I have a 1995 Honda Civic Auto 1.6L VTEC. What speed would give me the best mileage? I've heard anywhere from 45-55 as typical and some rare exceptions at 65. At 65, I get 2500 RPM, 60 MPH = 2400 RPM, 55 MPH = 2200 RPM, 50 MPH = 2000 RPM. I've been slowly accelerating and noticed if you push on the gas pedal too hard, the car will shift up to 3000 RPM (probably when VTEC kicks in). Likewise, less than 2000 RPM doesn't seem ideal if you step on the gas pedal too slowly. I've been trying to keep it between 2000-2500 RPM. Since the car can't use a ScanGauge, I've had to guess at what works.
