All manuals spec 15.5 gallons total capacity, though you will never get it completely empty.
If the plugs have never been changed, yes it could cause bad gas milage ue to a bad burn of fuel. This will also eventually lead to you cat converter being pluged, also causing bad gas milage, and will toast you O2 sensor, cause extremely bad gas milage.

86 Trans Am w/ built 355TPI with SLP goodies and too much other stuff to List. One sweet *** car, wish I would have had a good enough Job to pay insurance on three cars so I could keep it, but for a 89 Turbo Trans Am w/ Low miles, I think I made the right choice!

the left side isnt that hard, you can get the first 2 from the top, then for the last 2, jack it up, and get em from the bottom
