Fuel Economy Overview

The 1991 Oldsmobile Silhouette 2WD achieves an EPA-estimated 18 MPG in combined city and highway driving, with 16 MPG in the city and 21 MPG on the highway. Powered by a 3.1L 6-cylinder engine paired with a automatic 3-spd, this special purpose vehicles features Front-Wheel Drive drive.

In terms of environmental impact, the 1991 Silhouette 2WD produces approximately 494 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this Silhouette 2WD has higher-than-average emissions in this regard.

The estimated annual fuel cost for this vehicle is $3,300, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $5,750 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.
