Has using E10 caused my fuel economy to drop?
I have a 2019 Honda CRV 1.5 AWD with 11,000 miles, full service history and not due a service until May 2022. I had been averaging around 34/33 mpg until recently. My fuel economy has dropped to 28/26 mpg. My route hasn't changed I believe I have been using the new petrol E10. Is this mpg drop to be expected with the recent formula change to petrol?
If this is the case I would be using approximately half a gallon more petrol for every twenty pound spent at the pump. I don't see how this could be any benefit to the environment burning more fuel only an advantage to Government taxes and the fuel companies.

I'm not convinced this has anything to do with the switch to E10 fuel.
This generation of Honda CR-V was launched in 2018, which means it has been developed (and WLTP) tested with E10 fuel. And even if E10 did increase fuel consumption, I would not expect it to result in a dramatic 20 per cent cut in mpg.
It could simply be caused by the cold weather (fuel economy can drop by 15-25 per cent in the winter) or it may be an issue with the fuel or air filter.
Alternatively, there may be a fault with one of the spark plugs or oxygen sensors.
When did you last check your tyre pressures? A slow puncture of low PSI rating will inevitably increase rolling resistance and result in more fuel use.

Real MPG enables you to register the fuel economy you are actually getting against your make and model of car, its engine and type of transmission.
Every time you enter an average consumption figure against your car, the overall average automatically adjusts to reflect it.
