Hyundai GS: Distance per Tank

Hi folks,

Got this idea after my Baguio trip. Please bear with me. Also, though it may be or eventually be related to the fuel consumption thread, my intention is just to catalog the distance portion.

So, without further ado, please put down the farthest you've travelled on a single tankful of gas.

Please also include:
- the date around when this achieved
- year/variant of your GS
- composition of the drive (i.e. mainly hiway, mainly city, mixed)
