Does remapping actually save you fuel?

I found good gains from BP diesel over UK Fuels. Its only over two weeks so far but I’m seeing .7 mpg better on similar work. That’s on the trip and on “first click to first click”.

That’s interesting, I had a BP card and didn’t use it as it was un competitive against UK fuels for price. After much hassle about non use age of the card, ran solely on BP for a month and found fuel consumption was worse (Work did not alter).

That’s why I’m running the trial over at least a month. Early signs are promising but I need more data to be sure. I’ll run on BP or Shell (eurogarages take UK Fuels cards and don’t have separate bunkerage for UK/Key Fuels) until the end of March and compare against January.
