Reply #71: it depends, diesel used to be 90 cents a liter

[comtec]

now its' 1.32/L, petrol has gone from 1.10/l to 1.60.
so its' all relative.
a gallon is a bit under 4 L, a royal gallon (UK) is 4 L.
Hybrids (prius) re selling like mad, and I imagine as soon as a diesel hybrid hits the market, there'll be a 3 year wait list immediately LOL.
