I recently purchased a used 1999 Honda Civic DX is what it says it is but it's a 4 door... maybe something is labeled wrong? Anyhow, just wanted to ask if anyone knows how many gallons the gas tank holds. I have the original book but it doesn't tell you anywhere in it how many gallons the car will hold. I am now sitting on the red and I haven't seen a gas light come on and I've gone 313 miles on the last fill up.. I only want to make sure I can drive 3 more miles to gas it up without running out! Can anyone help?? I don't know if I even have a reserve light in the car! I've only had it for a week... Thank you for your help...

13 gallons.
