E10 petrol - will it damage my modern classics?

I’m concerned about the introduction of E10 (petrol) and the impact it will have on my 1997 Jeep Cherokee and 1988 Porsche 944 Lux Auto. Is there anything I should be contemplating having done to them (and what would be the approximate costs) or should I sell them both immediately?

I've been running cars in Thailand on E20 (20% bio) for 6 or 7 years with no ill effects. Cheapest way to get the higher octane fuel. But if you think you might need additives, consult

You should not anyway have been running either of these cars on 95 Ron. The both need 97-99Ron Super to perform properly.
