It very much depends on what kind of car you drive. Any car built after 2017/2018 has been designed to run on E10 and so there should be no affects from using it, other than a potentially small reduction in fuel economy.

If you run an older car you may want to consider using an additive, as it can help prevent damage to your engine and fuel system caused by the ethanol. Ethanol can cause corrosion and other issues in engines and fuel systems, so using a protectant can help prolong the life of your vehicle.
