I've been using adding 3-4 oz of EOS to my oil change of Valvoline Racing oil
Both contains ZDDP for the hydralic tappet cams
Richard Clark,long time associate of Dennis Kirban has come up w/the product as a per serving w/each oil change,here's the following info:
IMPORTANT NEWS THAT WILL INTEREST EVERY TURBO OWNER
We are proud to be introducing a brand new product
of interest to every Turbo Buick owner...
ZDDPlus
Richard Clark will be speaking on this important
subject at the Sunday Night Reunion banquet. He has also been
gracious enough to donate one 2-ounce bottle of ZDDP
concentrate to every adult attending the Sunday night
Reunion Banquet. As you can imagine, the potential of this
product is enormous and you are reading about it here
first. Plus, as an Inner Circle member, you are getting
a special introductory price! We recommend you tell your
friends and you can post this information on any of the
various forums. Currently, we are the main
distributor to the performance car market.
To learn more about ZDDP, simply go on the
internet. Keep in mind, some of the information
concerning solutions will not be correct. For example:
GM no longer sells EOS. It may also be true that
certain racing single-weight oils have ZDDP in it, but
it will NOT be the proper dosage for your turbo engine.
We have included special ordering information in this
Inner Circle mailing. We are only taking orders by email
on this product to the email address listed below. Orders
will ship the week of August 27th. However, we will not
charge your credit until we process your order.
Richard has gone to great lengths to make this project happen.
It is a well-known fact among engine rebuilders and
mechanics, older engines (especially pre-1988)
that have flat tappet setups require a well-known
oil additive called "ZDDP." The additive ZDDP is made
up of Phosphorus, Sulfur, and Zinc. By using the
proper amount of these three chemicals, it makes ZDDP.
This additive has been the most effective extreme
pressure additive found in quality motor oil for
nearly 70 years. However, in recent years, this additive
has slowly been removed from the various motor oils you
can buy at the local parts store for your Turbo Regal.
For that matter, this additive is needed by not just
the Turbo Regals but all of the older performance cars.
ZDDP is a surface modifier. It modifies bearing and
journal surface characteristics to prevent metal-to-metal
contact. Under the right conditions of heat and pressure,
the zinc in the ZDDP actually plates over the contact
surface and provides a sacrificial coating. As it breaks
down, it dissipates back into the oil solution and remains in
suspension until the right conditions arise and the
process starts over again. This reduces the tendency
of parts to scuff and gall under heavy-loaded
boundary lubrication situations.
Camshafts and lifters found in high-performance
engines definitely fit this category due to high
velocities and accelerations required to open and
close valves many times per second.
This condition is also found in the piston wrist
pins. In other words, this description clearly fits
the characteristics of our Turbo Regals engines.
Normal amounts of this additive of ZDDP in 1988
API grade SG oils was in excess of 0.12%.
The API grade of oil specified for our Turbo Regal's
in 1987 was SF. SF oil had ZDDP concentrations in
excess of 0.15%.
Until recently it was considered normal to add a
bottle of GM EOS to these types of oil for engine
break-in. However, recently GM has discontinued EOS
from their product line, making it a moot point.
Upon recent testing of a sample of EOS, we found the
concentration was 0.71% by weight. Since EOS came in a
16-ounce bottle, this means to boost a modern day oil
to protect pre-1988 engines intended for normal
driving, it would require two bottles of the 16-ounce EOS.
This is a costly investment each time you do an oil change!
Now that the EPA requires new car manufacturers to
guarantee catalytic converters for over 100,000 miles,
the use of such a product would most likely void new
car warranties. Newer cars with roller rocker assemblies
do not need ZDDP.
A product such as this would probably have to carry a
warning on the label stating *OFF ROAD USE ONLY*. With
the new EPA guidelines for oil manufacturing and
grading, it is clear that without using exotic
aftermarket oils or diesel oils, currently there really
is no good choice of what to use in older cars
that require ZDDP to protect the engine internals.
There are still some single-weight oils that contain
various amounts of ZDDP for Turbo Regal engines, but
being a single-weight oil is not what is required in most
performance engines pre-1988.
Richard Clark has packaged the proper concentration
of the ZDDP formula for a typical pre-1988 engine,
put in a ready-to-use two-ounce bottle. The proper amount
specifically for a five-quart engine.
Richard expects to have the legal issues resolved and
exact correct wording on the bottles by early fall.
In the meantime, we are able to offer introductory
sample-style bottles in various packaged amounts to
accommodate your needs.
Because of our close association with Richard Clark
and his various companies, we are the main supplier
of this highly sought-after product.
Richard has been working on this project for most of
this current year. He has a number of the various
other marketed additives analyzed and determined NONE
have the proper amount of ZDDP in it for a normal
five-quart engine requiring API SF spec oil.
At our upcoming Reunion event, Richard will be giving a
presentation on this important subject and will be
presenting test results from a major independent
petroleum testing lab on oil and oil additives that
are commonly available.
Remember, one single two-ounce bottle will treat a
regular five-quart engine, such as the Turbo Regal.
You have to ask yourself... how important is the
internals of your Turbo Regal engine?
Some of you probably own other pre-1988 performance cars.
This product will work on ALL GM-Ford-Chrysler performance
engines. The list of potential buyers is endless.
This additive is virtually impossible to find in its
pure form. In very limited amounts, it can be found in
some oils and additives but this gives you the choice of
using any premium oil (this includes any synthetic and
viscosity) that you may choose.
My area dealers say "it is discontinued..." :frown:
Isn't BG MOA just as good???
The latest oil analysis shows the zinc has been reduced significantly to about 500ppm....
