1985 Isuzu I-Mark
Fuel Economy Overview
The 1985 Isuzu I-Mark achieves an EPA-estimated 22 MPG in combined city and highway driving, with 21 MPG in the city and 23 MPG on the highway. Powered by a 1.8L 4-cylinder engine paired with a automatic 3-spd, this subcompact cars features Rear-Wheel Drive drive.
In terms of environmental impact, the 1985 I-Mark produces approximately 404 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 I-Mark has higher-than-average emissions in this regard.
The estimated annual fuel cost for this vehicle is $2,700, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $2,750 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.

Adjust the slider to match your daily driving habits. City driving involves stop-and-go traffic under 45mph, while highway driving represents sustained speeds over 55mph.
Aerodynamic Speed Penalty
EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Expect your real-world highway fuel economy to drop by roughly 15-20% at interstate speeds.

Recall Intelligence
VEHICLE MAY EXPERIENCE PERFORATION OF THE FUEL PUMP DIAPHRAGM. EXCESSIVE ALCOHOL CONTENT IN THE FUEL PROMOTES DEGRADATION OF THE DIAPHRAGM COATING RESULTING IN RADIAL CRACKING OF THE DIAPHRAGM.
Consequence & Remedy
Consequence: A PERFORATED DIAPHRAGM CAN ALLOW FUEL TO LEAK FROM THEFUEL PUMP INTO THE UNDERHOOD AREA. THIS COULD ULTIMATELY RESULT IN ANUNDERHOOD FIRE WITHOUT PRIOR WARNING. SUCH A FIRE COULD SPREAD TO THEPASSENGER COMPARTMENT.
Remedy: A FUEL VENTALATION HOSE KIT WILL BE INSTALLED TO PREVENT FUEL FROM ESCAPING INTO THE ENGINE COMPARTMENT IF THE FUEL PUMP DIAPHRAGM LEAKS AND THEREBY REDUCE THE POSSIBILITY OF AN UNDERHOOD FIRE.
