We had much the same when our fuel went from being sold in gallons to being sold in litres. In gallons a penny or two difference in price is not worth getting bothered about but given that there's four and a half litres in a UK gallon, a penny or two is quite considerable, you can spend, or save, depending how savvy you are, as much as ten pounds on a tank full of fuel.In actuality most of the original tariff increase will be absorbed & kept as a permanent increase here in the US. But it may appear that we are getting something. We will actually be paying more & getting less since the 700ml bottle was legalized at the end of Dec 2020. We will soon be paying a little less, but getting 700ml instead of 750ml.
Makes me feel better. " Look what we did." It's all in the spin.
