~ Seats Rings Fast and Efficiently

When breaking in a motor, the main objective is to seat the rings against the wall of the cylinder. When rings are seated properly, they increase compression, which will result in maximizing horsepower. This will also decrease the consumption of oil and prevents high-temperature gases produced by combustion from getting into the crankcase.

To accomplish this, the oil has to enable the proper amount of “regulated wear” between the ring interface/cylinder wall while still protecting other vital motor components from wear. Inadequate break-in causes peaks to form on the walls of the cylinder, preventing the rings from properly seating. Meanwhile, the deepest valleys cause excess oil to accumulate and burn during ignition, increasing the consumption of oil.

Excessive wear causes glazing of the cylinder when peaks “roll-off” into valleys, stopping oil from accumulating and properly lubricating the wall of the cylinder. The friction-modifier-free solution of AMSOIL Break-In Oil causes the intense peak on cylinder walls that are freshly honed to partly compress.

~ Prevents Wear on Critical Parts

Since new lifters and flat-tappet camshafts have not been broken in yet, to reach the correct stiffness they must be heat-cycled first. These parts are prone to increased wear while in the break-in process since they’re splash-lubricated, as opposed to other sections of the motor that are lubricated by pressure. AMSOIL Break-In Oil provides high amounts of zinc and phosphorus (ZDDP) additives that are intended to provide resistance against wear during this crucial time.

~ Film Strength is Increased

Aftermarket components designed to maximize horsepower and torque are often used in racing and high-performance motors. The added tension will cause the oil film that protects main and rod bearings from dangerous metal-to-metal interaction that causes rupturing. AMSOIL Break-In Oil‘s base stock oils have additional film stability to prevent wear from degrading bearings.

AMSOIL Engine Assembly Lube

Engines that haven’t been fully constructed will sit idle for long periods of time. During this phase, a high-performance engine assembly lube should be added to the parts to provide wear defense, discourage corrosion, and aid in the prevention of deposits forming. It is formulated to dissolve in oil, thus reducing the clogging of oil ports.

~ Strongly Sticks to Components

Since engine construction can take anywhere from a couple of days to several months, utilizing a high-quality engine assembly lube that adheres to components for long periods of time is important. AMSOIL Engine Assembly Lube is made with a high-viscosity base stock oil and a proprietary tackifier to provide a lengthy, tenacious grip.

~ Extraordinary Protection Against Wear

Engines run with hardly any oil pressure at initial startup, putting camshaft lobes, rocker arms, bearings, lifters, and other vital parts at risk of failure and wear. AMSOIL Engine Assembly Lube provides high amounts of anti-wear additives for adequate protection, in addition to preventing wear by tenaciously sticking to components.

~ Helps Prevent Corrosion and Rust

A partially built engine can remain in storage for extended periods of time, causing oxygen and moisture to develop rust on metal surfaces that are exposed. AMSOIL Assembly Lube includes corrosion and rust inhibiting additives, which preserve engine parts while the engine is not in use.

~ Prevents Port Clogging by Dissolving in Oil

Assembly lubes that are grease-based will raise the risk of clogged oil ports if not fully ingested during the initial start, possibly resulting in motor failure. Engine Assembly Lube by AMSOIL is specifically formulated to dissolve in oil, thus maintaining clean oil ports and preventing the formation of deposits in the oil pain and under valve covers.

AMSOIL DOMINATOR® Octane Boost

DOMINATOR® Octane Boost
AMSOIL DOMINATOR® Octane Boost

Previously, engines were designed to run on leaded fuel. As a result, vintage and collector cars often necessitate the use of a lead replacement in order to conserve the components that were engineered for the gasoline of yesteryear.

AMSOIL DOMINATOR® Octane Boost works well as a lead replacement in older engines. It boosts octane by up to four points, which helps minimize engine knock and boost combustion while also making fuel burn cleaner.

AMSOIL DOMINATOR® Octane Boost (AOB) boosts engine reaction and power in both two- and four-stroke gasoline-powered engines by boosting octane by up to four numbers. Just one application eliminates motor knock, increases ignition, and aids in cleaner fuel combustion.

DOMINATOR® Octane Boost is the octane boost that is suggested for both high-performance racing and off-road and racing applications. Most consumers find that one 12-ounce bottle of DOMINATOR® Octane Boost for every 15 gallons of fuel offers the best performance improvement. DOMINATOR® Octane Boost is also an outstanding lead replacement at the same treat levels in collector cars, older off-road engines, and leisure vehicles.

~ What’s “engine knock” and why is it important?

The term “knock” refers to the unregulated and explosive burning of a hydrocarbon fuel, such as gasoline, in the combustion chamber. It makes a banging or pinging sound, drains the engine’s power, and can cause significant motor damage if left untreated. The octane amount of a fuel determines its propensity to knock. Lower numbers indicate greater knock proclivity, whereas higher numbers indicate greater knock power. Knock can be removed by using the proper octane number. Luckily, this is what AMSOIL DOMINATOR® Octane Boost was designed to prevent.

AMSOIL Engine Fogging Oil

Any engine that would be stored or inactive for an extended period of time should be handled with Engine Fogging Oil first. Applying a shot of lubricant to the cylinders saves them from rust, deterioration, and damaging dry starts the next year as you start up your hot rod or vintage vehicle.

Water vapor can condensate inside the engine during times of inactivity as a result of variations in ambient temperatures.  Surface corrosion occurs on piston rings, cylinder liners, anti-friction bearings, and iron/steel contact surfaces on rotational seals as this condensate comes into close contact with iron and steel parts. Long stretches of storage time can also cause cylinders to get dry, which can result in irreversible damage until the vehicle is removed from storage and dry-started.

Most two- and four-stroke engine oils are designed to have an attraction to engine part surfaces, serving as a shield to prevent condensate from touching and corroding engine components. However, the efficacy of motor oil in this region deteriorates with time.

Engine Fogging Oil (FOG) has excellent film retention, which protects against rust and dry starts over time, maximizing engine life and lowering maintenance costs. Its aerosol spray formulation allows for neat and straightforward applications while covering more components and providing total oil distribution, which is particularly useful in horizontal cylinder orientation applications.
