"At the public stations I once got a real big slug of oil in the CNG. (the station had a bad compressor and it was sending out a lot of oil with the fuel)."
Question: How could you tell? I mean, did you actually see the oil somehow? Or did the station tech just tell you the compressor was bad?
And more generally, for anyone who might know... People have mentioned particular filling stations as being better or worse about how much compressor oil is in the gas... Again, how can you tell? Is it just that your fuel filter is dirtier after regular use of one station as opposed to another, or can you tell right away? I'll have a choice of a couple of stations on my regular route to work, and I'd obviously like to avoid "dirty" gas if possible. (I'm in CA, bay area, if that makes any difference.)

Kate...I just had a repair bill over $600 on my 2000 GX with 120k miles because of 'dirty' fuel. The worst for oil is Trillium and next is CE. Never had ANY problems before I started using CE and Trillium. Now, I travel 30 miles just to get 'clean' fuel. (extra filtering so oil doesn't get in the fuel) I've been using CNG since '98 and when I used Trillium for one year in my Toyota Celica, the cng side didn't pass emissions! (gasoline passed with very low numbers)...I found out that all that oil going in with the fuel produced too many hydrocarbons and it didn't pass. Now, I was forced to use it again (less than 3 miles away), and this time major repairs! (injector, ignition control module, distributor cap, rotor, ignition coil, spark plugs, wires, and O2 sensor. I've also talked to drivers who told me that CE & Trillium caused problems for their vehicle too. So ask the station owners if they have extra filtering to keep the oil out and other contaminants...then ask other drivers that use that fuel to verify that they have had no problems.

It was with my 2000 cng crown vic , not my gx. the nozzle was a little oily , but the next clue was over 16 gge showing on the dispenser on a car with 10 gge total capacity. The station went down for major maint. (compressor shortly after that day) . Then my plugs fouled and a catalytic converter went bad . I do not recall if ford uses a filter or just a strainer.

Thanks for the tips, Garry. Who's clean, in your opinion? My only convenient options are going to be the Trillium station in Berkeley (which sounds like it should be my last choice) and a bunch of PG&E stations north of there. Looks like I could go a bit out of my way and get Pinnacle.
Anyone in the PG&E service area with an opinion on their gas?

kate - i use the berkeley trillium on a regular basis. i have never had a problem, and i always worry about one person's problem at one station becoming a blanket statement of 'never go to trillium or CE or whatever'. clearly, if there is a castrophic problem, there is nothing you can do ... but if there is indeed some amount of oil coming through (and i personally don't have any reason to believe there is) then that is what those two filters are for!
my neighbor works for PG&E and drives a CNG Camry. i brought this issue up with him once, and he reacted as if it is no longer a real concern. who knows for sure? it might be worth calling the Berkeley garbage folks down the street ... they have been filling up there for a long time, and their chief mechanic probably knows best what issues (if any) they've had.
the one thing i really don't like about the trillium in berkeley is that ridiculous diesel engine that is used to pump up the pressure ... every time it fires up i think to myself 'yeah, CNG is better for the environment' ... too bad that ridiculous engine probably takes it back 2 steps for the 1 we're going forward.
#18 of 24 98 civic gx - routine maintenance
Oct 27, 2009 (11:32 am)
im the proud new owner of a 98 civic GX(124k miles), which i picked up over the weekend. the car was purchased by the previous owner from a fleet auction in sac so no maintenance records were provided to me at the time of sale.
i tried to pull up more info on the specifics on the motor that are special for cng but couldnt find details online nor any helpful info from the user's manual, which basically is just a normal civic manual.
question i have: in terms of maintenance what should i be looking at or better question is where can i find a maintenance schedule for these cars?
ive read conflicting info about the fuel low and high filter replacement schedule. what is correct? low done at 10k mile and high at 30k?
also as far as the oil filter, is this a normal civic filter or is there one specific for a gx? how difficult is it to change out the fuel filters? ive done routine maintenance on normal gas engines like changing out fuel pumps and filters but cng is a totally new world for me. i am mechanically inclined but definitely not a mechanic
any other helpful info in terms of what i should look for on a car with this mileage will be helpful. i plan to do some of the normal tune-up items that are routine for a car w/ this mileage.
does anyone know if its typical for gov agencies or pg&e to be on top of the maintenance for these cars? if so, is there anyway to pull-up records from honda if in fact the work was done there? it woudl be nice to not have to change out a timing belt if its not needed.
#20 of 24 Changing Civic GX Fuel Filter
Jan 17, 2009 (10:14 pm)
I'm at 10k miles right now and I've been reading that the high pressure fuel filter needs to be changed. Does anyone have the part # for this part?
Also, does anyone know where or how to change this filter? I'm pretty knowledgeable about cars so I can probably change it myself, but I just don't know the location of the filter.
thanks in advanced for your help

I have 40,000 (just turned it tonight). I have yet to change my fuel filters. From what I understand, The engine will begin to fail when they need to be replaced (water is the primary thing filtered). There will be no damage to the engine if you run until the filters are dirty. Because this is a gas fuel and not a liquid fuel, the filters work differently...
Am I right here guys?

Where and how many fuel filters depends on the year.
As far as the engine failing if you don't change the filters, that's correct, it will fail. If your fuel source has water and/or oil in it you can foul one or more of injectors which are expensive to diagnose and replace.
I have a home compressor and utility gas, so I have virtually no chance of having oil or water in my gas. But, if you fill at commercial stations you are at greater risk. Or if your source is a home well you are at the greatest risk of problems from fuel contamination.
