6.0 = --0026
1_6.2 = --0005

I then filled the tank to the brim and then got

6.0 = --0057
1_6.2 = --0057

This corresponds with the 57 litres I put in the tank, but given that the tank on the ZT is 65 litres, does this mean mine is misreading by 8 litres? It would certainly explain why I seem to get less than 300 miles on a full tank. I knew with my other car it was about 320 miles to E.
These results fit with what I found today: test 6.0 and 6.2 seem to give similar readings (within a few litres), although yours are a lot closer than mine.
