Why
should I use Royal Purple?
There
are a variety of reasons to use Royal Purple including
increased horsepower, improved fuel economy, a cleaner
engine with fewer emissions, reduced wear, reduced oil
consumption, improved corrosion protection, and ultimately
a longer lasting, smoother and cooler running engine.
Why is Royal Purple better than other oils?
The
superior film strength, created by our proprietary Synerlec ä
technology, offers 4 to 5 times better metal to metal
protection than
other oils, petroleum or synthetic.
Are
your products compatible with other petroleum or
synthetic
based oils?
Yes.
Royal Purple lubricants are fully compatible with all
currently available petroleum/synthetic blends, or full
synthetic based oils.
How
often should I change Royal Purple in my passenger car?
If
your vehicle is under manufacturer warranty, we recommend
following your manufacturers recommended oil change interval.
If your vehicle is not under warranty, we recommend changing
Royal Purple approximately every 10,000 – 12,000
miles. However, we recommend to continue changing the
filter every 3000 – 5000 miles to minimize the accumulation
of dirt, fuel and water.
Can
I put Royal Purple into my brand new car?
We
recommend switching to Royal Purple after the manufacturer’s
first scheduled oil change. This allows the engine time
to break-in (seat the piston ring to the cylinder wall).
The exception to this is the diesel pickup (Ford, Dodge,
Chevy, GMC). These use a very hard piston ring under high
compression and it takes longer for the rings to seat.
In these applications we recommend switching to Royal
Purple after 5000-10,000 miles (depending on engine loading).
Does
Royal Purple meet the manufacturer’s requirements?
Yes.
Royal Purple is “API Warranty Approved”, so
it meets or exceeds the requirements of manufacturer’s
new car warranties.
Does
Royal purple have oils for use in diesel applications?
Most
manufacturers recommend using 15W40 oil in their diesel
engines. Royal Purple’s 15W40 has additives specifically
designed for use in diesel applications and exceeds API
certification requirements for diesel engines.
I live in cold weather what is the pour point of your oils?
The
pour point of all of our SAE grade oils is less than –30
F and varies from oil to oil. This should be more than
adequate as ambient temperature typically does not get
that cold.
What
type of oil should I use for my turbo-charged engine?
For
street driven vehicles, it is best to run the manufacturers
recommended viscosity. For competition use we recommend
our Racing 41 or Racing 51.
Is Royal Purple OK for use on a motorcycle with a wet clutch?
Yes,
Royal Purple has been found to work very well in these
applications.
Can I use Royal Purple in my Harley?
Yes.
Royal Purple has had great success in the Harley market.
For pre-Evolution motors, our SAE 50 is recommended. For
Evolution motors, we recommend Royal Purple 20W50. For
Sportsters, Royal Purple 15W40 can also be used.
My
Harley has a primary oil tank. Can I use Royal Purple?
Yes.
Royal Purple will work in the primary oil tank. We recommend
using the 5W30, Racing 21 or Racing 41.
Will Royal Purple cause my engine to leak?
Royal
Purple will not cause an oil leak. In some instances,
usually in older engines, there may be a bad seal or cracked
gasket that is not leaking because it is filled with oil
sludge, lacquer, and varnish deposits. Synthetic oils
are designed to carry away deposits, there have been cases
where oil has leaked after those deposits are removed.
If an engine leaks after putting Royal Purple or any synthetic
in, the oil is not causing the leak, it is exposing an
existing leak. In these cases or in older cars where this
might be a concern, it may be best not to recommend a
very lightweight oil. In the long run, it is better to
replace a faulty gasket than to leave those deposits in
the engine.
What
will putting Royal Purple into my older car do for me?
Royal
Purple will breathe new life into older engines. The polishing
characteristics of the oil will help smooth out the cylinder
walls and bearing surfaces. The film strength of the oil
will help increase fuel mileage and keep the engine cleaner
resulting in reduced emissions, a big benefit to older
cars.
Should I use an oil additive with Royal Purple?
No.
With the addition of an additive you would be creating
an untested and unproven compound. We are constantly testing
and have yet to find an additive that enhances the performance
characteristics of Royal Purple. In fact, several of the
additives when added to our products can result in decreased
performance rather than performance gains as claimed.
Does
Royal Purple Gear Oil meet the newer GL-5 for Transmission
or Differential use?
Yes,
all of our Max Gear gear oils exceed API,s stringent GL-5
specifications, as well as contain a friction-modifying
additive for limited slip differentials. Viscosity should
follow manufacturer’s recommendations.
Will
Royal Purple Gear Oil also meet GL-4 requirements?
Yes,
GL-4 requirements call for a non-corrosive fluid for softer
yellow metals that are in these systems. Royal Purple
Gear Oils are non-corrosive, yet yield exceptional film
strength through the use of Synerlec.
What
should I use for a Manual Transmission Fluid (MTF)?
As
always, if your car is under warranty, we suggest following
your manufacturer’s recommendations. In most passenger
cars we recommend using Royal Purple Max Gear 75W90. Some
people may want to use something lighter, in which case,
our ATF or Racing 41 would be good suggestions. Racers
may even want to run the Racing 21, which is fine. Many
new cars use an ATF or engine oil.
Will
Royal Purple help shifting in my automatic transmission?
Yes.
Royal Purple Max ATF has shown time and time again to
help automatic transmissions shift smoother and run cooler.
Is
it approved?
Yes.
Royal Purple Max ATF meets both Dextron Type III and Mercon
III specifications.
Will
Royal Purple Max ATF work in older transmissions?
Yes,
Royal Purple Max ATF is backward compatible with most
automatic transmission fluids. One exception is the Type
F fluid used in older Ford / Lincoln / Mercury vehicles.
The seals used in these older vehicles may not be compatible
with newer fluids, however, if the transmis- sion has
been rebuilt within the past ten years or so, it probably
has seals that are compatible for use with newer fluids.
In any application calling for newer Mercon or Dexron-III
fluids, Royal Purple is an excellent choice.
Is
it necessary to drain the torque converter when changing
to
Royal Purple Max ATF?
Royal
Purple Max ATF is fully compatible with other automatic
transmission fluids. The mixed fluids will not have the
maximum protection from thermal breakdown. To get the
full benefits of the Max ATF, it is advisable to drain
the converter or have the transmission flushed. If this
is not possible, we recommend changing the fluid again
after approximately 10,000 miles. After that, it would
be fine to change the fluid at the manufacturer’s
recommended interval Racing
Applications
What
product should I use in my race car?
Royal
Purple has several options for racers. Our “street
oils” are formulated to outperform any of the other
“racing” oils on the market. In addition,
our racing oils will offer even more protection than the
street oils. The following are some guidelines that may
be helpful in product use determination:
As
a starting point, we recommend the Royal Purple Racing
oil that is closest in viscosity to theoil
the racer is currently using. Eg. Racer using Kendall
20W50 Racing currently would be safeusing
Royal Purple 20W50 or can upgrade to our Racing 51. The
tolerances to which the motor was built can play a role
in an oil recommendation. Loosespecs
(e.g. greater that 3 thousandths) might require a slightly
heavier oil that a motor built to tighter
specs (e.g. 2 thousandths) to maintain idle oil pressure. As
there is an inherent tradeoff between protection and performance,
the following may help.Keep
in mind that it is much easier to be conservative with
a heavier oil and then go lighter whencomfortable.
Can
I run your oils with exotic fuels (alcohol, methanol, nitro,
etc.)?
Yes.
As illustrated above, Royal Purple lubricants can be used
with exotic fuels. For the best protection, we have formulated
our 11 and 41 racing oils specifically with this in mind.
These two oils are made to hold up even better than our
other racing oils in alcohol and methanol applications.
Does
this mean that I should not run your other oils with these
fuels?
Not
necessarily, our other oils will still perform better
than conventional racing oils. The 11 and
41 have specifically taken these uses into account.
Can
I break in my racing motor with your oil?
It
is not recommended to break-in an engine using Royal Purple,
as the film strength of the oil may not allow proper seating
of the rings. We recommend using a quality petroleum based
oil for break-in purposes. Follow your engine builder’s
guidelines for break in procedure. Typically
the rings should seat within the first 5 to 7 times that
the engine is brought to temperature.
How
will running your product effect my oil temperature?
In
most instances, we have found that running our products
results in lowering oil temperatures by 5-20 degrees F.
Might
my oil temperature increase with your product?
There
have been isolated instances where we have received reports
of temperatures increasing. Due to the heat carrying capabilities
of the oil, the oil is absorbing more of the heat from
theengine,
and the oil is not being cooled efficiently. The solution
would be a more effective oil cooling system.
How
will running your product effect my oil pressure?
When
switching to Royal Purple it is not uncommon to see an
oil pressure decrease of anywhere 5-15 lbs. This is to
be expected and should not cause any alarm.
How
often should I change the oil in my race car?
This
depends entirely on the application. A good rule of thumb
is to find out the racer’s current type of oil and
oil change interval, if he/she is racing a petroleum oil,
they should feel comfortable doubling or tripling their
change interval. If he/she is running another synthetic,
they can still feel comfortable doubling their change
interval.
What about running nitro-methane?
Our
full line of “Nitro” oils have been specially
formulated for use in high power nitro-methane and alcohol
applications. These oils are the same ones used by Top
Fuel teams and some of the top Blown Alcohol teams in
the country.
Purple
Ice
Can
I run Purple Ice instead of coolant/antifreeze?
No.
Purple Ice is not intended to replace coolant/antifreeze
in street applications. Antifreeze is still needed to
decrease the freezing point of the mixture. Even in warm
climates, we recommend running at least a 15% antifreeze
mixture.
Why
is Purple Ice better than existing radiator additives?
Like
the existing radiator additives, Purple Ice provides both
additional cooling to the vehicles system by reducing
the surface tension of the mixture. Additionally, Purple
Ice provides protection to the fragile metals from corrosion,
erosion, and electrolytic damage. This benefit is not
offered from other products.
Will
increasing the Purple Ice ratio improve the performance
characteristics?
No.
Purple Ice is intended to run at approximately 1oz. of
additive per quart of water/antifreeze mix. Increasing
this ratio will not result in additional heat transfer.
Is
Purple Ice suitable for use in diesel applications?
Yes.
Purple Ice excels in both gasoline and diesel environments.
Will
Purple Ice provide protection from cavitation corrosion?
Yes.
The level of nitrite contained in Purple Ice is sufficient
to provide protection from cavitation corrosion. Where
nitrite levels are critical, the ratio of Purple Ice can
be increased from 1oz. per quart to 1 ½ oz. per
quart.
Is
Purple Ice compatible with the newer generation of factory
coolant/antifreezes?
Yes.
Purple Ice is fully compatible with the newer fluids used
in some late model vehicles.
