I will start my reply saying I don’t understand much about cars.

My answer to you, OP, is that various mechanics recommended me I use at least 95 and try to avoid anything lower. Why, I’m not exactly sure but they said it’s better for the engine and that it will help my fuel sensor, which is a bit faulty, not light up prematurely or erroneously. I sure feel the difference on the motorway, lots of hills here.
