You can use E10.
Any EFI car can tolerate ethanol based fuels up to 20%.
Hence why the fuel is limited to 10% Ethanol.
The tradeoff is higher fuel consumption, the engine management system strives for correct Air/fuel ratios, the engine then uses more on average.
If the fuel is 10% cheaper, but consumption is 15 % higher, then non-based ethanol fuels are still cheaper overall.
I have never used E10 myself, since my own testing has proved for many years that premium based fuels (98 octane) achieve lower cents per km.
I hope my advice has been of assistance to you.
