Sometimes marine engines require higher-octane gasoline than what is typically available at marinas and gas stations.
Specially formulated for high-performance marine engines, new Octane Boost from ValvTect Petroleum Products increases the octane number by two numbers, or 20 points, according to the manufacturer. Octane Boost is an EPA-approved additive that contains MMT and can be used in all 2- and 4-cycle marine engines. It also contains a gasoline detergent, which the company says cleans up and prevents injector, intake-valve and fuel-system deposits to maximize power and performance. MSRP is $19.99 for 32 ounces.
