It's more likely that something else is going on.

I've run 93 in my car since I bought it(~5,000 miles of driving), and haven't noticed any problems. In my area, 87,89, and 93 are the common choices.

Buy a code reader or take the car to a parts store(Autozone, O'Reillys, Advance Auto, etc...) and have the codes pulled.

I have this code reader: https://www.amazon.com/BAFX-Products...d2+code+reader

It will likely pay for itself several times over, especially if you have multiple vehicles with OBD2.

I used regular 87 octane on the 171796 miles on my previous 06 G35 6 speed manual until I traded it in for my present 2012 G37S that now has 75k miles.
It has never seen a drop of premium.
Round trips from NJ to Florida produce these results
Short trips while in Florida show up clearly with much lower MPG

Recently got 27.83 MPG between NJ and Ashland, Va. a distance of 316 miles and it took 11.356.gallons to fill-up on regular 87 octane.

93. I guess 91 might be okay also. Sounds like you have other issues going on. Using regular will just make the car feel a little sluggish, not cause check engine lights

Chevron 91 octane premium, which is the best we can get here in SoCal!

I tried using mid grade for a couple fill ups and it just didn't work out, 20% lower fuel economy driving around the city that just wasn't worth it.

It doesn't matter what grade of gas you put in your car. Short trips, frequent starts and stops result in poor MPG

The only accurate test is highway driving for 300+ miles with no or minimal stops

Im going to bring it in to the dealer and get a oil chang and they will cheek it and see what is wrong.
