Replying to: epnfrn (Feb 21, 2008 5:01 pm) Does anyone know how often these need to be changed? I just had my 60k service, and they said it didn't need to be changed. I am thinking it is because they weren't certified to service the GX. I had it changed at 30k miles, and recall that it was expensive...Also, side note, I just had to have the transmission replaced.

Replying to: winky1 (Feb 22, 2008 11:10 am) the owner's manual recommends low filter change every 10k, high pressure every 30k. lots of discussion around here on how important those numbers are when your Methane supply is clean. b

The factory recommendation assumes you have a wet and oily gas supply as happens with oil-filled compressors, cold temperatures and/or private gas wells. If your gas is clean and dry like my utility supplies in Southern California and you're using an oilless compressor at home, you don't need to change them nearly that often. I changed mine at 100k on one GX. They came out awfully clean. I plan to change the filters on the other one at 100k although I probably don't need to.
