Absolutely this.
We paid $119 for 38L of diesel last week. I don't remember the exact cost of the fuel but I wanna say around $2.80.
A full tank usually costs us around $75.
I got half a tank of 91 a few weeks back at 224/L and it cost me $60. That's what a full tank would usually cost me...
Nothing really. We don't buy many premium things from the shops, we don't buy expensive clothes and we don't live outside our means.
Wouldn't really know where we could save money to be honest.
