The VRO (Variable Ratio Oil) system is an oil injection system used in some Johnson outboard motors, designed to automatically mix oil with fuel for two-stroke engines. This system adjusts the oil-to-fuel ratio based on the engine's RPM, providing more oil at lower speeds and less at higher speeds, which helps to reduce smoke and improve performance. The VRO system is often praised for its convenience, as it eliminates the need for manual mixing of oil and fuel, but it requires regular maintenance to ensure reliability. Many users opt to bypass the VRO system in favor of pre-mixing for added peace of mind.
