You are in the Honda Civic GX (natural gas)

#1 of 24 Regular service

I have a 2007 Civic GX and I am just over 5000 miles. They recommend 7500 before oil changes, but my neighbor said I should stick to 5000 miles. I was thinking that at 5000 miles, I can also get the filter work done when it needed to be done when needed. Also, the 15,000 mile oil change involved more than just oil and such. When I bought my car, they gave me 4 major oil changes (the 15000 mile kind). Also, what kind of oil should I have them use? Synthetic or natural? Weight?
Finally, Do you have to buy the new filters from Honda, or is there another place to get them for less? I've seen recommendations on here that said the filters do not need to be changed, except to keep the guarantee valid... are there any final thoughts on that?

dejapooh .... if you have not already done so, go read your owner's manual! the owner's manual was written by the same engineers that built the car. not the salespeople, not the advertisers, ... the people who know the car best - the engineers. unless your neighbor was one of these folks, i would pass on their advice. the GX is a special car (as you know) and thus has different schedules. therefore the old 3k/5k/7.5k debate doesn't apply. this type of information can be found directly in the manual.
in fact, i don't think 5000mi or 7500mi is suggested, but rather ~10k (rather they say that your car's cpu will tell you, and estimate 10k'ish). i don't have it in front of me, so forgive me if i'm wrong on that. b/c this car uses CNG, which of course is much much cleaner, the oil actually maintains it's integrity much longer. one of the regulars here has quoted a honda study that showed excellent oil integrity after 50k.
we're glad to have you among the enlightened CNG few! if you have more questions after reading the manual, let me know!

Not sure if Honda automible filters are the same as motorcycle filters, but back in the day we always bought Honda filters for our bikes because of a 1 way valve in the filter. Without getting technical once the engine is turned off the valve closes to keep the oil in the heads and prevent seapage back into the pan. If this is still true then I would recommend the Honda filter.

On oil changes the cost per mile is very small for 5k or 7.5 k . At $ 35 for a dealer oil change , at 5 k thats $0.007 per mile , at 7.5 k thats 0.0047 per mile. The real large cost is cng fuel filter changes. try about $0.025
per mile. thats about $ 250.00 per 10,000 miles driven. Check your GX Owner supplement and call the dealer for cng fuel filter prices. Be sure you are sitting in the car with seat belt fastened when you make the call ! Some posters on this board have stated that changing the gas filters is not needed. I have never seen HONDA specify service too often. Example , coolant 120,000 miles , spark plugs 105,000 miles.
At list prices, honda cng components are not cheap. Fuel injectors are close to $800.00 each and the high pressure regulator assy is about $2800.00 , plus labor !. so if you want to risk voiding the warranty by skipping fuel filter changes, go ahead. If you are using the Phill , no chance of an oil contamination. 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).Just my 2 cents worth from 2 car / 5 year of cng vehicle ownership

GX injectors should retail for $500-$600 even my dealer cost on them is $397. Was curious if anyone has tried to replace the CNG filter themselves and what the dealer wanted for the part? And if theres an aftermarket replacement for it like a NAPA filter. The CNG filter is right above the oil filter and appears to spin on and looks similar to the oil filter only it's red. For those of you who haven't dont it a may want to try BEWARE it's under pressure. I've seen the filter but haven't taken it off yet or gotten the #'s off the filter.

Hi Murphy. The spin on is the low pressure filter on the 01 and later. List is about $125 . You can get them for about $87 by mail order. I have cut one open and it is like an oil filter with a thicker shell. At 10,000 miles it was very clean inside. The high pressure filter is more like a strainer. It list's for about $45. My dealer charges about .5 labor for the low pressure and about 1.0 hrs for the high pressure. The last time I had the spin on changed, the part # on the box was 16230-PMS-A03. It also has an alternate #. The filter says mfg by Toyo Roki Mfg. trngf-6A18

Murphy...I just changed my fuel filter (only one) on my '00 GX. The filter from Honda costs about $36 and from AutoZone $27 including tax. I bought the Honda one this time (salesperson recommended me to) until I can compare the two. Previous to installing it, I bought the supplemental manual from Helminc. I bought the car with 75K miles on it and I don't think the fuel filter was ever changed, but it didn't look that bad actually considering it probably had 118K on it.

On the 2006 and newer Civic GX, the low pressure CNG fuel filter is much more expensive, $253.80 at Majestic Honda which is 30% off retail price. I'm not sure why a fuel filter cost so much, but changing it every 10-15k miles will eat up a lot of the maintenance savings typically afforded by natural gas combustion. FYI- part number 16905-RNE-A00.
Does anyone know what the cost of the high pressure CNG filter is on the 2006 GX, or what the part number is? Hopefully it is not outrageous!

I have a 2000 and only one fuel filter...high pressure. It costs $25 at AutoZone and $32 at Honda.
