In theory you are correct but I know of several modern cars that are suffering worse fuel consumption since the change, the wifes 2016 Mini for example used to do an average of 36mpg according the cars readout, since the change it now does 33mpg. The car is freshly serviced and runs perfectly. Out of interest I filled it with E5 97 Octane instead of E5 and it jumped back up to 36 over that tankfull.


Trying to convince the wife to spend more on fuel is now the problem. Luckily she only does 4 to 5 k a year so it is not going to bankrupt us but if this is true over Millions of cars how much extra is the UK using annualy?

Quote----The car is freshly serviced and runs perfectly.

A difference in mpg sounds reasonable but others posts are quoting different problems like poor starting.---

That's why I suggested other problems rather than the fuel not igniting correctly or not at all.
