ENGINE OIL SUPPLEMENT
with ZINC TREATMENT 3X CONCENTRATED ZDDP
P/N 4405
What is Rislone Engine Oil Supplement with Zinc Treatment?
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.
What is ZDDP?
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.
Why do I need ZDDP?
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.
How does Rislone Engine Oil Supplement with Zinc (ZDDP) Treatment work?
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.
What are the benefits of Rislone Engine Oil Supplement with Zinc Treatment over
other engine additives?
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.
