10%... no problem. The US has used 10% for a long time now. If it goes over that, then you would need to be concerned.
This is for a vehicle that is used regularly. If a vehicle sits a lot, then you have to be concerned. Make sure you use a fuel stabilizer if the car is going to sit provided you can't find ethanol-free fuel.
What you really have to be concerned about will be small engines such as lawn mowers, etc. Boats are especially at risk with Ethanol in the fuel as moisture will cause the Ethanol and gas to separate causing all kinds of issues. If at all possible, never use Ethanol fuel in a boat.
