I have a '98 4.5 with an 80L lpg tank an a 50L petrol and I get 250kms around town and about 300 on the highway.

I don't even run the thing on petrol as my trips in it are to the South Coast (200kms each way and heaps of LPG availability) and when I go out to the tracks it is usually about 150km round trip. The range is fine for my purposes.

Wasn't prepared to fork out for a 4.2TD for my first 4x4 but wanted a bit of grunt for towing my boat so the 4.5 on gas was the only real choice.

In saying that when I get a newer Patrol, it will be a TD for sure.
