VP 50 - 1 Premixed Small Engine Fuel is a 94 octane, ethanol-free fuel for 2-cycle engines. It is ready to use and features the perfect oil and gas mix ratio, so it saves you time. Above all, we engineer our small engine fuels from higher-grade base stocks and include only the best components available. As a result, you're ensured of getting an exceptionally clean-burning 50 - 1 fuel. We design it specifically for 2-cycle gas powered engines in outdoor power equipment that require a 50 - 1 gas-oil mix. These engines run hotter and demand better care and maintenance. Furthermore, the lubricant package in our 50 - 1 fuel mix meets or exceeds JASO FD, ISO-L-EGD, and API TC standards, as well as all manufacturers' specs, including Stihl, Husqvarna, Echo, Maruyama, Shindaiwa, and more.
