Might need to double check your calcs there mate. Find it very difficult to believe you are getting those kind of figures.

I'm currently getting less than 7.5lt per 100km in my 2013 Y61 Patrol, Diesel, Manual.

I'd suggest there is something wrong with your maths/calculator there. In any case once the bullbar, snorkel roof rack are fitted watch the fuel consumption going AWOL.

I reckon you have figured to kms per litre = 7.5km/lt

so the math is 7.5/100 = 13.33lts per 100kms

hey mate , thats works out at about 13lt per 100klms, pretty sure main an sub hold 130 litres all up

The main tank is 95lt standard and the sub tank is 30lt from factory.

The sub tank does not supply the fuel pump but rather is transferred to the main tank via an inline pump that completely empties the tank.

Really your best bet to get an average it to monitor over the next few full tanks what your usage is on average.

I Always, Always run both tanks to empty and wait for my fuel light to come on. I alway press my odometer when i fill up and i alway take note of exactly the odometer when the fuel light comes on from the main tank before i press transfer of the sub then again when the light comes on for both tanks empty.

I then fill both tanks to full and first check how much i pump into the sub tank to check the calibration of the pump (about 32lt on average) and then look at how much overall. You tend to get a good feel for how your car is driving and will see whenever there is a fluctuation.

For those that are not sure how to work out the maths.

take your Odometer reading, devide by the litres pumped will give you the number of kms you traveled per litre pumped. Then devide 100 by that number.

ie.
1000kms driven and 120lt pumped

1000 / 120 = 8.33
8.33kms per lt
100 / 8.33 = 12lt/100

Hope that helps some.

I'm getting 900km + off a tank (90lt+30=120lt) 900/120=7.5

Hope I'm not wrong? And that's city driving, no freeways

That works out to be 13.3L/100kms

If you're happy and you know it tap a post!

That's what I was saying! You just cut in with your post before I had a chance to finish off the maths.
As I was saying 100/7.5=.......,

Lol

Some people hey...

[Wtf_mate_lol]

I was using about 13L/100k on my ZD30 before roo chip and exhaust and intercooler upgrade mostly 115km/h

ok guys thanks for that , will do again an thanks

About to pick our Patrol up tomorrow, fingers crossed. Going to be very interested in checking fuel consumption. What is the general consensus or protocol with the subtank, do most keep it as reserve for a while or do you always try to transfer to the main before filling and top both up at the bowser?
