Fuel tank capacity?

My Toyota RAV4 manual says the fuel tank holds 15.9 US gallons. I ran the RAV4 deep into the red the other day, yet it only took 12.7 gallons. Question, how far past empty has anyone ran their RAV4?

I poured 15 gallons yesterday, that is my record.

Dean, Is someone dumping a little sumped avgas in at work while you're out buzzing around?

The RAV4 has a 60 liter tank--doesn't matter if it's made in Japan or Canada, or sold in N. America, Europe, or the Far East. I've checked the spec sheets and even the diesel RAV4's have a 60 liter (15.9 gallon) tank. From what I've read, 60 liters is a standard size for small Japanese cars. The reason is if they went with a larger tank, the manufacturer is taxed as if it's a larger car. For example, my daughter's Altima also has a 60 liter tank, while my mother's larger Maxima has a 70 liter tank.

Wildly inaccurate fuel gauge. Makes the small tank seem even smaller. Used to always refill at about 1/4 tank. On my Rav4 if I do that I only put in about 9 gal. Running it 10-20 miles after the fuel light comes on lets me put in about 12.7-12.9 gal. To put in 15 gal I would have to drive about 75 miles after the fuel light comes on.

Like RF, my gauge seems to be very accurate. The other day the needle was at EXACTLY 1/2 and I filled it up. Took just a little under 8 gallons. And when the low fuel light comes on I have about 4 gallons left.

I don't think I've ever reached 13 gallons at fill up, but I almost always wait for the light.
Good to know I've got plenty of buffer, plus it's generally a good not to run the tank dry anyway.

According to this website (Tank on Empty: Toyota RAV4 ), the average distance to empty, after the light, on the RAV4 is about 33 miles.
That can't be right...I've run it close to 33 miles after the light, and even at 13 gallons to fill up, there's still almost 3 gallons left in the tank.
It looks like that's just what people have said they've driven after the light turns on...and then filled up; not how far they've gotten after the light turns on to run the tank dry.

Aside: Mentioned earlier, but I cannot find the net-source - in Australia they offered an auxiliary gas tank that fed the stock tank. Australia is vast and if you want to drive into the interior you NEED lots of fuel.

I would be very grateful if anyone can find that source again.

Just filled yesterday right on a quarter, got 10.7 gallons IIRC.

A gas gauge is not a super precise measurement, nor does it need to be. And I suspect gas pump calibrations also vary more than they are supposed to, which would impact alleged fill quantity.

Just bought our 2010 in January. I topped off the 3/4 tank the dealer gave me at the first station. Drove home from Ohio, then had to go back with Wifey to pick my car back up. Then the next day, Wifey ran around and I had to take it and fill it up. Pulling into the station the light came on and the needle was less than 1/8 tank. I put 12.5 gallons in it.

My wife used 1/4 tank going to work (or anywhere for that matter, we live near nothing.) I filled it up for her every 3 days work. I'm finding the Rav4 is the same, she uses 1/4 tank going to work. The big difference is, it would take $49 to fill up the old Tribute at the now high price and it takes less than $40 to fill up the RAV4. Helps a little since I fill my tank once a week just under half a tank and fill hers twice a week at 1/4 tank.

That's better than what I had witnessed.

I saw a girl post that her car gets worse gas mileage as the price goes up. She was calculating miles driven by $ amount paid for the gas, LOL.

342 miles / $48 put in the tank, 7.1 mpg. Not very good gas mileage, LOL.

If you want to get really accurate, try to use the exact same pump if possible as each pump, even at the same station, can have different cut-offs. Drive until at least half the tank is used (the more the better) to have a more accurate reading.

If you want to really find out just carry a couple gallons in one of those new totally sealed gas "cans" and run it out.

I actually used to calibrate the gas gauges on all my cars, engineer style. I'd run them out in my garage by disconnecting the return fuel line and draw a diagram of the needle positions as I added a gallon at a time.

This discussion reminds me of the Seinfeld when Kramer and the car salesman see just how long they can go after hitting E on the gauge...
