How many gallons in a stock gas tank?

[turbowrenchhead]

I was wondering how many gallons are in a stock 87 gas tank?

18.1 rings a bell

Correct 18.1

For those who have trouble with numbers (like me),
that's eighteen and one-tenth gallons.

Yes, I have too much time on my hands today, waiting to leave for BG!

Of course if you have a digital dash car you have no earthly idea from one minute to the other how much is in the tank. Thanks GM!
