Silly question Re: sub-tank

Hi Guys.

My Prado GXL (Diesel) is only a month or so old. Great car to drive.

The literature stated that it had 2 tanks totalling 150 litres. When I open the fuel cap there is only 1 nozzle to put the fuel in.

Am I right in assuming that the car puts the petrol in the 2 tanks and manages the usage??

Also - the fuel range shows a low klm (approx. 100 to go) but when I fill up it only takes about 130 litres (meaning that there was still 20 litres in the tank). Maybe the range is being conservative??

That's normal. There's plenty of posts on the subject. Do a quick search.

Consider the 2 tanks as one with a skinny pipe section between the 2 - they are in series.
the range is rather conservative.

Thanks for the prompt replies.

Makes sense

Stick your head underneath you will see the pipe splitting into a Y to fill both tanks
got mine down to 10km and got 138L, trip computer will calibrate itself over time.
Depending how much foam is generated when filling can have an impact as well

I can actually hear when I start filling the smaller of the 2 tanks. With about 65 litres to go, the noise changes as the tank that closer to the filler starts filling up.

Diesel in a petrol engine doesn't work too well either!.:lol:

Fule Tank Capacity

Hi,
Did you find a good explanation for your question?
I have the same question, as I have run my tanks down until the gauge says there is just 5klms to go.
But, it only takes 134 litres to completely refill.
I have done this very slowly again, making sure there were no air locks or excessive foaming when showing about 50 klms to empty.
That time it took 130 litres.

So, is there about 20 litres to spare after it shows 0 klms to go?

thanks,

There's 22L left according to the manual.
