BOOSTane Marine Octane Booster offers the ability to increase octane levels up to 116 and is specially formulated to complement marine engines. It provides all the advantages of BOOSTane Professional and can help owners concerned with phase separation of their fuel. BOOSTane's Marine formula is the team getting back to its roots. The original, innovative formula was designed for demand in the offshore powerboat racing arena. With BOOSTane Professional at its core, Marine still has the proprietary carrier and octane enhancing capabilities that separated itself from the competition. However, focusing on issues that are more pertinent to marine engines—such as fuel stability and lubrication—BOOSTane Marine's formula gives the added protection that these increasingly higher performance engines need. Too many OEM companies require octane higher than what is available at the marina, and are still susceptible to the negative side effects of ethanol. Take full advantage of your summers on the water and let BOOSTane restore your boat's full potential. Turn the pump gas in your boat or PWF tank to a high performance race fuel equivalent! Additional notes: * Increased lubricity for engine internals, valves, and seats * Ethanol stabilization for prolonged storage with fuel still in tank * Will raise your effective octane fuel number 23 numbers * Don't get stuck with 90 octane at the marina again * Use the BOOSTane App to blend exactly to your necessary specifications * Safe for use with catalytic converters and oxygen sensors * Won't settle out of solution and become ineffective in your tank, due to our proprietary carriers * Protect against phase separation and water in your tank from prolonged storage and ethanol * Works in all internal combustion engines, from powerboats and high performance fishing boats to personal watercraft and leisure * Naturally aspirated or forced induction, your peace of mind is here * LOWER Compression Engines and 2 Stroke * Proprietary chelated carrier * Anti-corrosion against ethanol * Cleaning agents * Anti-carbon buildup * Not street legal * Available individually or in larger quantities
