How much do u get out of a full tank?

[GtiRboy]

I regularly get over 650km to a tank every week.

100k's on the freeway everyday at 100km/h.

Just the other week i reached 700km, but i reckon i only had like 4-5 litres left in the tank(had to go searching for 98!!!!!).

And i do hit it quite a bit, practically lift about 2 times a day.

This is all on Caltex Vortex 98

When i first brought my car and drove it back from sunshine coast, i got about 720km's out of the first tank, and it didn't even hit the warning light yet... mind you though, i was driving a little under the speed limit, was double demerits that weekend, but don't think qld had them rules, but i still didn't want a speeding fine in my new car registered in someone else's name...

but i just filled up today, was a little under half tank still, and i had 310km's, and that's with hitting lift more than a few times ...
