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.
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.
Everyone has an opinion or a claim to make about fuel. The
engineering team at Traxxas spent over 2-years developing the
TRX 2.5 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 2.5.

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.
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 5 in this manual.
Filling the Fuel Tank
Use a fuel dispensing bottle (Traxxas Top
Fueler, part# 5001) to put fuel into the Nitro
4-Tec'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 flip up the
spring-loaded cap on the fuel
tank, insert the tip of the fuel
bottle, and squeeze to
dispense the fuel. Fill the tank
until the fuel level reaches the base of the filler neck. Close the
fuel tank lid, making sure it closes tightly.
