Yep, I will give it a go. Mine is close to empty.....it has two tanks, so I will fill one up and just put $50.00 in the other and see how far the $50 gets me first. I know I get two weeks on the full tanks and I do quite a bit of running around, but not sure how many kms that is. I have always thought it was quite reasonable for the car it is (Landcruiser) but I could be in for a shock!
