VP's 15% Air is an affordable nitro fuel for two- and four-cycle sport flying. It includes a high-performance oil package (80% multi-viscosity synthetic & 20% castor), providing exceptional gains in power and RPMs. You'll appreciate the DOT-approved pressure-tested metal can and inner lining, which prevents corrosion. We even use strict standards to test the closure cap. Why? Because we want you to have premium fuel in a fully sealed can that delivers the same quality and performance months down the road as when you purchased it.
