Most Paramotors utilize 2-stroke motors, with a fuel-to-oil mix. We always recommend using premium unleaded fuel (ethanol free if possible), and high-quality synthetic 2-stroke motor oil. Always refer to your engine manual or manufacturer for the exact fuel-to-oil mix. Many European Paramotors require the use of “aviation fuel,” which can be very expensive and hard to come by. If a Paramotor engine is designed and built properly, it should easily run on high-octane auto fuel. You should be able to purchase fuel anywhere, instead of having to locate an airport.
