What fuel should I use for a petrol RC car?

A gasoline-powered RC car runs on regular gas, but not every type is suitable. In the Netherlands and Belgium, E10 gasoline is widely available these days, but it’s not the best choice for small two-stroke engines like those used in RC cars. It’s important to choose the right fuel to prevent engine problems and wear and tear.

Which gasoline is suitable?

  • Euro 98 E5: this is unleaded gasoline with up to 5% ethanol. It is most suitable for gasoline RC cars.
  • Avoid E10 gasoline: E10 contains up to 10% ethanol, which is bad for small two-stroke engines. It can cause corrosion, moisture absorption, and problems with rubber parts in the fuel lines.
  • Premium gasoline (98 or higher): can provide even better performance and protection, especially with powerful engines.

Mixing fuel with oil

A gasoline-powered RC car always uses a mixture of gasoline and 2-stroke oil. The ratio is usually 1:25, depending on the engine and manufacturer. Always consult your model’s manual for the correct ratio.

Tips for use

  • Always use fresh gasoline; do not let the mixture stand for months.
  • Shake the fuel can well before use so that oil and gasoline are completely mixed.
  • Store fuel in a cool, dry place in a tightly sealable jerry can.
  • Preferably use synthetic 2-stroke oil for optimal lubrication and less smoke.

Conclusion

For a gasoline-powered RC car, it’s best to use Euro 98 E5 or premium 98 gasoline in combination with high-quality 2-stroke oil. Avoid E10, as it can damage the engine and its components. This will keep your RC car reliable, powerful, and well-protected.
