Rislone Engine Oil Supplement with Zinc Treatment is a petroleum oil performance supplement “booster” containing high levels of ZDDP (zinc dialkyldithiophosphate) Zinc and Phosphorus additives to help better protect internal engine components including pistons, flat tappet camshafts, lifters and the valvetrain. This is especially important at engine start up, when most wear is done. That is why they say one of the worst things you can do is start your engine.
ZDDP, also called ZDP, is short for zinc dialkyldithiophosphate, is basically a combination of zinc and phosphorus. When put under pressure, like between a flat tappet camshaft and a lifter, it attaches to the metal surface and becomes a sacrificial wear material. Beyond being an anti-wear additive, it also is a corrosion inhibitor.
Over the years motor oils have been updated to meet the needs of changing engine designs. In the past the oil companies were able to do this and keep the engine oil backward compatible, meaning this engine oil worked on new and old engines. However, now with the reduction of Zinc in the oil, these oils sold today do not offer the protection needed for older engines.
The common element between all of the engine components is the oil. Oil is the life-blood of the engine and is pumped under pressure to the internal parts. Engine oils are generally used to reduce friction between moving parts. In addition to lubricating, motor oil must cool, provide corrosion protection and a method of removing contaminants. The main parts needing oil for lubrication is the valvetrain including the camshaft & lifters, bearings and pistons. When installed, Rislone Engine Oil Supplement with Zinc Treatment cools and lubricates these moving parts better then oil alone. The clinging properties hold the oil to metal parts preventing wear and dry starts. Special additives also prevent oil thinning at high temperatures where normal oil fails. The ZDDP creates the sacrificial (disposable) layer on any component where metal to metal contact happens preventing the metal itself from being worn away.
Some additives are designed for break-in use only. Other additives make wild claims about coating the inside of the engine with Teflon type additives, but no real proof has been established to back up these claims. Rislone Engine Oil Supplement with Zinc Treatment uses proven ZDDP technology along with our 90 plus years of oil additive knowledge to protect the moving parts of your engine to be used after break-in.
No, you should not use Engine Oil Supplement with Zinc Treatment in 2005 and newer gasoline and 2007 and later diesel engines. Current oils have enough Zinc to protect moving parts inside newer engines. However, to help prevent sludge and keep that engine clean, it is recommended to use Rislone Engine Treatment p/n 100QR or 4102 on all newer engines.
Break in additives contain extremely high concentrations of ZDDP and are only designed to be left in the engine for a short period of time. Many of these additives don’t contain detergents or other lubricity additives important to keeping your engine clean and lubricated for thousands of miles. Rislone Engine Oil Supplement with Zinc Treatment not only contains the correct amount of ZDDP, but also the other additives important to protecting your engine. Do not use as a break in additive.
Rislone Engine Oil Supplement with Zinc Treatment contains copolymer esters (Tackifier) that have an affinity (attraction) for metal surfaces. This allows the oil to hold onto the metal surface instead of just running off like normal motor oil does over time. This along with the ZDDP creates a double layer of protection.
Yes, Rislone works with all petroleum-based motor oils including conventional, high mileage and synthetic formulas.
(Do not overfill)
GASOLINE ENGINES (Cars & Light Trucks)
1996 and older – Add one bottle to engine crankcase.
1997 to 2004 – Add approximately 1⁄2 bottle (5.5 ounces) to engine.
DIESEL ENGINES (Light, Medium & Heavy-Duty)
2006 and older – Add one bottle to engine crankcase for every 5 quarts of oil capacity.
For 4-stroke marine & motorcycles (dry clutch only), agricultural, industrial and racing applications use 2 ounces for every quart of capacity.
For best protection, use Rislone Engine Oil Supplement with Zinc Treatment with every oil change. Also can be used to top off oil as needed to improve engine protection between oil changes.
When used in combination with a good quality motor oil, Rislone Engine Oil Supplement with Zinc Treatment will last until your next oil change. Follow the manufacturers recommended oil change intervals for your particular vehicle and make sure to add with each oil change.
Yes, it is recommended to use at a 7% ratio for all 2006 and older diesel engines.
As we get older, our bodies need extra vitamins and supplements to keep them running like they used to. Car engines aren’t much different – they still fall victim to wear and age. Modern conventional motor oils lack the metal protection older or high-performance engines require. That’s why we created the Rislone 3X Concentrated Engine Oil Supplement with Zinc Treatment. This product is a great performance booster that helps protect older internal engine components. Kind of like a multivitamin, right? Only this one has ZDDP, the best form of zinc and phosphorus protection available anywhere in the automotive world.
This high performance formula stabilizes the motor oil to insure against viscosity and thermal breakdown. It also reduces friction and wear, especially at start-up, helping to eliminate dry starts. Less friction means less wear and a cooler-running, longer lasting engine.
Most drivers know that having adequate engine oil is important to the longevity and performance of your vehicle. But do you know what ZDDP is all about?
Many products claim to protect your engine, but at Rislone we’ve spent nearly a century proving it – on the highway and on the racetrack. We have taken the time to study, formulate and test our formulations in the lab and in the real world. We take customer feedback and usage data to improve our products. Today, we have some of the highest-performance engine oil treatments on the market.

“Love this stuff... Been using it since I noticed what looked like scratches on my cam lobes. Ever since I started using it my lifters are way quieter and the wear on my cam loves seems to have stayed at the same level since I began adding this to my oil. Highly recommend it!”
“I add half a bottle at each oil change, and I love it. I've used this for the last 10 years in my 2004 Jeep Grand Cherokee with the 4.0 inline 6. Always use the cheapest 10w-30 oil I can find and a better filter.”
“I used two bottles during my hydraulic flat lifter cam break-in with no problems. After the break-in, I again intrusted this product to protect my new engine. It has performed as advertised!”
“We have a S-10 drag truck with a 408 big block Chevy engine. We run a solid flat tappet cam. I use this as a zinc supplement on each oil change and haven't had any valve train problems at all.”
