I am no math expert, but this has me stumped.

Had the car one week, this Friday. Toyota gave "free" 500 baht gas. I put in 1000 baht (2 x 500). Last one being this past Wednesday when the yellow light came on. I do not drive much, city driving.

Car has 187 km, gas bought 3 times 1500 baht / 38 baht per litre= 39.4 litres/187= 4.84 km per ltr.

My toyota prerunner did better than that.

This is a 1.5cc engine, as opposed to my very much missed 3.0 cc diesel.

Yesterday I put in 28 ltr of fuel, reset the trip odo to 0 and will study this again.

My point is, is this normal?

These numbers arent normal.

Why not go back to the dealer and ask their opinion about it?

Are you sure Toyota put in 500bt free fuel, that's about 1/3 of a tank?

Was that showing on the fuel gauge when you picked the car up?

The only real way to get a reasonably accurate figure is full tank to full tank. So fill it up ... do the mileage and then fill it up again. The petrol flap tank does lock I assume?

Even with just 1,00THB of fuel, around 6km/l really is excessive fuel consumption. While fuel consumption is a bit higher on a new car for a while, there's something really wrong with that figure. Take it back to Toyota. If there's nothing wrong, hide the spare key.

The tank was almost half a tank when I drove out of the dealer lot. I like the full tank to full tank idea. Will do it if my readings later this week also show low gas mileage. The petrol flap does lock.

Lock up the Key.

I have a 2013 (new shape) manual gear Vios. I don't very often fill it up, normally just 500 baht of E20. That gives me constantly about 220 km, which if you do the maths;

500 baht (E20) at 36 baht a litre = 13.8 litres

220 km on 13.8 litres = about 15 km per litre.

My driving is a bit of a mix, city and highway.
