Just a few days ago my '02 went 55 miles with the fuel light on. I wasn't driving it at the time, a dealership employee was. It didn't even actually run out of gas, that's just how far it was to the next station. He said 55 miles with the light on was exactly what he could get with his '98, too. I assume he was driving at highway speed since he was on a highway, but I don't know how fast exactly.

The most so far that I had driven with the light on with my '00 was 58 miles, and it took 6.5 gge at 4400 psi!...so if dejapooh put that much in at 3600, then no matter what Honda says, the newer models MUST have a larger tank. I still think mine is only a 7. My additional one in the backseat then is an 8 (one can see it is bigger than the original) because now it could hold 13 gge at 4400. I've also noticed since the tune-up that I could go over 60 miles now with the light on.

#31 of 38 Adding additional tanks to the GX by ngvdrivers

I bought a 2007 GX last month and want to see what the cost would be to add an additional 3600 psi tank NEW and of the same quality as the factory tank. Do Honda dealers offer this service or do you have to find an aftermarket tank? If anyone knows the cost to add another tank of the same size as the factory one, please include details.
 
If you add the 2nd tank to the trunk, does it take up all of the remaining space? If so, I guess I'll need to remove the spare from the trunk.

Not sure about who best to have add another tank or the cost, but you for darned sure better have it in writing in your American Honda warranty that adding a tank will NOT impact the factory warranty on the car and/or fuel system!
Maybe add it after you hit the 3yr/36K miles...?
 
Let us know what you find out - I hope to order an '08 GX when they come out and may want to think about adding a tank also. (That's after I put in 2 rear speakers!)

I went out on my first longer range trip this weekend. I was going from Thousand oaks to Beaumont (just west of Palm Springs). I started off with about half a tank and made it to Burbank (WOO HOO, Love that $1.774 price, and it REALLY fills). Burbank filled me to full for the first time (no lighted dots were left unlit). I Popped off the hose (and it seemed to almost explode off the tank), and reset my trip meter. Got out to Beaumont and made a few side trips. By the time I left for home, I was at 180 miles on the trip and just under Half a tank showing. I figured I needed to hit some gas, so I stopped in San Bernadino... Nothing there! On to the next station, I forget, which, Closed to the public (you need an Account to fill). the Covena Station is closed on sunday, so I barely made it into Azusa. 258.7 miles from my last fill (Yellow light on, Fuel lights off). That's by far the best range I've gotten on a tank. What's your highest range on a tank.

nice! i love the feeling of gas light on, no bars left! liberating!!
 
i consistently get over 250 on a tank in SF bay area driving ... with several in the 265 mi range. i currently average 40 mpg consistently, and usually squeeze in 6.0 - 6.5 GGE when i fill at 3600.

Hi adea, I just joined this site and found your post from July 07 regarding the addition of an extra CNG tank in your Civc in Mesa, AZ for only $800! I live in Southern California, but would be willing to drive to Mesa to have an extra tank installed at this price. Could you reply with the contact info for the shop? Thanks, Adrian

Hi adrianr. My family and I are traveling to arizona this weekend. Would you share who did the job for you with your extra tank. We might need to replace ours and this seems like a great option.
 
Thanks

Hi danaman...this is adea...I just talked to the guy a few weeks ago that installs these and did mine a few years ago. He had to temporarily move to Queen Creek. The name of his company is Alt Fuel Systems and his name is Mark. His number is: 480-363-3436. He told me that he may not have any more 'steel' tanks (you can ask him when you call him), but he can install a tank the original size and composition (kevlar/carbon) for somewhere between $1300-1500 which still is a great deal! Good luck!
