There are a lot of factors that can have an affect on fuel mileage. Weather conditions, driving patterns, fuel quality, condition of engine tune up items, compromised oxygen sensors, failed sensors, dirty fuel injectors, or any number of other possible conditions will have a direct effect on fuel consumption. Also, a vehicle can lose some of its ability to get optimum fuel economy over time, as it ages. Wear on an engine will tend to lose some fuel economy, and can also lose some of its power.
