I dont think there is a connection between an oil change and the gallons per mile.
With that age car, I suggest a Terra engine clean. It will blow away nine years of gunk from the spark plugs, fuel injectors, cylinders and exhaust. Should give you more power, more miles..

First question is yes bad or worn plugs can burn more gas to generate the same amount of power.
Second question, you could fill up the tank and record the mileage, then fill it up again when it measures half a tank and compare.
If the gas gauge is working correctly it should take half the total number of gallons the tank holds to fill it up again. And the miles you drove divided by the number of gallons used equals your gas mileage.

it is within factory specs to burn more than a quart of oil within 2500 miles it is also common with oil changes are done at small and quick oil change places that the oil is not filled to the max level making it look like it burns more than it does and not using synthetic oil as required asl makes a difference

Find the cause of the check eng light and find the cause of the poor mileage.

I think u need to replace "air mass sensor" normally when it's broken cars taking lots of gas

could be a leak. (look for gas puddles under your vehicle daily & have your oil pan drained to check for gas inthe oil pan)
could be your fuel mixture is to rich burning to much fuel0.
could be someone is stealing gas from your tank. (get a key lock on your gas cap if you dont have one yet.)
could be your driving more then you normally do. (monitor your miles driven versus how much gas you burn and figure out your miles per gallon to see if it is off something drastic)

You probably have a submersable pump. If you have run the gas on below 1/4 tank for some time, you probably burned out the pump. Alway fill up 1/2 tank or more.

And with the mileage, it isn't unusual to replace the pump.

to see what you get for mileage, take it to a gas station and fill it till the pump stops and reset your trip meter. Drive it around like you normally would to work or whatever till the tank is almost empty and go fill it up again till the pump stops. Its best to go to the same pump you used before. Once it is full look to see how many gallons or liters you put in(This is how many you used since the last time you filled up). Take the number of miles/kilometers from your trip meter(the number of miles/kilometers you drove since you last filled up) and divide it by the gallons/liters you used and you will get your miles/kilometers per gallon/liter. Compare this with the rating your vehicle is suppose to get. But remember it can very depending on how you drive.
Miles/kilometers divided by gallons/liters

They say that that is normal to burn some oil. I use Moble 1 full synethic oil, and it quit using oil, because synethic will not burn.
