2011 civic gas type


#1

I have a 2011 civic that recommends 87 octane or higher. Is it bad to put 91 octane in all the time?? Would it damage anything?


#2

Just your wallet. For your engine, there is no benefit or danger.


#3

You can spend your money on anything you want, but premium gas won’t help your car at all.


#4

You are just throwing your money away. Start buying 87 octane and save your money.


#5

Higher octane does not damage the car. The fuel is slightly cleaner and better for the car in hot weather. In moderate or cold weather there is very little benefit.


#6

Interesting screen name . . . considering you’re asking a question about a Honda Civic

I’d save my money and use the 87. If you tow or haul heavy items in a pickup, the manual suggests using a higher octane. Neither of those is your situation, unless your mother in law is 900 pounds or over
