The Fuel
Use the Right Fuel
It’s imperative that you use the correct fuel in your
TRX 2.5R Racing Engine for maximum performance
and engine life. Traxxas Top Fuel
™
should be used to
ensure correct engine lubrication, performance, and
ease of tuning. Traxxas Top Fuel has been proven in
thousands of engines, so you can count on it every day
for great performance.
Top Fuel is the only fuel which is 100% certified for use in Traxxas
engines.
Traxxas Top Fuel is made with just the right balance of the highest
grade natural and synthetic lubricants to allow excellent throttle
response and the best top-end performance, without sacrificing
long-term durability.
All of the components in the fuel are carefully selected from the best
materials available and then custom blended to match the
metallurgy and temperature characteristics of Traxxas engines.
You may use 10% or 20% nitro-content fuel. Use the same percentage
all the time; don’t switch back and forth between 10% and 20% fuel. If
you break-in your engine on 20% fuel, then always use 20% fuel.
What about Other Fuels?
Can other brands of fuel be used besides Top Fuel? There are other
fuels that can provide satisfactory performance; however there could
be long-term costs in the form of decreased engine performance, loss
of tuning ease, and shorter engine life. Only use fuels that contain both
castor and synthetic oil.
Everyone has an opinion or a claim to make about fuel. The engineering
team at Traxxas spent over 2-years developing the TRX 2.5R Racing
Engine. No one knows more about the specific fuel requirements of
Traxxas engines, than Traxxas engineers. We strongly urge you not to
take chances with your engine investment and use the Traxxas fuel
made for the TRX 2.5R Racing Engine.
Handling the Fuel
Follow all directions and warnings on the fuel can.
Keep the fuel tightly capped at all times. Some components in the
fuel can evaporate very quickly and upset the balance of the fuel.
Do not store unused fuel in the fuel dispenser. Immediately return
fresh unused fuel back into the fuel can.
Do not mix old and new fuel. Never mix different brands of fuel
together.
Store the fuel in a cool dry location, away from any source of heat,
ignition, or combustion.
Read and follow the safety precautions on page 4 in this
manual.
Filling the Fuel Tank
Use a fuel dispensing bottle (Traxxas Top Fueler, part
#5001) to put fuel into Revo’s fuel
tank. To fill the fuel bottle, squeeze
the air out, insert the dispenser tip
into the fuel can, and release your
grip on the bottle. As the bottle
expands, fuel will be drawn into it.
To fill your model, pull up on the
fuel cap handle, insert the tip of the
fuel bottle, and squeeze to dispense
the fuel.
DANGER! Model engine fuel
is poisonous to humans
and animals. Drinking the
fuel can cause blindness
and death. Handle with
care and respect. Keep it
out of reach of small
children at all times! While
driving, do not leave your
fuel dispensing bottle on
the ground where a child
could have access to it.
Follow fuel label warnings.
You may use higher nitro
percentages than 20% in
certain circumstances. Call
1-888-TRAXXAS for more
information.
