Hey can you tell me what your settings, also I have a 98 Honda civic lx automatic, but I get only 19 mpg ...

 

^Ouch, bro. 19 mpg? Do a basic tune up. Check spark plugs and spark plug wires. Replace plugs with NGK's, use good quality spark plug wires too.

 

After changing the o2 sensor, Im getiing 32mpg

 

I just Got my 2012 HF and I'M averaging 41.8 MPH cruise control set @65 with ECON on.
only 1050 miles on it and should get better.

 

We've got a 2012 LX with similar mileage and on a recent trip at comparable speed with CC we got over 44MPG! Regardless, what's the difference between an LX and a HF. All I can determine from the brochure is that it has a spoiler. What else is there?

 

the HF is almost the same as the ex but no sunroof or HFL.
other then that they are the same.
we have a trip planed for disney land in july and i'm sure i should be around that mileage . are you using 92 or 87 octane ??

 

Using 87 octane Shell gas whenever I can find it. Do not use Walmart (Murphy) gas, it isn't top tier as recommended by Honda.

 

I use shell

 

yeh pretty much same with mine - to be honest i didn't think this was that good til i saw some other comments.

 

Yea now it's a game to stay in the Green on the freeway.
what tire psi are you running ?
I have adjusted to 40 and I think it's hurting it a little..
