In this study, a methodology to measure fuel consumption for light duty vehicles (LDV) in Colombia was elaborated based on existing methodologies from road transportation worldwide. This methodology was proposed as a tool for the evaluation of energy efficiency strategies applied to vehicles, as well as establishing the baseline for measurement, control, and regulation of consumption of fossil fuels based on metrological criteria. Additionally, the capacities for measurement within Colombia were analyzed, and procedures stated by the Code of Federal Regulations of the United States of America were adopted for measuring fuel consumption of LDV by gravimetric methods. An uncertainty model based on the Guide to the expression of Uncertainty in Measurement (GUM) was elaborated, and the contribution of different variables associated to the measurement process the instruments, the equipment, and the ambient conditions over the uncertainty of the measurand, were analyzed. Resumen En este trabajo, se elaboró una metodología para medir el consumo de combustible para vehículos livianos (LDV) en Colombia, basándose en las metodologías existentes para el transporte por carretera en todo el mundo. Esta metodología se propuso como una herramienta para la evaluación de estrategias de eficiencia energética aplicadas en vehículos, así como para establecer la línea base para medición, control y regulación del consumo de combustibles fósiles con base en criterios metrológicos. Además, se analizaron las capacidades de medición dentro de Colombia y se adoptaron los procedimientos establecidos por el Código de Regulaciones Federales de los Estados Unidos de América, para medir el consumo de combustible de LDV por métodos gravimétricos. Se elaboró un modelo de incertidumbre basado en la Guía para la expresión de la incertidumbre en la medición (GUM), y se analizó la contribución de diferentes variables asociadas al proceso de medición, instrumentos, equipos y condiciones ambientales sobre la incertidumbre del mensurando.
