Anything over 750km per tank is bs. I have been driving fleet cars since 2002 in the wheatbelt of WA. I have driven VX's, VY's and VZ's and I own a VX and have never got more than about 750 out of a tank (all country driving). Plus we always have 5 cars on hand and there changed over every 6 months or so (because we rake up 100 thou by then), so I have probably had 20-30 cars to compare.
