First, all fuel is the same. It is branded from the refinery for each brand. One is not better than the other.
I attached the requirements below for you for the fuel octane. It is recommended 87 or higher. It will not damage the converter at all. The higher the octane, the better the performance.
I would not use any additives either. The fuel has all the additives that is needed.
FUEL TYPE: UNLEADED gasoline
OCTANE RATING: 87 or higher (Research Octane Number 91)
For improved vehicle performance, the use of premium unleaded gasoline with an Octane Rating of 91 (Research Octane Number 96) or higher is recommended.
FUEL TANK CAPACITY:. 79 L (21 gal, 17.5 Imp. Gal.)
