Where can i find the speed vs milage curve or RPM vs milage curve for honda CIVIC VTEC?















What is the optimum speed for honda civic to get best milage?

Any vehicle under the speed of an approximation to your local gravity gravity constant times ten or approximately 98Km/hour or 55M/hour is a good rule of thumb for any vehicle. Given the coefficient of drag is also a factor you need to reduce that speed to about 80km/hour or 45M/hour on most vehicles but in your particular vehicle the coefficient of drag will bring you to about 95km/hour or around 50M/hour. Also remember that there are other things that in reality will determine when you are getting the best mileage, per example the fuel you put on it could change slightly to reduce your mileage about 5 to 10 percent, only way to know this is to take a sample each time you fill up, and that will give you the speed you would require at that particular time. However if you use the rule of thumb I mentioned above the fuel difference is negligible. Fuel efficiency is mainly how much power you can output with the minimum amount of energy, this means if you take it easy on your gas pedal you will gain efficiency at the cost of time. As you will see on traffic signaling you cannot drive faster than the speed limit to catch more than tree lights in green an equal distance apart, this is not coincidence is actually calculated, to maintain efficient traffic flow. GOOD LUCK and have fun with your car...

55MPH for almost any vehicle is best MPG

55 or whatever your manual tells you. or just stay at or below 2200 rpm.

My 2001 Civic doesn't have a VTEC, but from personal experience, I can tell you that as long as you stay around 55-60, you should do great. Mine just got 37MPG on a trip I took last weekend, and the car has 75,000 miles on it since I bought it new. Road conditions as well as weather and terrain will play into it as well. Going thru the mountains on PA, the car dropped off to 27, but when I was on the Carolina coast, it jumped up over 35.
