

Brake Fluid Maintenance
Brake fluids fail either because they boil or because they cease to provide adequate lubrication and corrosion protection. Both reasons for failure are the result of contamination, usually by water or petroleum products.

DOT 3 and DOT 4 polyglycol ether-based brake fluids are hygroscopic, which means they absorb water easily and hold it in suspension, similar to antifreeze. In most climates, moisture seeps into the brake system continuously through the various seals and microscopic pores of the flexible brake lines. This seepage can accelerate as a vehicle ages and there’s almost no limit to how much water the fluid can absorb. By the time brake fluid has been in the system for three years, it can easily reach its wet boiling point. Because this happens gradually, most drivers won’t discover the reduced braking ability until it’s too late.

Many owner’s manuals recommend changing brake fluid every 24 months to remove moisture. Approximately half of all cars and light trucks in the U.S. over 10 years old have never had the brake fluid changed. In addition, powersports applications such as motorcycles, ATVs and UTVs require routine brake fluid changes as well.

• Dry equilibrium reflux boiling point (ERBP) - the boiling point of new, freshly-opened, unused fluid. 
• Wet ERBP - the boiling point of a brake fluid after it has absorbed three percent water. 

The minimum dry ERBP for DOT 4 brake fluid is 230°C (446°F), while the minimum wet ERBP is 155°C (311°F). Their higher boiling points make DOT 4 fluids appropriate for high-performance cars and motorcycles and for vehicles used for towing or in mountainous regions.

In a brake system, fluid pressure is multiplied by the master cylinder and can reach more than 1,000 pounds per square inch (psi) in the lines. Like any other hydraulic fluid, brake fluid must be non-compressible at the expected pressures to transmit force from one end of the system to the other while simultaneously lubricating the pistons and rubber parts as they move through their bores. If the fluid were to compress, all braking power would be lost. AMSOIL Series 600 DOT 4 Racing Brake Fluid remains non-compressible, even at the highest pressures generated in automotive brake systems. AMSOIL Brake Fluid provides superior stopping ability under the most demanding conditions.

Brake Fluid Maintenance
Brake fluids fail either because they boil or because they cease to provide adequate lubrication and corrosion protection. Both reasons for failure are the result of contamination, usually by water or petroleum products.

DOT 3 and DOT 4 polyglycol ether-based brake fluids are hygroscopic, which means they absorb water easily and hold it in suspension, similar to antifreeze. In most climates, moisture seeps into the brake system continuously through the various seals and microscopic pores of the flexible brake lines. This seepage can accelerate as a vehicle ages and there’s almost no limit to how much water the fluid can absorb. By the time brake fluid has been in the system for three years, it can easily reach its wet boiling point. Because this happens gradually, most drivers won’t discover the reduced braking ability until it’s too late.

Many owner’s manuals recommend changing brake fluid every 24 months to remove moisture. Approximately half of all cars and light trucks in the U.S. over 10 years old have never had the brake fluid changed. In addition, powersports applications such as motorcycles, ATVs and UTVs require routine brake fluid changes as well.
