EOA Oil Additive
IMPORTANT: We provide this technical information to you, our distributors, so that you have confidence in
our new EOA product so that you can compete effectively in the marketplace against anyone. We don’t
recommend leaving this informational sheet with a customer, however, it may be useful in a
product presentation.
One of the most important components of any oil additive is it’s composition of EXTREME PRESSURE
ADDITIVES.
Available today in the marketplace are basically three different elements commonly used as active ingredients
in EXTREME PRESSURE ADDITIVES: zinc, sulfur and phosphorous. Let’s take a look at these 3 items and
see how they can affect an oil additive.
SULFUR is effective as an extreme pressure (EP) additive when operating temperatures are around 200° C;
below this temperature and at higher temperatures, the sulfur is an ineffective extreme pressure additive. In
addition, if there is too much sulfur in the formula, it will not burn cleanly in a combustion motor and will
create ash build-up sludge.
PHOSPHOROUS is an excellent EP agent, especially when the maximum dose is “balanced” between a
calcium and detergent package. Phosphorous compounds react with metal sulfides to create a metal phosphate
protective film. This film is formed at a much higher temperature than the sulfur EP agents. When combining
sulfur and phosphorous together in an EP package, the sulfur provides the low temperature extreme pressure
protection and the phosphorous provides a high temperature extreme pressure protection.
ZINC salts are the most common anti-wear additives as they not only are clean burning when combusted
(ashless), but also act as oxidation and corrosion inhibitors. In addition to being an excellent low temperature
EP agent, zinc is also a very effective anti-wear agent and a primary hydraulic oil detergent dispersant. Zinc
additives are effective below 150°C, sulfur is effective from 150-250° C and phosphorous is effective above
200°C. Both the zinc and phosphorous “plate out” and coat the motor to form an effective barrier.
Many companies will load their oil additives in one area for demonstration reasons.
Well•Worth® utilizes a balance of zinc, sulfur and phosphorous to create a motor oil additive that stabilizes
over a wide range of temperatures and is relatively ash-less during combustion.
At this time we haven’t had the opportunity to analyze more than the BG MOA oil additive to make
comparisons against our new EOA product. However, we welcome distributor’s suggestions on which products
they would like to see analyzed in the future.

We did have an independent testing lab analyze BG’s MOA against Well•Worth’s EOA and the following
results and conclusions have been drawn:
The Well•Worth® EOA additive contains a balanced amount of sulfur and almost twice as much active zinc
and phosphorous as the BG MOA additive, thus making EOA a more balanced and cohesive additive package
that covers a broad spectrum of operating temperatures. In order to compensate for the low amounts of zinc and
phosphorous, BG utilizes more than 3 times additional sulfur complexes than the Well•Worth EOA. As we
mentioned above, high concentrations of sulfur will not burn cleanly in a combustion motor and will create an
ash build-up sludge. Because of this build-up MOA must contain a greater percentage of calcium detergents as
well.
Additional problems with any oil additive product using a high sulfur technology for the EP additive results in
excessively high emission tests for sulfated ash and sulfuric acid. Usually these types of products perform well
initially, but the high levels of sulfur create sulfated ash and sulfuric acid build-up at about 3,000 miles. This is
a dangerous situation in today’s tight tolerance, high revving engines. The oil thickens and causes a lack of
lubrication in the system, thereby degrading the life of the system. Lastly, sulfur in engine oils is bad for the
catalytic converter.
In summary, the Well•Worth EOA oil additive product is a balanced, cohesive and complete additive product
that will offer anti-wear effectiveness over a large temperature range, offer outstanding detergency and
guarantee oil stability and complete additive protection for an additional 3,000 miles.
