How many miles to a gallon does my car have?

I have a 2004 Honda Civic LX. It's a pre-owned sedan-style. Not sure what engine it has. I think it has about 10-11 gallons in it.

I'd say, 30 or better if it's well tuned. My daughter drove one of those for years and enjoyed great gas mileage. Hmm… Is it red? 20-30 If your Civic has a 1.7 L engine your should expect approximately 25 city and 35 highway. If you have a 2.0 L you are looking at slightly less.

MPG not only will depend on engine displacement (size) but also the type of transmission. Here's all your options.

http://1.usa.gov/24ukf9e It will get somewhere between 26 mpg city and 51 mpg highway. The broad range is because the car could have any of five different engines and three different transmissions. In addition a hybrid model was available.

You need to know these things. Raise the hood and look for an engine identification sticker. The transmission should be obvious. I'll go out on a limb and guess that it it the automatic (as opposed to the 5 speed manual or the two speed CVT with overdrive)

Once you find these things out, you can look it up on such sites as Edmunds dot com and fueleconomy dot gov.

Without this information, any answer which states an actual number is pure guesswork.

You can also figure out the "real world" gas mileage by simply writing down simple facts:
How much gas did you buy in gallons (or liters) and what was the gas gauge needle and odometer setting. Then when the gas gauge needle points at the same spot subtract the odometer number and that will tell you how far you traveled on that amount of gas. Divide that number by the amount of gas and you have your gas mileage. Next time you fill it up, reset teh trip odometer and see how many miles you go when you fill up next - divide by the # of gallons on that 2nd fillup - probably 27-33 overall, maybe up to 38 hiway probably around 30 mpg, factoring in the wear and tear. You gotta remember that your car is 12 years old. I just bought a very high miles 2003 Civic LX, automatic and it gets about 38 highway. Amazing car. The 7th generation (2001- 2005) is a big improvement over the 6th generation.

20-30
