You'll have the least chances of knocking... even if you do start knocking, the knock sensor would kick in and retard the timing... I guess it'll run more efficient.
hmm... come to think of it, I should have used higher octane or at least some octane booster in my car before I dynoed...

I've been thinking about this more and more... seems like a not so bad idea for me to start using something better than regular - due to the advanced timing in the flash. Probably only cost $3 more on average per fill up.
C&D did a test a while back as well... Ram and Mustang actually gained some hp, while the V6 Accord lost a few % in power/performance.

YMMV... but you probably wouldn't notice the difference. You're fine which ever one you use. In most cases, I would assume the engine will run more efficiently.

Running higher octane then needed does not make your car go faster. It really is just a waste of money.
Turbos Prefer Premium
Did some regular vs. premium tests after I drove my 2013 Sonata turbo off the lot. Got about 10% better MPG with premium.
Similar experience in my previous car, SAAB 9-5 wagon with turbo.
When my budget was tighter, rule of thumb was to add 10% to regular gas price and compare to premium. If premium was less than 110% of regular, more cost-effective to go with premium.
Turbo and wastegate provide variable compression. If the fuel octane is higher, turbo boost can be higher, effectively raising compression ratio. This can provide more power or higher efficiency - your choice. Non-turbo/compressor engines don't have as much adjustment range, thus are unlikely to get as much benefit from premium.
Tend to cruise between 80 & 85 mph. Get 31 - 34 MPG with premium fuel, Econ mode and a light foot. Light traffic and staying on cruise control gets a few more MPG. Also have the trunk lid spoiler for some aero benefit.
Do not measure your MPG after changing fuel grade or brand until you're at least halfway through the tank. The ECU needs time to learn how much boost pressure and timing adjustment is possible before engine knock starts.

We also found a better mpg with our Accent using premium gas.

You actually get better fuel economy with 93 octane fuel.
I have also found that even though I run 93 octane, if I want really good fuel economy I should run a fuel injector cleaner through every 5th or 6th tank. It makes a massive difference. I would think those of you who have been running regular (87 octane) fuel could benefit even more from a bottle. Sold in most gas stations for 4 -5 bucks, just make sure you get the one that is for gasoline cars and not diesel engines.
