91 PA Gas Tank

Hey i just purchased a 91 PA and it didnt come with the manual. I havent driven it enough or had the gas tank low enough to find out how many gallons it holds... can anyone let me know???

My 92 PA has 18 gal capacity. I assume the 91 is the same since they are nearly identical cars.

18 gallons on my 91. I have a non-supercharged ultra.

I just did a fuel economy check. Im getting 20mpg (about 50 miles driven in city, 200 driven on hwy), not too bad. I think its rated at 19/27. 92000 miles and a terribly worn out suspension (which im fixing)
