The main issues with E10 are it's effect on rubber fuel lines (it breaks down some rubber hoses) so it's essential to make sure the lines are ethanol safe. I personally use Millers VSPe in all my cars it protects the rubber components, stabilises the fuel so it doesn't go off as quickly and there's an octane booster in it that gives a nice little extra go. If you do a lot of miles then it can start getting expensive but this bottle is enough for 10 tank fulls - I've still changed all the hoses for R9 ethanol safe ones.
There are other additives out there, and others may have their preferences, but I'll stick with Millers for now.
Make sure you buy the hose from a reputable source as there's some dodgy fake stuff out there.
