My car is e10 compatible but I prefer not to use it, however I will run a tank through when I am going on a long trip. The fuel can suck up any moisture in your system and pass it through injectors with no problem. I also believe that it does clean an engine though happy to be corrected.
Firstly a lot of 2 stroke oils are not compatible with alcohol/ethanol fuels, read the labels before buying oil.
E10 is crap i don't use it unless there is nothing else.
The energy content in SI units will be Mega joules per KG,ethanol and methanol have lower energy levels so you have to use more of it to provide the same heat energy.
The E10 waters your fuel down with a lower energy substitute, you will increase fuel consumption using a lower energy fuel.
E85 is another story, the car needs to be setup for it with bigger injectors,fuel pumps etc and it can usually be tuned with more ignition advance and is safer for engines tuned to the limit.
You will burn a lot more of it as the energy in MJ per Kg is much lower than petrol yet it will make more power in turbos, high compression big cammed engines etc.
Diesel has a higher energy content compared to petrol,of course the higher compression ratios in diesels improve efficiency, this is why diesels get better economy.
