My sister bought me 2 dedicated ford 250 trucks. sadly there is no cng station in west Texas. So I filled one in Dallas at a clean energy station that measures in gge and was very sloooow, about 2700 psi was all I could get. I towed the other one 240 miles round trip to midland, to fill. That pump, which sits out in the middle of no where, measures in gallons. I barely had time to put my credit card back in my wallet be fore that pump had shoved 2.9 gallons at a full 3000 psi into the tanks. My question is how do you convert gallons into gge and do all 3 tanks fill at the same time or do you have to have the ignition on? cost was $4.25 a gallon

Re: gallon conversion
GGE and gallons (as far as a CNG dispenser is concerned) are the same thing. CNG sold at a public station is sold as a gasoline gallon equivalent (GGE). This means you are getting the same "equivalent" amount of energy as you would if you bought a gallon of gasoline. This is about 123 cubic feet of natural gas. Unless you have manual valves on your tanks, all tanks should fill regardless of the ignition switch position. You really should have the ignition switch off when fueling. Ignition could possibly mean many things if you fill with it on
. It seems like the Clean Energy station you were using was having a problem if it provided low pressure and a slow fill. It is possible the storage was low and either the compressor was inoperative or was running to fill the storage when you arrived. $4.25 a gallon seems very high in price

Re: gallon conversion
Sounds like you need a pump to fill at your home or business location. There are slow fill pumps called vehicle refueling appliances available to do just that.Last edited by Curtis; 06-23-2009, 11:17 PM.Comment

Re: gallon conversion
On the fuel station website for Midland it shows $1.05 per gge. At the pump itself it says $4.25 per gallon, underneath that it says 1 gge= 5.67 pounds. The trucks hold 13 gges total, so I'm assuming I got full tanks.Comment

Re: gallon conversion
West texas does'nt use much NG, its all propane. I sure was looking forward to using the lift gates on the trucks. I'm just going to play with them for a bit , then take them back to dallas and get rid of them.Comment

Re: gallon conversion
I checked the fuel price history of the midland cng station, $4.25 was from june of 2008. I noticed that ng prices followed oil prices exactly, talk about price gouging, where was the congress investigation? It looks like the NG companies use all of the same excuses.Comment
