Three types of QMI after-market additives were evaluated to determine their effects on the properties of military products. The additives were 1 a fuel additive, 2 an engine oil additive, and 3 a gear oil additive. The major adverse effects observed were that the QMI engine oil additive reduced the viscosity of Military engine oil, and reduced the Flash Point. Low temperature properties of the engine oil were slightly improved. The QMI gear oil additive produced the following adverse effects decreased the Flash Point of the gear oil and increased low temperature viscosity and foaming characteristics. The QMI fuel additive was blended in JP-8 with the following adverse effects reduced Cetane Number, and reduced water separation tendencies. Fuel lubricity was improved for ground vehicle applications, and a slight improvement 2 in fuel economy was measured with the additive in JP-8. PM and NOx exhaust emissions from a diesel engine were unchanged with the QMI fuel additive present. Finally, with the QMI fuel additive present, diesel engine piston deposits were increased in the Caterpillar Cat 1K1N test.
