Minimum is RON95, but RON97 is the lowest grade EURO4M fuel. No need to use RON100.
My previous car Civic FD2 Concept M came with Ecotint. I feel my previous car Honda City installed with VKool Elite and my wife's HR-V installed with Llumar has better heat rejection.

In any case, just to share with LYN forumers, I tried the remote start from my office in level 4. Blocked by a few thick walls and windows. My car started without a hitch came in the car a few minutes later all cooled down already. Funny thing was a few of my colleagues was gathered around admiring the car, and they were surprised when it suddenly started on it's own. When I told them I remote started it from my workplace, they were all very impressed I must have been a good 25 meters away from the car - do try it out!
