Amsoil completed a test in compliance with the industry standard SAE J1321 (TMC RP-1102) In-Sevice Fuel ConsumptionTest Procedure demonstates use of Amsoil synthetic lubricants can increase fuel economy in short to medium haul diesel applications and in the case did by 6.54 percent. The study was designed to eliminate enviromental and operating variables as much as possible by using two nearly identical trucks and operating them in a consistent and methodical fashion throughout the same test route. Following the baseline segment data indicate the test vehicle operating with conventional lubricants in its engine, transmission and front and rear differentials consumed more fuel than the control vehicle operating with the same lubricants. After a thorough lubricant flush and installation of Amsoil synthetic lubricans, data collected during the test segment indicate the test vehicle consumbed less fuel than it did during the baseline segment. Calculations direived from the data sets confirm a 6.54 percent fuel economy improvement provided by Amsoil synthetic lubricants. The fuel economy improvement directly correlates to reduced fuel costs and reduced exhaust emissions as well.
