95 is E10, 98 is E5. E 10 is alright but thhe Ethanol may damage seals in some older engines, none of our engines are affected. The only thing is the higher ethanol content gives less efficiency leading to slightly higher fuel consumpttion but it would proably not be noticeable.
I seem to remember reading the performance and efficiency losses could be as much as 10%
Most articles say you will use more fuel and end up paying more.
As land used to grow crops for ethanol isnt being used for food, possibly increasing food prices, it tends to be pretty intensive too.
Add into the mix the energy, and pollution to produce the ethanol. Really does make you wonder if its worth it.
Also many manufacturers wont give straight answers whether older cars will be able to use it without problems - ask em to put it in writing
For the extra cost and performance increase I wouldnt risk it
