Replying to: jim314 (Jul 10, 2007 3:35 pm) The tires are actually 205/60-16 89H Hankook Optomo tires - which actually have good reviews over Tire Rack. They are 5mm larger in height (no clearance issues, btw), so I've calculated a 3% difference in actual speed vs. speed shown on speedo (i.e., speed shown on speedo is now 3% LOWER than actual speed). I've kept the tire pressure 36psi all around and the ride is a vast improvement over the stock tires - torque steer has been greatly diminished. I have no idea what the guy with the EX did for tires - the car wasn't there when I bought them As for mine? I figure I can eBay the wheel covers and then give away the tires/steel rims to a recycling center -- I don't think they have much value.

I'm thinking about a DIY rear spear install on the rear shelf of my 06 GX but want to proceed with caution. Looking at the trunk, where the CNG tank is, I believe I can fit speakers in the stock location w/o much headache. But am wondering if there was any "real" reason Honda didn't do this for any of the CNG models it has produced (98-00/01-05/06-07). Is there chance of an electrical spark from the speaker wire? If so, it seems odd because there is other electrical running near the tank... Thoughts? Anyone attempt something like this (i.e. not a surface mount solution)?

Replying to: 99civiccng (Jul 18, 2007 3:32 pm) to 2007 tank capacity -- on my 2006, i regularly get 250-260mi on a fast-fill tank. and this is in the bay area, which i would suggest means part city/ part highway due to the traffic. even after 254mi, i can only jam in 6.593GGE ... suggesting i might have eaked out a little more (though i was NOT going to try!!) i don't have personal experience with a slow fill, but as others have suggested, you can likely get even more miles. epi |

Replying to: 99civiccng (Jul 18, 2007 3:30 pm) At a true speed of 70 mph your speedo will read 68 mph and your engine rpms will be 3 % lower than with the OE tires at the same true speed. This should lower true fuel consumption per unit distance (i.e. increase true mpg) cruising on level ground at legal speeds. You have in effect raised the gearing by 3%. Unloaded diameter* of 205/60-16 is 25.69 inches. If the the OE tire was 195/65-15 (dia 24.98 in), then to get the correct values you would multiply the speedo and odo readings by 25.69/24.98 = 1.03 (1.028). *(205mm)(1in/25.4mm)(0.60)(2) + 16in = 25.685 inch If the OE tire was 195/65-15, then the dia of the new tire is larger by 0.71 inch (or 18 mm) and the radius would be larger by 9 mm. So with the new tires you get 9mm more ground clearance and the top of the vehicle is 9 mm higher above the road. This will increase your aerodynamic drag by a probably negligible amount. But if you use the same hwy cruise setting in mph reading on the speedo as you did with the OE tires, you will actually be driving 2.8% faster and so you would increase the aerodynamic part of the fuel consumption per mile by a factor of 1.028^2 = 1.057. That is, the fuel use per mile could increase by close to 5.7% because you are actually driving faster and the aerodynamic effect on fuel consumed per unit distance travelled is proportional to the speed squared. |

Why does it take so long to get one of these cars? I live in central California, and I currently have a local Honda dealer that has been looking for a 2008 Civic GX for me for over a month now--but all they can find is a white one. I will NOT accept a white or black car, as I think they are ugly. It is very frustrating to have the money to buy the car, and have the need to buy the car, have the willingness to buy the car, but NOT have the car I want available!! Am I going to have to wait 3, 4, 6 months, a year, until they find my car for me?? When I finally do get my Civic GX (assuming that time ever comes), can I use synthetic motor oil in it? |

Replying to: sierrapaul (Dec 22, 2007 3:34 pm) i of course haven't looked in a while, but i bet that you would be able to get whatever you want if you are willing to look at the LA area and SF area. my guess is that your local place just isn't willing to do to much work for you (big surprise!) another benefit potentially being a better $ deal if you are willing to do a little driving. the other thing i'm wondering ... my understanding was that only certain 'authorized' dealerships were able to sell the GX (aka - someone trained on CNG). perhaps your dealership isn't authorized, so other dealers are less willing to work with them to get you what you are looking for. i could be totally wrong, but possibly?? hopefully things work out for you soon ... we look forward to inviting you to the community. epi
