Hi, I'm Lake Speed Junior from Driven Racing
Oil, and today I'm here to talk to you about
zinc and your cat.
Not that kind of cat.
I'm talking about your catalytic converter.
A frequently asked question we get all the
time is, "If I run a high zinc oil, is it
going to damage my cat?"
Well, rest assured your cat is not going to
explode because of using a high zinc oil.
Just forget about that.
It's not a concern.
Go back to the ogity two days, in the very
beginning, when they started reducing the
levels of ZDP in the oil.
We still had 1,000 to 1,200 parts per million
of ZDP in the oil, and the catalytic converters
were not exploding.
They weren't dying.
It's not even the thing to be concerned about.
In fact, most European spec oils already have
a higher level of ZDP.
It's more urban myth than it is anything else
that a high level of ZDP is gonna kill your
cat.
Now you're probably saying, "Well, hang on.
Well, then why in the world did they reduce
the level of ZDP and blame it on the cats?"
Well, as with most things, there's an issue
when it comes to quality.
You have to remember that the API performance
specifications are actually a minimum level
of performance.
Kind of like the C students in medical students,
right?
You're still doctors, but they're not the
one you want having doing brain surgery on
you.
So with this being said, when you have a low
quality oil that was a high level of ZDP,
you tended to have more evaporation of the
oil.
Basically high oil consumption is what caused
the zinc that's inside your engine to get
to the catalytic converter.
If you think about that, if you never allow
the zinc to get out of the engine, how does
the cat know there's any zinc in the oil?
It doesn't.
Using a high quality oil, like the Driven
Racing Oils, limits the amount of evaporation,
the amount of oil consumption, and when you
limit consumption you protect the cat.
So it is possible to have a high level of
protection for both your engine and your catalytic
converter even by having a high zinc oil,
because a high zinc oil that's high quality
limits oil consumption, and I'm living proof
of this.
My own personal vehicle is a 2005 Chevy Silverado
that has over 200,000 miles on that engine
and catalytic converter, all running high
zinc, high-quality Driven Racing Oil.
So don't worry about your cat and the zinc,
it's just fine.
