2007 Honda Civic GX: 20 Minutes and Still Not Full!

June 11, 2009

Just a quick FYI for you Civic GX owners -- if at all possible, fuel up at the natural gas pumps that are rated at 3600 psi. Use the 3000 psi pumps and, as my colleague Mr. Clark suggested, you best not be in a hurry. I recently filled the GX twice in succession -- once at a 3600 psi pump (near LAX airport) and once at a 3000 psi pump (located near our office in Santa Monica).

In each instance, the GX's tank was down to about a quarter (five bars showing on the gauge). It took less than five minutes to fill it (19 bars -- though it reads to 20, that's the most we've ever seen) at the 3600 psi pump, where, after nearly 20 minutes at the 3000 psi pump, it still wasn't full.

Both times, the pumps quickly filled up the tank to 80 percent or so (the fuel pump shows the percentage of fill) but where the higher pressure pump topped off the tank in short order, the lower pressure one took forever and still didn't fill it. Which brings up another FYI -- even though the pump shows "100 percent", the tank isn't really full until the "100" stops blinking. That sucker blinked for a quarter of an hour (while the pump gauge's "Gallon's Equivalent" numbers moved ever so slowly) before I had to abort the mission and get back to the office, the end result being 17 bars showing.
