Hi,

I just bought a 2008 honda civic hybrid less than a month ago, which has about 106000 miles on it. I'm getting about 24-26 MPG in the city, but seemed to give me better MPG on the highway. I am not sure if the previous owner did any tuneups.

I'd appreciate any suggestion on how to increase the MPG and what are the tuneups I should get done in order to increase the fuel economy? I do not drive aggressive.

Also, is K&N air filters are better or should just use paper OEM air filter to be on the safe side?

How many spark pkugs does it need? is it 8?

Thank you very much for any information..

 

I guess nobody wants to help here......

 

I recently bought a 2011 Honda Civic Hybrid with 116,xxx miles on it. I think it was the same model that you have (had? Seeing that the last post was in 2013). I’m getting about the same amount of miles on it as you did. I replaced the belt. I’ll be replacing the 8 sparkies and cleaning the MAF & throttle body. Hopefully I’ll get some promising results.

 

I just want to note that there's probably like 3 honda civics in the world that take 8 spark plugs..... 99% of them take 4 plugs and like a very small percentage will take 3 plugs. There's a couple of V6 swaps out there, but again - not applicable. You most likely have 4 plugs... all of yall.
