All Red Line Two-Cycle lubricants are designed to provide the greatest
protection and the maximum power from a two-cycle engine. Red
Line has many different two-cycle lubricants which vary in lubricity,
thermal stability, and ash-containing or ashless detergent type. The
greatest degree of cleanliness and lubricity is provided by our Two-
Stroke Racing Oil. The Two-Stroke Racing Oil provides the cleanest
and best lubricity, which is far superior to castor bean oil, petroleums,
and other synthetics. This lubricant provides excellent lubricity and
perfect cleanliness even in race engines operating at 15,000 rpms.
But not every engine has such demanding requirements. That is why
we have many other two-cycle lubricants to lubricate factory stock or
slightly modified engines with a less costly product without making
any compromise in durability. The main difference in our two-cycle
lubricants is the temperature stability of the basestocks used. The
more thermally-stable the basestock, the higher the cost of the lubricant,
with the Two-Stroke Racing Oil product being the cleanest and
most thermally stable product on the market and the Smokeless
being the least thermally stable within our product line. However, all
of these synthetic lubricants provide better cleanliness, better protection,
and burn cleaner than any petroleum or other synthetic product
available. Many engines will not see the extreme temperatures
encountered in racing situations and can be perfectly lubricated with
the Two-Stroke AllSport™ Oil, Watercraft or Snowmobile lubricants -
leaving no piston deposits. The Two-Stroke Racing Oil will tolerate
temperatures approximately 100°F greater than the Smokeless Oil
and provides perfect cleanliness in even the most extreme applications.
The graph above demonstrates the cleanliness capability of
Red Line lubricants compared to a high-quality petroleum NMMA TCW3
lubricant and other synthetics. The chart above indicates the
evaporation rate of different lubricants at 475°F. The time indicated is
the time required for the lubricant to decompose to a sticky mass
capable of sticking a two-cycle piston ring.
The NMMA TC-W3 lubricant is a baseline with which to judge the Red
Line lubricants. All Red Line lubricants provide significantly better
stability than the petroleum reference. This indicates that Red Line
lubricants will withstand the higher temperatures found in racing twocycle
applications and will also leave more lubricant on the cylinder
walls to assist in the prevention of piston scuffing. A competitive
synthetic two-cycle (B) showed very little deposit formation upon
heating, but evaporated very quickly, with little lubricant remaining
at temperatures found in the ring area. Another did not evaporate
as quickly and would provide better scuff protection than petroleum,
but has relatively poor ability to prevent ring stick.
Red Line lubricants are extremely clean and data below demonstrates
that Red Line lubricants provide better scuff protection and
reduced bearing and ring wear. Red Line can provide both better
cleanliness and reduced wear.
Two-Stroke Racing Oil / Two-Cycle Kart Oil - provides excellent
cleanliness and lubricity to keep even the highest-revving engines
perfectly lubricated. Terry Ives Industries obtained perfect engine
condition in their 100cc Yamaha KT-100 school karts after 25 hours
of use. In this same type engine under 3 hours of competition at
20:1, the piston clearance increased only 0.00025 inch. Racing
castor would provide between 0.001-0.002 inch wear under the
same conditions. No ring, ring land, or cylinder wall wear was
apparent in this 3 hour engine and skirt scuffing was virtually eliminated.
In the Rotax 256 In-line Twin and the 125 Single the results
were equally impressive. No obvious wear could be seen and skirt
scuffing was virtually eliminated. No carbon deposits were formed
and all combustion residue was easily wiped clean. Plug life is
greatly extended. Emmick Enterprises obtained similar results in a
Yamaha KT-100 which operates in the 350°-420°F cylinder head
temperature range and up to 15,000 rpms. No scuffing and very
low wear were observed after 7 hours of competition. A measurement
of the lower-end bearing indicated that Two-Stroke Racing Oil
provided less wear after 7 hours than racing castor or other
synthetics after only 45 minutes. Many kart racers report that they
can operate their engines at temperatures of 25°F greater than
when using racing castor or other synthetics, without fear of piston
sticking, enabling a considerable increase in power to be obtained.
Two-Stroke Racing Oil is also exceptionally clean and this cleanliness
makes it an extremely popular lubricant for jet skis, where it
provides very crisp throttle response, up to 2-3% improvement in
power, and will not leave a sticky residue in expansion chambers,
waterboxes, or down the sides of the ski. We have several years
experience with this oil in V-6 outboard racing in Champ Boats and
Off-shore racing where it provides improved power, half the wear of
other high-quality oils, and perfect cleanliness in even endurance
racing. Dyno tests have shown 2-3% improvement in power, using
a fresh engine, but the actual improvement is considerably greater
compared to other lubricants. As the engine wears and develops
deposits which restrict ring mobility and increase backpressure in
the exhaust, the power output declines. But with Red Line Two-
Stroke Racing Oil the reduced wear keeps the engine fresh and the
complete absence of deposits keeps power output high. Two-
Stroke Racing Oil can be used as a premix or as an injection oil.
Watercraft Injection Oil - is a high-performance all-synthetic
formula which is designed to provide maximum power and the
greatest protection and cleanliness in watercooled two-cycle
engines which recommend an NMMA TC-W3 lubricant. The
synthetic ester basestocks are biodegradable as determined by
tests acceptable to European and American Environmental
Agencies, providing significantly less water pollution than petroleum
two-cycle lubricants. This lubricant also has excellent high
temperature stability - much more stable than petroleum TC-W3

oils or other types of synthetics - providing less smoke, cleaner
spark plugs, and cleaner pistons. These basestocks are combined
with ashless deposit control and anti-scuff additives to prevent ringsticking
and scuffing under extreme temperatures and keep the
piston and exhaust ports clean. The slipperiness of Red Line
Watercraft Injection Oil can produce up to 3% more power and can
provide significantly longer bearing life than when using NMMA TCW3
Oils or other synthetics, even in oxygenated reformulated
gasolines. Red Line can be used as an injection or premix oil and
will dissolve in gasoline and remain soluble indefinitely. The rust
protection of this product is far superior to BIA or NMMA lubricants
which makes it suitable for marine use. This can be used in any twocycle
outboard engine up to 10,000 rpms.
Two-Stroke AllSport™ - is a high-performance all-synthetic formula
which is designed to provide maximum power and the greatest
protection and cleanliness in watercooled and air-cooled two-cycle
engines. The properties are the same as with the Watercraft Oil
above, but uses a low-ash chemistry which provides better cleanliness
in higher temperature air-cooled engines, while the WaterCraft
Oil provides better cleanliness in lower-temperature water-cooled
engines. Recommended for high-performance stock or slightly
modified engines and where ISO GD, JASO FC, or API TC lubricants
are recommended, but is not designed for outboard use. Red
Line AllSport™ Oil may be run in ratios between 16:1 and 100:1,
depending on rpms and engine manufacturer requirements.
Two-Stroke Snowmobile - same properties as AllSport™ with
low-temperature capability below -40°F (-40°C).
Two-Stroke Smokeless - is a high-performance synthetic formula
which is designed to reduce exhaust smoke. All Red Line two-cycle
lubricants produce very low smoke, but with Smokeless it is virtually
non-existant. The synthetic basestocks completely thermally decompose
in the combustion process, helping to reduce petroleum pollution.
This lubricant also has excellent high temperature lubricating
ability - much better than petroleum and many other synthetics -
providing less smoke, and clean spark plugs, pistons, and power
valves. These basestocks are combined with low-ash deposit control
and anti-scuff additives to prevent ring-sticking and scuffing under
extreme temperatures and keep the piston and exhaust ports clean.
The slipperiness of Red Line Smokeless Oil can produce more
power and can provide significantly longer bearing life than when
using manufacturer’s oils or other synthetics, even in oxygenated
gasolines. The low-ash chemistry provides better cleanliness in
higher temperature air-cooled engines. The thermal stability graph
shows the Smokeless providing better cleanliness than petroleum
lubricants and it also provides significantly better scuff protection,
but for significantly improved power production any of the other Red
Line two-cycle lubricants are superior. This lubricant also has excellent
high temperature stability - much more stable than petroleum or
other types of synthetics - providing less smoke, and cleaner spark
plugs. Recommended for high-performance stock or slightly
modified engines and where ISO GD, JASO FC, or API TC lubricants
are recommended, but is not designed for outboard use.
Two-Cycle Alcohol Premix - contains the same lubricating properties
as Red Line Two-Stroke Racing Oil, but does not contain the
detergents designed for gasoline engine cleanliness. Due to the
clean-burning properties of methanol, the cleanliness in a methanolburning
engine would be comparable to the Two-Stroke Racing Oil.
Two-Cycle Alcohol Premix is generally used at leaner fuel
il
mixtures than used in gasoline engines because of the greater
fuel:air ratios used with methanol. This is an excellent product for
model engines which use alcohol/nitro fuels, providing excellent
cleanliness and wear protection.
New Ring Seating - Red Line Two-Stroke Racing Oil generally
should not be used to seat a new ring because of the extreme
slipperiness of the lubricant. A petroleum two-cycle lubricant used at
normal loads for 15 minutes should be adequate for ring seating.
Red Line Two-Stroke Oils can be used for ring seat if the engine is
operated at 80% load for 15 minutes immediately after start up. Red
Line is compatible with petroleum lubricants, so system flushing is not
necessary.
Compatibility - Red Line Two-Cycle lubricants are compatible with
petroleum, castor and most synthetic lubricants. They may be mixed
together in concentrated form or the fuel without separation or gel
formation.
Rust Prevention - all Red Line Two-Cycle lubricants are designed to
provide greater rust protection than required for BIA certification. The
rust protection in Red Line two-cycle lubricants make them suitable for
fresh-water or marine use.
Biodegradability - the synthetic lubricants used in Red Line products
are more biodegradable than petroleum-based lubricants.
Fuel Stability - Red Line Two-Cycle lubricants will dissolve in
gasoline at ratios of at least 15:1 and will not separate in even freezing
conditions. Red Line Two-Cycle Alcohol is soluble in methanol at
ratios of up to 5:1 at 70°F and 15:1 at 32°F. Red Line Two-Cycle lubricants
will help stabilize fuels and prevent rust for seasonal storage.
Mix Ratios - proper mix ratios should be determined by the engine
builder for the application being considered. Choosing the proper ratio
depends on bearing and piston design, piston clearance, rpms, and
air:fuel ratio. Higher rpm engines and those operating at high cylinder
head temperatures require more oil in the fuel to maintain proper lubrication.
When switching to Red Line Oil, begin with the same ratio at
which other lubricants have operated successfully. Red Line Two-
Cycle lubricants will allow the leanest oil:fuel ratio of any product on
the market. If other lubricants have successfully operated at, for
example, 100:1, then the Red Line lubricant for that application can
also be used at the same ratio. After reviewing the performance at a
given ratio, the amount of oil can be reduced slightly, to determine
whether the reduced ratio is satisfactory or whether additional
decreases can be achieved. A significant advantage of the Red Line
Two-Cycle lubricants is that rich fuelil mixtures can be used without
significantly altering the combustion characteristics of the fuel and still
provide excellent throttle response. As a starting point, the Two-Cycle
Kart Oil is generally operated at ratios between 16:1 to 32:1. The Two-
Stroke Racing Oil is used at mixtures of 24:1 to 32:1 for 9,500 rpm
outboard race motors, 50:1 for high-output operation, and up to 100:1
if the engine is properly designed for reduced oil mixtures. The Two-
Stroke Watercraft Oil, Two-Stroke AllSport™, and Two-Stroke
Smokeless can also be operated at ratios between 24:1 and 100:1,
depending on the designed lubricating requirement.
Summary of Two-Cycle Recommendations
Two-Stroke Racing Oil / Two-Cycle Kart Oil (they are both the same
chemistry) - for highly modified racing engines which turn high rpms,
such as racing motorcycles, karts, personal watercraft, snowmobiles,
and highly modified outboards.
Two-Stroke Watercraft Oil - for stock to moderately modified
outboards and personal watercraft where NMMA TC-W3 or any TCW
lubricant or other ashless lubricant is recommended.
Two-Stroke AllSport™ Oil - for stock to moderately modified motorcycles,
snowmobiles, garden equipment and chainsaws or any twocycle
engine which recommends a low-ash type of lubricant.
Two-Stroke Smokeless - for stock two-cycle equipment which
requires low-ash chemistry and there is a desire to completely eliminate
smoke.
Two-Stroke Snowmobile - for stock to moderately modified snowmobiles
which require very low-temperature pumpability.
