hi everyone

noob q's for the noob forum.

Context:
in australia we have the B18C2 which we all run RON98 with.
yet in USA they have the B18C1 (equivilent motor to b18c2).

In USA, the minimum Premium Unleaded RON is 91 (Regular Unleaded = 87 or so). And B18C1 owners DO pour 91octane in their B18C1.

The Question:
- Can we B18C2 owners also use RON91?
- We just wont feel the performance of RON98 right?
- Any risk of detonation n blowing the motor (stock motor)?

Cheers boys and girls
