I googled and i think these vehicles have a 16.6g gas tank. On the dash, my gas was pointed at empty, and i filled up but it only took 13.4g. So is my guage wrong/inaccurate?

another quick question, do these vehicles let you know when you have low gas or do i just have to look at the guage?

if it's a 3.1L it's got a 16.1gal tank, I bet it's a 3.8L which has a 17.1gal tank. No, there is not indicator for low fuel except for the guage. Don't wait for a light to flash, or you will run out of fuel

because these cars use a float, the amount of fuel needed to fill the tank will vary.

edit: the above information was found in the haynes repair manual, however according to the owner's manual, the capacity is 16.6 gallons.

i have the 3.8l v6


so what happened to the other 3 gallons? was there actually 3 gallons in there before i filled it up?


should i keep in mind that everytime its pointed at empty (on a flat surface), theres approximately 3 more gallons inside?

On E some gages will still have " some" fuel left, varies in every vehicle, you shouldn't run it that low for the sake of fuel pump life anyway.

Here's something I've noticed with my '93 and '99 luminas. With the '99, once the pump stops, I can only add a small amount of gas. Also the needle on the guage doesn't go past F. However on the '93 I can add quite a bit of fuel after the pump has stopped and the gas guage will often go way past F. As a side note, I can tell a big difference in the gas mileage between the two. The '93 (3.1) gets better than the '99 (3.8) ...go figure!!!
