Most lubricant manufacturers make a small number of automotive
products, maybe three motor oils, two gear oils, a grease, and an ATF.
All applications have to fit one of these universal products.
Unfortunately, the automotive world is not quite so simple. And even if
one of these compromise products works, perhaps a product formulated
with the intended application in mind might provide a few percent
better power, efficiency, or lap times.
Red Line Synthetic Oil Corporation has the most complete line of
automotive lubricants available. Red Line realizes that reducing
friction is necessary in a rear differential, but that friction is
actually necessary in a transmission so that synchronization may occur.
No lubricant can do a perfect job for both. The same is true for
engines. Reducing friction is a goal of engine lubricants, but the
detergents used in most motor oils compete with the friction reducers
for the metal surface. So if you want the lowest friction, use an oil
formulated for the lowest friction. Red Line manufactures Racing Oils
which contain few detergents, so no compromise has to be made.
First we will discuss motor oils. Most motor oils are designed to
lubricate three test engines - a Ford 4-cylinder, an Oldsmobile V-6,
and single cylinder Caterpillar diesel. Oil formulations are optimized
to adequately lubricate these engines, but not so well that a lot of
money is left on the table - the motor oil shelves are very cost
competitive. These oils will adequately lubricate most automotive
engines, even many high-performance engines, because the manufacturers
know that the highway patrol will catch you before high-speed operation
can cause significant damage.
Now take these products to the track and all bets are off! Try an
endurance race with the 5W30 oil that the manufacturer recommends.
Well, maybe before you try it you ought to take a survey of engineers
who work for the auto manufacturers to find out if any of them would
even use these "Fuel Economy" oils for their own passenger car during
the summer.
Red Line lubricants work under the demanding conditions of
high-performance driving. Red Line has been manufacturing
high-performance synthetic lubricants for over twenty one years. During
the earlier years many would say, "Well, if synthetics are so good, why
doesn't the Brand X Oil car use one. Well, now we find that the Brand X
team was using synthetics for years (maybe even Red Line) and that many
of the major oil marketers now sell synthetic lubricants in an attempt
to keep up with technology. Synthetics as a class of lubricants have
some significant advantages over even the best petroleum lubricants.
The first advantage is being able to manufacture multigrades that will provide excellent high-temperature and high-speed
performance. In order to manufacture a multigrade petroleum, say a
10W30, a 10W oil is thickened with a polymeric plastic substance much
like STP. This enables the oil to flow like a 10W oil when cold, but
appear to be an SAE 30 when measured at the high temperature (100
degrees C). The problem is that the high temperature testing is done in
a tube at the equivalent shear of a very low RPM. At high RPMs a 10W30
multigrade petroleum will appear to have a viscosity between a 10 and a
30 and at very high RPMs the viscosity will be a 10. A synthetic
generally does not thicken as much at cold temperatures or thin as much
at high temperatures as a petroleum oil, so large quantities of
unstable thickeners are not required. The advantage is that at high
RPMs and high temperatures a synthetic 10W30 can actually provide
thicker oil films than a straight SAE 30. However caution must be
advised when thinking about synthetic 5W40 and 5W50s. Here significant
amounts of the thickeners used to make petroleum multigrades must be
used so that the high-shear viscosity will provide the equivalent to a
petroleum SAE 40. This chart shows how the viscosity of a lubricant
varies in the different shear zones of an engine.
The superiority of synthetics lies in the fact that a 10W40
synthetic can provide the high-shear protection superior to a petroleum
20W50 in the bearings and cams, while providing a much lower viscosity
on the cylinder walls and in the ring pack. This lower viscosity
produces more power and also better efficiency and fuel economy.
However, wide range synthetics such as 5W50s use the same thickener
systems as petroleum 20W50s and suffer from the same viscosity losses
in the bearings and cams.
Red Line considers that in most cases an engine should not require
the viscosity of a 20W50 and would be simply sacrificing power for
doubtful advantage, but the 40Wt Race Oil (15W40) or 10W40 Motor Oil
provides significantly improved film thicknesses compared to a 20W50,
while providing the advantage of 1-3%
more power.
The viscosity characteristics is where the similarities of synthetics
end. Not all synthetics are created equal. If metal-to-metal contact
does occur, the amount of friction created can make a great difference
whether the bearing will spin or the cam and follower will create
tremendous heat and wear. This chart indicates that Red Line lubricants
provide significantly lower friction. Compared is Red Line with several
"high-performance" synthetic and petroleum lubricants. This reduced
friction means less heat is generated, so temperatures are reduced,
wear is reduced, and more power is transferred to the wheels. Another
significant property of Red Line is the stability of the oil with use.
Note that after 15,000 miles Red Line produces less friction than the
other popular synthetics when new, and some formulations are very weak
in friction properties with use.
Red Line lubricants also excel in wear protection. Red Line
provides several different antiwear additives in each lubricant to
provide wear protection over a very wide range of conditions. The data
from two ASTM wear tests below indicate that Red Line has a distinct
ability to carry a greater load (film-strength), and that less wear is
produced per unit of load. Across the range of loads which your
automotive equipment can encounter, Red Line can provide less wear and
a much lower chance of catastrophic failure than other petroleums and
synthetics. This can make the difference between an engine saved and
one which is destroyed when a mechanical component such as a connecting
rod bolt breaks.
Red Line also will reduce lubricant temperatures significantly.
Track testing done by the Delco Chassis Division of General Motors
showed a reduction in both engine and transaxle temperatures of at
least 30 degrees F when comparing Red Linemotor oil and to a major
synthetic brand. These tests were performed in a Oldsmobile Calais and
a Chevrolet Berreta GTZ equipped with the High-Output QUAD 4.
Another significant difference between Red Line and other synthetics and petroleums is the ability
to withstand high temperatures without decomposition. The polyo lesters
used by Red Line have a significantly greater degree of thermal
stability compared to the synthetic hydrocarbons and petroleum
lubricants. In fact, the polyol esters are the only lubricants capable
of properly lubricating a modern jet turbine engine. This enhanced
thermal stability can provide improved lubrication in the extreme
temperature regions such as turbocharger bearings and upper ring area,
provide improved cleanliness, and allow extended high-temperature
operation. The chart above compares the ability of several synthetic
and petroleum lubricants to withstand decomposition at a temperature of
500 degrees F for three hours.
The reduced friction, lower wear, and increased thermal stability
all indicate a product which is superior to other commercially
available petroleum and synthetic lubricants. This translate into
improved protection and more power to the wheels. For example, Boris
Said has won the SCCA SSGT class for three years straight using Red
Line lubricants in his Camaro with a 305 Chevy V-8. This car has over
7,000 mile of sprint racing on it, all with the same drivetrain
components. The engine is taken apart every year, new bearings are
replaced simply as a precaution, not because they are damaged. The
original rings are still in the engine and there is no evidence of wear
on the rings or cylinder walls. This car has been incredibly low-cost
to maintain. Boris can without a doubt attribute his victory to Red
Line Oil. During the championship race his power steering hose broke on
the first lap, pumping all of the fluid out of the system. Pumps aren't
made to last 45 race miles without fluid. Pump seizure was a certainty
which would have put him out of the race. But the pump never seized
with the remnants of Red Line Power Steering Fluid in the system.
Another example is Wayne Torkelson, the owner and driver of the
first Ford doorslammer to ever reach 200 mph. Wayne competes in the
IHRA Pro Mod circuit with a blown alcohol '55 Thunderbird. As soon as
Wayne switched to Red Line Gear Oil he picked up 1.5 mph on the top
end. Previously he had been wearing out a ring and pinion every 20-25
passes. Since then he has yet to wear out a ring and pinion in four
years. Prior to switching to the motor oil, he would get 3-4 passes on
a set of oil rings. Now he gets 85 passes or more. In fact, if the
engines have no breakage problems, he can run a whole season on the
same rings and 40 passes on a set of bearings.
A National Record Holder in SS/DA, who races a '67 Corvette Coupe
with a 427/Powerglide combination, one day switched to Red Line 30WT
Race Oil and LightWeight Gear Oil and picked up seven hundredths. It
would cost thousands to pick up that much with engine work. After 50-60
passes the motors are disassembled and the internal components look
perfect - bearings, rings, cam, and cylinders. Jim Jones, the owner of
Traco Engineering, has built 350 V-8 motors for Corvette endurance
racing for years. His engines are run by different teams using
different oils, many of them other synthetics. He will get engines back
from the different teams after a 24-hour race. All engines ran at the
same track and have the same number of miles, but he can always tell
the Red Line engines from the others. The difference in wear is
incredible. The most noticeable difference is in the valve guides.
After 24-hours operation on other synthetics they are completely worn,
while with Red Line they are still in good condition.
Dyno tests have shown Red Line to provide between 1-3% improvement
in power. In a 460 big-block Chevy at 5500 rpm and 175 degree F oil
temperature, a petroleum SAE 30 race oil provided 526.8 hp while the
Red Line 30WT Race Oil provided 534.4 hp, and increase of approximately
1.5%. Greater differences are usually obtained if the temperatures are
higher because of the better viscosity at high temperatures.
Red Line manufactures a cooling system additive called WaterWetter
which is capable of reducing the coolant temperature of a
high-performance vehicle by 15-30 degrees F and can provide even
greater reduction in cylinder head temperature which means greater
volumetric efficiency and allows more spark advance. WaterWetter also
provides rust and corrosion protection in plain water which can provide
additional cooling efficiency compared to antifreeze.
