Recently, I had only been able to get 200 miles out of a “tank” of gas which was stopping the gas pump at 10 gallons. I was filling at what showed as an 1/8th of a tank on the gauge so I figured it was relatively empty. However, I did some research and found out that the car in fact has a 16 gallon tank, that the fuel light comes on with under 3 gallons remaining, and that the pump usually shuts off early with these. To test out the shutting off early theory, I tried pumping the car all the way on the slow setting at the gas station. This got up to 11 gallons (from 200 miles with an 1/8 of a tank) but shortly thereafter it vomited much of that extra gallon out of the filler neck and made a mess. So no, the car actually was full when it stopped at normal speed!

Then this weekend I figured I would just drive the car until the fuel light came on (or I ran completely out of gas because it didnt work lol) but thankfully I was able to make it to work today with 290 miles on the trip meter and didnt run out of gas! The fuel light came on around the 270 mile mark, meaning I had probably about 1.5-2 gallons remaining when I filled it up which lines up with the 14.2 gallons I added to a 15.9 gallon tank. The odd thing though was the meter was under a quarter tank at 200 miles, under an 1/8th at about 240 and then just stayed in there until the light came on, was a little closer to the line, and then I made it. I assume that means the line actually is empty but man is that some dampening to go all the way to below a 1/4 like that!

Also, since this car is partially wrong wheel drive, I figured my Oppo name needed to change to reflect the torque split with DCCD set to Auto. Interestingly I can play with that to get up to 95% CORRECT wheel drive (RWD) but I have just wanted to just get used to Auto first since that is how I will leave it 99% of the time anyways.

I wish all car manufactures would use accurate gas gauges and have a agreed upon standard for the low fuel light. In my Tahoe, the light comes on around an eighth of a tank. If I wait until the gauge is on “E”, I can fit 20 gallons in. The manual says it has a 26 gallon tank.

I understand some “leighway”, especially if the car is a gas guzzler and 6 gallons could go in like less than 20 miles if you tried hard enough. But even in the STi I still get a solid 18-20 while driving like a madman so Ive got more than 50 miles to go with the fuel light on, and like 100 miles to go when it shows an 1/8th of a tank! If it was linear then I would get like 800 miles to the tank. I just would like to have a “gauge” of how much gas I have left, a rough estimate. Rather than it basically saying I have A LOT or A LITTLE.

My Miata will also just show E forever. It has no gas light so I guess that is the “light” coming on when its just solidly below the E mark. This is the one time I dislike an analog gauge and would just love a digital readout of the gallons remaining. Even newer cars that show “miles to E” are just annoying. I just want gallons to E and then I will figure out the rest.

My 15 F150 has a 36 gal tank and a numerical DTE. Unless I take a road trip, my tank lasts over 3 weeks / 550 + mi.

My Outback has a 16.9 gallon tank. Usually if the tank has been primarily used on the work commute the light will come on around 250 miles and it’ll take 13.5 gallons if I fill up when the light first went on. The furthest I’ve stretched a tank in terms of fuel used was 15.6 gallons, which got me 368 miles of highway driving.

The DCCD is fun to play with, especially in the winter! There is an issue with these cars where they don’t fill up all the way especially on pumps with the vapor lock recirculation thing. It’s a common issue I’ve seen posted on the forums.

Nice hawk eye ! My favor it 2 years...I’m slightly bias myself ;)

My Mustang has a stated gas tank capacity of 16 gallons. The low fuel warnings start at what the car believes is 50 Miles To Empty. I have run it down to 0 Miles To Empty and it took 15.4 gallons to fill it up - an alleged reserve of .6 gallons, or 14.5 miles @ 24.1 MPG. I went 371 miles on that tank. I have yet to run it until it quits, and see how many usable gallons the tank actually holds... but based on the data I’ve looked at over 18k miles, I’m comfortable with the fact that I can consistently run it down to 0 MTE without actually running out of gas.

I’ve always managed to get at least 50 miles after the light came on in any car that was my own. My old Element could do 80 miles or so before stuttering. The V10 Ram could do 100 miles if I was on the highway.

My grandpa’s 7ish Fords all had broken gas gauges, so “5 in the tank” were words to live by.

Both my Land Cruisers gauges are...conservative. In my 80 series if I fill up when the light comes on I get about 20 gallons in my 25.6 gallon tank. Same with the GX (17 of about 21.6 gallons.) I guess its nice to know I can push it a little, but I don’t like to.

As for the DCCD comment, just checking that you do realize there is no way to put more than 60% to the rear wheels at any given time, right? I can’t recall but I think that locked actually forces the center to 50/50, where its stock bias is 60/40 torque sensing. In theory you could get about...guessing here because I don’t know the centers TBR...80% rear under rare no front axle grip situations. I guess technically if you locked it and had the front wheels on ice then yes, the rear would get 100% torque.

I just find it annoying if I fill up at 200 miles driven and it shows 1/8 of tank if I can really make it another 100 miles before running out. Probably more if I learned to drive conservatively. My roundtrip commute is about 90 miles so I get a whole extra day of driving if I actually push it as I have discovered. But this is why I also want to drive the miata once or twice a week to work to save on fuel costs.

And yeah I dont know much if anything about DCCD other than what I have read on forums lol. All i understand is that auto is 41/59 (a change from 50/50 for the ‘04/’05) and that dialing it back puts more to the rear. But yeah it seems unclear what the limit is.

What is this winter you speak of? That is the season where it just gets dark earlier lol. But yeah I am going to take it skiing so I will get to play in the white stuff eventually! Hence my need for snow tires in the next month or so.

The forum posts about that issue is what prompted me to try the slow fill up. But considering my experiment, I dont think I actually have that issue. I have experienced having both that issue and still having it spit out the gas in another car, but that was the POS Neon lol. I think this one is actually full when it says it is.

And Thank you! I was originally looking strictly for a blob eye wrx wagon but this one was just too good of a deal to pass up. The sedans do actually look better and the hawk eyes definitely are the best. Not to mention the extra power and better transmission for an STi!

I dont even want to imagine that fuel bill lol. I am sure that would have required multiple transactions when gas was $4+ per gallon. I had a friend with a Bronco who always complained about that since the pump would force you to stop after $100

Haha I am used to 5 gallons being like almost a half a tank in my Miata. And also I am used to having no fuel light at all. It was surprising to me to see one in the Neon I had since the Civic I had before and the Miata now have none of that. Come to think of it though I dont think I have ever had a car where the fuel gauge was relatively accurate.

My gas light comes on if I have anything less than 3 gallons remaining. It’s a 17.5 gallon tank. I’m okay with this, as I know when I see the light I don’t have to panic like on other cars I’ve owned.

Yup, if I just followed the meter and didnt know about the 3 gallon thing I almost certainly would have panicked about the light coming on. Since it was nearly buried in the E at that point and 7/8ths of the gauge disappeared in around 200 miles. But now that I have learned its behavior I can probably trust the light a little more. As long as the light is not on when I leave for work, that means I should be able to make it there. Gas is a solid 15 cents cheaper there vs home so its rather important I keep track of that.

Sometimes. I would prefer a larger tank. If I’m really lucky I’ll get 310 miles on the car. Meanwhile I can get 425 miles on my Taco. Oh well, extra weight, handling, and all that jazz.

The gas gauge in my car is rather strange. I get about 220 mi to half a tank and then it takes 50 miles to get to 1/4 tank. From there it is another 20-30 miles to around 3/16 tank when the light comes on. Filling it from there takes about 10.5 gallons into a 13.2 gallon tank. My MPG gauge is also strange in that for the last 6 months I haven’t been able to get it to change from 30.5mpg. That’s accurate for my around town activities but I have calculated that I get 35mpg highway and it didn’t even budge when I did a tank of 195 miles which included running around town and 20 autocross miles. I calculated 26.2mpg and the display stubbornly continued to show 30.5.

The Mini though has nothing on my old Corolla in terms of gas gauge weirdness. The Corolla used to go 325mi on the first half of the tank. 50 miles later the light would be on and the gauge would be just above empty. There were several occasions where I would forget how quickly it drained the last half of the tank and nearly strand myself. I once managed to put 13.4 gallons into that 13.2 gallon tank.

I thought it was crazy how much gas fit in a mini when I rented one. I got 500 miles out of the 2012 I drove. I had to add oil before I ran out of gas lol. I made it all the way from San Francisco to Los Angeles on one tank!

Winter is the season for DRIFTING!!!! I live in a place that doesn’t use salt and barely uses Sand. Snow tires are key no matter what car you drive.....nothing worst then getting it sideways and realizing you don’t have enough traction to control it.

I have no idea what they do in the mountains here in Socal, it seems like they just close them when it snows. But I will find out how it is heading up to Mammoth later this month

We close the roads too in NorCal, to many people spin our and we only have so many first responders......you have to get there before they close for the most fun on the road. When the highways in and out are close locals have FUN!
