Effectively, I use E95 where available. When not available, I used to make a 50/50 mix during the first part of the journey adding E95-10 to the E95 remaining in half the tank approximately. The rest of the journey, I would use E98 if I could not find the E95 at all. I also read that the E95-10 is not recommended to our cars and therefore avoid having a full tank of it
