Fuel Economy Overview

The 1984 Honda Civic achieves an EPA-estimated 33 MPG in combined city and highway driving, with 31 MPG in the city and 37 MPG on the highway. Powered by a 1.3L 4-cylinder engine paired with a manual 4-spd, this subcompact cars .

In terms of environmental impact, the 1984 Civic produces approximately 269 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 Civic performs better than the national average in this regard.

The estimated annual fuel cost for this vehicle is $1,800, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would spend $1,750 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.

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.

critical
Component: FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP

UNDER CERTAIN CONDITIONS, MECHANICAL FUEL PUMPS MAY DEVELOP FUEL LEAKAGE AT CRIMPED SEAM BETWEEN THE TWO FUEL PUMP HALVES.

Consequence & Remedy

Consequence: FUEL LEAKAGE IN THE ENGINE COMPARTMENT CREATES APOSSIBILITY OF A FIRE.

Remedy: INSTALL AN IMPROVED FUEL PUMP ASSEMBLY.

advisory
Component: POWER TRAIN:DRIVELINE:DRIVESHAFT

LEFT DRIVE SHAFT MAY DEVELOP CRACKS, AND MAY BREAK UNDER HEAVY LOADING SUCH AS THAT CAUSED BY RAPID ACCELERATION. THIS DEFECT ORIGINATED IN A MANUFACTURING PROCESS WHICH HAS NOW BEEN IMPROVED.

Consequence & Remedy

Consequence:

Remedy: DEALERS WILL REPLACE THE LEFT DRIVE SHAFT ON VEHICLES THAT HAVE NOT BEEN PREVIOUSLY CORRECTED, AT NO CHARGE.
