the fuel may have only been just released but it was released with the intention on being compatible with all unleaded cars. i wouldnt be running a really high percentage of ethanol but as its only 10% im sort of struggling to see how it could do damage..
Ethanol has less energy per mol compared to petrol, hence why it produces less power. For each mole theres only 1/2 the power.

Ethanol has a higher ignition temperature

Ethanol is highly miscible in water and such can easily be contaminated. The fact that this is seen as a 'lower' grade fuel makes this worse.

Ethanol doesn't provide the same lubrication as petrol as its surface tension and viscosity are completely different

It can do damage by increasing the temperature at the heads due to its higher ignition temp.

Also u look at cars that have fuel/gas...there bad cars that are setup on only fuel or just gas run fine if there tuned to suit that.

If you had a car that was adequatly tuned to ethanol mixture, you would find it would run fine. But most cars are tuned to premium fuel so the facyt that theres ethanol in there, in a sense its an impurity (it dsnt fire as well as what petrol does)
