Shop ZDDPlus ZINC ADDITIVE

ZDDPlus ANTI-FRICTION OIL ADDITIVE



ZDDPlus® contains the exact concentration (approximately 0.15%) of ZDDP (Zinc DialkylDithioPhosphate) that was available in motor oils under the "SF" category.

The motor oils today carry the "SM" category designation.

Today car manufacturers must warranty their catalytic converters for 100,000 miles or more. In order to meet this requirement, oil companies have had to eliminate the ZDDP older muscle cars need to protect their flat-tappet cams.

ZDDP is not an issue of concern for modern vehicles with roller rockers. The issue arises with older performance cars with flat-tappet camshafts.

ZDDP has been an important additive in engine oils for over 70 years and has had an excellent track record at protecting the sliding metal-to-metal cam lifter interface. ZPPD protects by creating a film on the cams and flat lifter contact points in response to the extreme pressure and heat at the contact point.

The company behind this project has a huge car collection centered around 1986-1987 Buick Turbo Regal (Grand Nationals). It was developed to protect these car engines and other classic and performance engines (cars, trucks, tractors, motorcycles, boats, etc.)

ZDDPlus® has been tested and compared to many of the other available additives on the market today by labs specializing in oil testing. If any of the other products contains the proper 0.15%, it would clearly have to indicate on the bottle that it is NOT meant for OBD II cars. Adding the proper amount of ZDDPlus® to your regular oil or synthetic oil provides you with peace of mind.

While it's true oil has vastly improved over the years, the amounts of ZDDP required for the older muscle cars has greatly diminished. This concentrate will mix with any oil you are currently using; synthetic or regular. It has a long shelf life, as long as it is stored in its sealed container and temperatures stay under 120 degrees.

Did you know modern oil has changed?


After 70+ years of trouble-free, metal-to-metal engine protection, the E.P.A. and car manufacturers are forcing ZDDP (Zinc DialkylDithioPhosphate = zinc and phosphorus) from domestic motor oil because of the warranties on catalytic converters.<

If your engine was designed prior to the 1990s, the non-roller lifters (flat-tappet cams) require ZDDP in the motor oil to avoid premature deterioration. Don't let the lifters run metal-to-metal. Keep ZDDP, via ZDDPlus®, in your car's motor oil. Add a 4 oz bottle of ZDDPlus® to every 4- to 5-quart oil change. Just one bottle of ZDDPlus® bring the current available "SM" oil (synthetic or conventional) back to the "SF" specifications.

One bottle of ZDDPlus® contains more ZDDP than two bottles of GM's EOS.<

Safe, proven ZDDP EP agent takes the worry out of using new oil formulas in classic engines.

Restores ZDDP to the optimum level which existed when your classic car or muscle car was new.<

Turns modern SM quality oil into the ideal oil for older cars, trucks, tractors, motorcycles, boats, etc.

Compatible with ALL high-quality oils, standard or synthetic. You choose your own type of oil.

Reduces cam and lifter wear in high-performance flat-tappet engines compared to a SM rated oil.

One 4 oz. bottle of ZDDPlus® per oil change with SM oil is more economical than 5 quarts of exotic oil.

ZDDPlus® eliminates using:


  • Diesel oil with incorrect viscosity or detergent.
  • Racing oils formulated with little or no detergent.
  • Break-in oil supplements for daily driving.

There is nothing in ZDDPlus® that was not originally in motor oil back in 1988 and prior.

CAUTION - ONLY USE IN CARS PRIOR TO OBD II CARS

ZDDPlus™ QUESTIONS & ANSWERS

What is ZDDPlus™?

ZDDPlus™ is an oil supplement that contains very high concentrations of the well-known additive ZDDP (Zinc Dialkyl-Dithio-Phosphate), which has been the primary EP (Extreme Pressure) ingredient in all quality motor oils for over 70 years.

Why do I need ZDDP?

The EPA has put stricter emission requirements on new cars, which have influenced manufacturers to remove ZDDP from motor oils. If you have an older car that was specified to use SF or earlier motor oil, its design requires ZDDP. Your car could be damaged with the use of modern SM oils.

What do the oil grades such as "S" indicate?

In the API (American Petroleum Institute) Classification System, "S" and "C" are the two basic application categories of oil. "S" is intended for gasoline use and "C" is intended for diesel use. "A" was the first grade in each category and resulted in "SA" and "CA" grade oils. Each progressed farther up the alphabet as new grades of oil were introduced. The newest grades are “SM” and “CJ” respectively.

Aren't the newer oils better than the older oils?

Historically, every new grade of oil introduced since the 1930s was better than the previous grade and could be considered &:improved"; with one exception. The original SA grade was straight mineral oil (non-detergent and without additives) and SB contained additives, which could not be used in the earliest cars specified for SA. While it is true that SM oils are better for newer cars, they are not better for older cars. Simply put, the newer and/or better oils are not backward compatible for older cars, primarily due to the gradual reduction of ZDDP starting with SG grade in 1988.

How much ZDDPlus™ should I add to my oil?

One bottle of ZDDPlus™ will raise the ZDDP level of SL or SM spec oil to the standards that were in place when SF (or earlier) oil was specified.

What if my oil already contains some ZDDP?

ZDDP is most effective if the concentration is between 0.18 % and 0.2 % by weight. Tests have shown that concentrations above this amount, up to as much as several percent have no effect except to prolong additive life.

Can I use ZDDPlus™ with regular and synthetic oils?

ZDDPlus™ should be compatible with all conventional and synthetic oils intended for automotive use. Virtually all of these oils have contained higher amounts of ZDDP for years and only recently have the levels been decreased.

What is the shelf life of ZDDPlus™?

The shelf life of ZDDPlus™ is essentially the same as regular motor oil (many years) as long as a few conditions are met. The temperature should be kept below 120 degrees F and above 0 degrees. Until it is mixed with motor oil, ZDDPlus™ has a tendency to absorb moisture, not unlike brake fluid. Absorption of water will degrade its performance; however, the ZDDP can be restored by slowly heating to a temperature slightly above 100C.

When should ZDDPlus™ be added?

ZDDPlus™ can be added anytime, but the best time is whenever the oil is changed. A single 4 oz bottle ZDDPlus™ provides the proper concentration for a 4- to 5-quart oil change.

How long does ZDDPlus™ last?

Minute amounts of the ZDDP molecule in the ZDDPlus® form a necessary sacrificial additive which becomes depleted upon use. ZDDPlus™ is designed to last the life of a normal oil change for your vehicle; however, attention should be given to the categories of service known as “normal” and “severe.” The severe category includes stop-and-go driving and short trips, and results in shortened service life. Not only is the service life of ZDDPlus™ decreased, many other oil additives suffer as well.

Why should ZDDPlus™ not be used on OBD cars?

The key ingredient of ZDDPlus™ is ZDDP, which has been known to shorten catalytic converter life. Manufacturers have been redesigning engines for the last decade to minimize the need for ZDDP in order to lower emission levels.

Why not just use diesel rated oils since they contain higher levels of ZDDP?

Diesel engine requirements are much different than those of gasoline engines. The higher speeds and lower bearing surface-to-power ratios of gasoline engines require oil with higher shear ratings than most diesel oils. Diesels also have higher bearing clearances, which call for higher viscosity oils. The additional detergents required for soot control actually reduce the effectiveness of added levels of ZDDP found in diesel oils.

How does ZDDPlus™ compare to EOS?

Historically, EOS was the most concentrated ZDDP supplement available. It was intended to boost ZDDP levels of oils that already contained EP additives. ZDDPlus™ is packaged in a 4 oz bottle and contains twice the amount of ZDDP than there is in a 16 oz bottle of EOS. Therefore, it takes two 16 oz bottles of EOS to equal the same concentration of ZDDP in one 4 oz bottle of ZDDPlus™. ZDDPlus™ is intended to be used with newer oils with little or no ZDDP. EOS was discontinued by General Motors in the second quarter of 2007.

What about the claims of the various additives?

We make virtually no claims for ZDDPlus™ except it restores the EP function of the oil to the level originally required for your older car. Other additives make claims so ludicrous; they cannot be accepted based on common sense alone. Consider, for example, fuel mileage. The only proven fuel mileage claim is that of the newer lower viscosity API rated energy conserving grades of oil which claim 1.5% for the Type 1 EC, and 2.7% for the Type II EC oils. Note - This claim is in percent, not mpg. If an additive was to actually boost fuel mileage 20% or more, then auto manufacturers would have found the very cheapest method possible to increase their CAFÉ fuel ratings! If there was any truth to these claims, virtually every car built would certainly leave the assembly line with those products installed!

Can an oil or additive have Zn and not P and still contain ZDDP?

It is important to note that the wear protection properties are due only to the characteristics of the ZDDP molecule and not to Zn or P in the oil in other forms or from other sources. This means that if a particular motor oil mentions the addition of Zn alone, or P alone, the ZDDP molecule is not present in that motor oil. The ratios of Zn and P can be manipulated by simply adding zinc salts or phosphates, but again, this does not produce ZDDP and has no anti-wearing action.



Lastly, depleted ZDDP releases Zn and P into the motor oil and testing for levels of either of these pure elements is not a gauge of the status of the ZDDP level. What does this mean? If you see an oil additive or motor oil specifying only a level of Zn without a level of P, then there is no ZDDP in that product.

INTERNATIONAL ORDERING



TO OUR INTERNATIONAL CUSTOMERS:


In the past, we have used a separate order form for placing International orders. We have quit using that process and are requiring all customer to use the shopping cart system built into the web site and it's check out process.

If you simply want a quotation and are not ready to place an order, then cut and paste the contents of your shopping basket, take a screen shot of the basket, or make a list of items and send us a email requesting a quotation with shipping.

If you need shipping prices before you make your final decision to purchase, then you should request that quotation by email and not use the shopping cart checkout process because you will be paying for the parts at that time.

Since our shopping cart and shipping estimator will "NOT" correctly calculate shipping charges on International Orders, we have it set-up to where the shipping will be Zero Dollars ($0.00) when checking out. When the shopping carts address process learns you are not in the United States by selecting your particular country, that's when it switches to equal Zero. That does NOT mean shipping is free.

Upon completion of the check out process, you will have paid for your parts but NOT the shipping on those parts.

Once we look over your parts ordered and calculate shipping weights and box sizes, we will send you an E-Mail with at least one shipping option and maybe several. We utilize UPS, DHL and the United States Postal Service (USPS) to deliver your parts.

Once you pick a shipping carrier and agree to the quotation by returning the E-Mail, we will be sending a PayPal money request for the amount of the shipping to be collected. If the parts are expected to be shipping out quickly, then you may receive that email quickly. If the parts are going to need to be built or something is on back order from the list of parts, we may hold off sending that E-Mail until we have the shipment ready to go. It can vary from order to order as to how we do that. If you think you should be hearing from us quickly, but you don't, feel free to contact us.

If you have special shipping needs or requirements, during the checkout you will see a SPECIAL ORDER INSTRUCTIONS window. Enter that special information there.
