More Info from Go Kart Masters Garage

Today, gasoline can go bad in as few as a couple of weeks. Below are our recommendations and tips to keep your go-kart fuel fresh.

Safety First 

  • Follow all state laws regarding the handling of fuel
  • Keep all gasoline away from open flames and sparks
  • No one under the age of 16 should handle gasoline or gasoline containers
  • Only use approved containers for fuel
  • Before refueling, wait at least 5 minutes to allow engine to cool

Fuel Facts

  • Ethanol attracts moisture from the air
  • Ethanol evaporates much faster than gasoline which lowers octane levels
  • Modern engines are high compression and require high octane fuel

Tips and Advice

  • Use 90 Octane or Higher
  • Use 100% Gasoline for quicker starting and better performance
  • Do not buy more fuel than you can use up in 60 days
  • Keep fuel caps secured when not in use - Highly recommend No-Spill gas cans
  • Do not fill go-kart fuel tank with more fuel than needed because the tank is vented to the open air
  • Use a fuel additive regularly
    (Seafoam. Stabil. Follow instructions on additive’s container.)
  • ALWAYS use fuel stabilizer during long periods of storage (more than 2 weeks)
  • If storing for long periods of time, run the go kart out of fuel
    • TrailMaster Mini & Mid Go Karts: Turn off fuel. Run the engine until it stops.

    Great gas tank

    Perfect fit. Not junk like the other one I bought without a screw top. Need the screw on gas cap to not leak when bouncing around.

    Perfect Fit

    Posted by Kevin O. on Aug 1st 2016

    The exact tank I needed for my sons Trail Master Mid XRX. The old one developed a hole in it from vibration and this was the perfect factory replacement. Very easy to install.
