poor gas mileage

[dat2010]

i have a 1990 honda accord ex 4dr thats getting terrible gas mileage. CEL is not coming on. i'm going through have a tank in two days. bought it used with an oil leak; but replaced the motor with a motor with 108,000.00 miles on it. didn't change plugs wires or cap rotor button or wires or air filter or fuel filte. what would you suggest i replace first or in what order should i replace things.

Air and Fuel filter no doubt...

What is your mileage like per tank?

Is my gas mileage bad…

I own a 91 Accord Ex that’s stock. Everytime i’m at the gas station, i make sure to fill the whole tank and to reset the odometer ‘’Almost 15.5 gallons” it usually gives me around 220-250 miles for the whole tank. I’m i getting good mileage on my car???

thats roughly about 402.33600 kilometers

i wouldn't think its THAT bad... however can be better.

general maintenance would definitely benefit you, proper tires, and so forth.

I would visually inspect everything first. Cap and rotor are all easy to take off and check, so are the spark plugs and air filter. Plug wires you'd need a multimeter to check resistance but not everyone has one. Fuel filter I change every 15,000miles/25,000kms which for me is once a year and most times I pick up a used car, it looks like it's been never changed.

Another thing to consider is if it's got high mileage and the O2 sensor is still original, good chance it's tired and you'd benefit from a new one (NTK or Denso only). The CEL will usually not come on even if it's time to change it.

i get little over 400 miles with a full tank...

also check your tires too for proper psi . most people over look this .

lol...

first tank on my cb7 right now... half tank and 350km...

^^^ im guessing that's highway km.....cause for me like driving in the city, where you stop, go , stop go.....350km is one tank lmao lmao

[YK86]

Wow, that must be like 100% city lol. I do roughly 70% highway driving but I was getting 550kms per 55L and after the 5 speed swap/converting from f22a4 to f22a6, I get about 600kms per 55L.

I normally fill up at about 330-350 miles, and thats about 12.5-13.5 gallons. Which averages to just around 25mpg, which is what the combined city/hwy milage is for our cars if i'm not mistaken.
