This is a straightforward guide backed by real products from National Aviation to help you choose the right oil. Unlike automotive engine oil, aviation oil must perform under extreme temperature swings, from a cold hangar start at -20° F to operating temperatures that can exceed 240° F, at altitudes where atmospheric pressure drops significantly. It must resist oxidation, prevent corrosion from moisture and combustion acids, suspend lead by-products from avgas, and maintain stable viscosity from the first second of engine start.
