Does anyone now if I will gain any power on an 07 civic ex if I use 93 octane gas instead of 87?

 

No, you won't get any benefit at all. All octaine does is increase the fuels resistance to detonate. The higher the octane the less likely it is to detonate early which causes 'knocking'. That's why it is used in higher compression / performance engines.

NOPE!!!!!!!!!

And octane boosters from Walmart or any other place won't increase power either.

 

that pretty much raps it up.

 

Not to mention it won't completely combust properly. Higher octane meant for high compression.

Not neccessarily. Higher octane fuel has a higher flash point. Due to this the higher octane fuel is more likely to burn completely than a lower octane. Due to engine technology and better fuel formulation it's a bit of a moot point though. Bottom line is to use the octane specified in your manual. Using higher octane won't do anything but cost you more money.
