With Nissan recommending premium gas for the Infiniti does anyone run with 89 octane?
I would not entertain 87 but was wondering about 89 ?
I ran my Maxima with 89 mostly with 91 or 94 every 6-7 fills and things seemed fine.

I have been running 87 in my 2011 G25 for quite some time. (Dozens of tank fulls) I don't notice any difference. Apparently the only thing is a 10% loss in HP. I don't race my car, and I don't need to be going 200kms/hr, so I don't mind if I'm bumped down to 200HP.

The new technology in cars can adapt to any fuel. I just won't get the top performance out of my car while using 87. I've done over 1000kms on one tank of all highway driving. All done with regular 87 octane fuel. I almost seem to get better fuel economy with 87.

That's my real world experience for you.
