I have a 2007 civic, the recommended octan is 83 regular ,
so what is the advantage and disadvantage of using higher grade octan, other than price??
Thanks

Advantage - nothing.
Disadvantage - higher cost, gas is slightly harder to ignite, so in a low compression engine with weak ignition you may actually get some misfire, lower mileage and less power.

Go with the recommended octane, if that rating is not available go a little higher but Never Lower. Higher octane is wasted money, it wont improve performance. Also, around here, the higher octane fuel is a 10% blend of ethanol which actually reduces your fuel economy slightly.

You just waste money I have a Honda and it doesn't matter if I put higher octane in it except my wallet is lighter. You should use what is called for by the manufacturer. They have the engine set up to run at that octane and if you use higher octane it only costs you more money. If your car won't run on this octane you have a problem and should go back to the dealer and have it repaired.

a waste of money. if your car doesn't require higher octane, then your not going to notice anything. i actually had a friend (i think it was a chevy), a few years back that had trouble, and she took it in several times (to the dealer), and finally 1 mechanic asked what kind of gas she put in, and it turned out the the higher octane was causing her grief (meaning the car didn't like it).
you can occasionally (maybe once or twice out of 10 times), put in a higher octane, but i wouldn't do it regularly. it might be cheaper to get a can of octane boost, and put it in every now and then. however i'd run a good/decent fuel injector cleaner every few tanks (3-5k miles).

If your car calls for 87 octane (U.S.) and you use 89 or 93 you are just wasting your money as there is really not enough benefit to warrant the extra price.

Your owner's manual specifies the fuel type to be used for good reason. Your engine control computer and associated sensors and controls are calibrated exactly to that fuel and no other. More is not always better.

there is no advantage to using premium gas in a honda that requires regular.... pound for pound there is actually less fuel value in premium the rest is additives and in you car the gas will be burned giving no advantage to your engine
