I get low fuel warning and i fill up so far the max i have filled up is 15.5 gallons. The tank on the car is suppose to be 18 Gallons so who here has pumped the most gas in their car at one time?

I managed 17.6 once.... never again.

Running on fumes is bad for the pump.

Do we know if the Tank is exactly 18 Gallons? or is it a little larger?

it's aprox 18.25 Gallons.

it's slightly enlarged over the regular CTS Tank around the fuel pump (I presume to ensure it's submerged during higher-g cornering). That's the 'reason' why we don't have folding rear seats.

I just looked through my fuel economy worksheets from the last 3 1/2 years. I did 17.5 gallons once last year. Never again. On average, I'm filling up with 15-16 gallons.

No idea here. I just fill up when it gets to 1/4 tank.

17.2 had my finger on the On Star button. Didn't think I was gonna make it.

When the fuel range indicated 40 miles left (under 40 miles doesn't display) took 15.8 gallons which would be about right for an 18 gallon tank with my fuel economy.

I have gotten to 17 gallons once but I thought I noticed a bit of stuttering from the car so I won't ever be doing that again. I usually refuel at about 15 gallons now. But gosh does the fuel meter drop fast.

17.04 gallons. That was a hairy, no-throttle coasting as much as possible trip to the gas station. :) My average fillup is in the 15 gal range.

Consistently 15.2 I always fill up right when my low fuel warning turns on.

Gen 1 srx had a 20 gallon tank. Since they are both sigma chassis I wonder if a srx tank would fit?

When the light hits I fill it takes 15.2 gallons. I heard 18/4 tank that's about 23 Olnes reserve on the light I would assume I would never take it that far.

That is a mess sorry fill at lite on takes 15.2. If tank is 18.25 that leaves a 3 gallon reserve ?? I always fill ASAP when lite hits. I really don't like to go that far down . I have not looked into yet the filter is outside tank a serviceable? My Dodge Magnum hemi 5.7 had NS filter in tank as well as my Ram 1500 . I would always try to fill at 1/4 tank. Where is coupe v 2012 filter ? 3 gallons left when lite comes on , cool 1 mo

18.1 once, and the car ran fine, but I was very nervous, and barely found a station open. I suspect some stations overcharge by inflating the volume a bit, though. I usually fill up close to when the warning comes on, and it usually takes 15.5 to 16 gallons then. My '08 CTS would take 14 gallons under the same circumstances, with pretty much the same tank. That was annoying.

I've gotten 17.6 a couple of times.

When the low fuel light comes on, you have (almost) exactly 2 gallons left. At my highway useage of close to 20 MPG, I know I've got about 40 miles to find a gas station before it's lights out.

Sorry, the instant fuel Mileage When you really put your foot into it it goes right to zero, well at least I had it down to four once.
