Just wondering what kind of gas mileage everyone gets?

I get about 450Km on a tank on my 1990 with 5 speed.

16.5 mpg. thats about 200 miles on 12.5 gallons of permium. I reset the tripmeter everytime i fill up, then the next time i fill up i know exactly how many miles I have driven and can figure out mpg. Anyway i still have a rough idle problem and my milage sucks, not sure why (new injectors 30k ago, new plugs, o2, cap, rotor, clean aiv, iaa, throttle body etc.)

Umm, well the s13 and s14 have different size tanks so keep that in mind when you read/post. By tank i mean from full, to reading empty on the gauge, but even so this leaves about 2 more gallons in the tank for "emergencys." The sohc will probably never get 300 mi to the "tank."

Yeah, I'm with HaveBlue. I am LUCKY to get 16 in my 90 5-speed. There are no mods except some exhaust thing that was there when I bought it. It's louder than hell is all I know. Could the SeaFoam treatment possibly help with this?? I can't figure how a 4 cyl. could only get 16 a shot.

On my 1995 I used to get 25-26 consistently and about 28 on long trips. Once drove from Austin to Lubbock and got like 420 miles on my tank with atleast a gallon left over. That felt good :)

Now I have a 1989. I've only had it for 15.5 hrs now so I have no idea what kind of fuel economy I get. Does anyone know how big the tank is?
