Using higher fuel octane
My 2014 T-X manual says use only premium grade fuel rated at 95 octane. Here in the middle east we have 93 95 97 octane with 97 being "premium" grade. What affects are there using higher octane greater than what the manual prescribes? Are there any harmful affects using a higher octane?Thanks

Generally no. It just hurts your bank account and doesn't add any benefit if your engine can't take advantage of it.
SC engines love higher octane. It reduces the risk of knock and allows the timing to be advanced, improving performance etc.
I would also say be careful on octane ratings, the US/Canada have different rating than say countries in Europe. I'm sure someone will chirp in with the comparable grades, but for us in Sweden, we have 95 (normal), 97/98 (Super) and that's it. In Germany they even have 100!
So chances are your manual will be referencing US/CAN grades.

Thank you. I'll have to do some research on middle east fuel octane to determine octane comparisons

always use the highest available octane pump fuel for a boosted motor
too much will not hurt a thing too little will
