Re: Civic VX -post your MPG

^My experience seems similar to yours. What brand 02 sensor did you get?

I'm assuming you're addressing me. I looked up the info this morning:

NTK NGK 24300 Oxygen Sensor

ordered from OxygenSensor.Net

Re: Civic VX -post your MPG

Thanks. I've considered getting the 24300 before.

I have been trying to get my idling issues fixed, and I also have a headgasket job in the future.

However, I just used a tank treatment of Red Line SI-1 and the idle/acceleration has improved along with the adjustments relative to the low idle issue.

Next to fix the coolant leak! Still getting only 40 MPG or so with my relatively short commutes (majority of trips are 5 miles or less).

Re: Civic VX -post your MPG

Since not all gas stations will top off your tank the same. One half a gallon when you are only filling up six gallons of a ten gallon tank, makes a big difference on what your fuel economy appears to be. So I got 47 miles to the gallon with my last fill up. Also I just installed a new muffler the old one had a blow out. I am hoping the little extra back pressure may help the O2 sensor work properly for a little more mpg's.

For instance, what model tires do you have specifically? Thanks!

Is the 02 sensor the original?
My tires are Michelin LRRs at 44 psi. The O2 sensor was replaced when the car was restored two years ago. Sorry, but I hadn't read this thread in a long time and I just saw your question!!! I can give you the model number of the tires if you'd like. Hope that helps!

This car was restored by a forum member on here, Chris, who goes by the name "Honda Guy" ... He can give you all kinds of details of the work he did to get my VX back on the road. He did a fantastic job.

That's insane! But I am dubious that the fill up was to the same point in the tank as what it was at at the beginning of the tank. Did you employ any hypermiling techniques? How many gallons was the tank?

My last tank I drove 654 miles. Kinda hard to believe! Filled up 10.4 gallons for just under 63mpg. Over 80% highway driving. Lotta hills, though. 60% of the tank had some kind of cargo such as a desk I was hauling around in the back and a passenger I took to the airport with two bags.

Last tank went a whopping 688.5 miles on less than 10 gallons of gas for a 1/2 mpg shy of 70mpg.

I'm getting anywhere from 37 to 44mpg on my 94 VX. On the 93 I can't tell, the speedo and odometer doesn't work at the moment.
