HEY! My last fill up (and it was a big one at 104L) got me an average of 18.4L/100km. Which is right on par with what the truck's indicated mileage showed for the tank. (I recently discovered that I could customize the various display screens with instantaneous mileage, trip mileage, tank mileage, and overall mileage...so I put all 4 in there). That tank was mostly city, with a little bit of highway. So, not bad. It's also what the truck is rated for in the city.
MILEAGE IS GETTING BETTER

Another interesting little nugget of information: I brought that tank down all the way to 1/8 of a tank. So, pretty empty, right? Wrong. My truck has a 144L fuel tank, and at 1/8th of a tank, it took 104L to fill, meaning there was still an additional 40L in the tank. I could have done an additional 217kms city, which is a crazy amount of reserve range. The reserve on my Tundra is equivalent to the fuel tank size on some small cars.
