how many gallons??

[deadtofall_11]

according to my owners manual on my 84 cutlass calais i have a 18 gallon fuel tank, but i ran it almost to empty and then filled it up and it only took 14 gallons.
did some have smaller tanks or what???

"almost empty" can mean anything. You don't have a 14 gallon tank.

The gas gauges are notoriously inaccurate, especially after 30 years...

Run it completely out and then fill it up :lol: She'll take 18 gallons

Thats pretty good in my SS i have only put 11 gallons in max I know theres plenty of fuel but when the guage is reading empty I stop ... the nice thing is I average $35. at the pump 😀 .. unlike my truck thats upwards of average $60. and thats not empty...
You could always put a gallon fuel jug in the trunk and drive around till you run out then dump in your 1 gallon and head to the gas station, but chances are the manual is right 18 sounds bout right

What you learned from that is, when your guage points to E you (probably) have about 4 gallons left.

I just bought my oem gas tank here in canada and its 61L which is like 20G more or less, nest the gas guage is know to be wrong i seen this myself on my car, where it says near empty and only take about 40L or so. So the gas tank takes about 61L(20G more or less)

61 litres is 16.11 US gallons

I think when I bought my grand national tank for the tpi install, it said it was 17 gallons.
