Thailand J Posted October 24, 2015 Share Posted October 24, 2015 A question for LPG car owners: The shop recommended changing the gas regulator every 50,000Km, is that really needed? Link to comment Share on other sites More sharing options...
canthai55 Posted October 24, 2015 Share Posted October 24, 2015 Safety issue as the rubber diaphragm can develop leaks. Link to comment Share on other sites More sharing options...
MadMac Posted October 24, 2015 Share Posted October 24, 2015 Only if it does not work properly and consumption goes up. These are very simple open loop systems. Link to comment Share on other sites More sharing options...
lj cm Posted October 24, 2015 Share Posted October 24, 2015 The following info is from http://www.go-lpg.co.uk/ . The most comprehensive site (I've seen) about LPG: LPG systems should ideally be serviced every 12 months or 12,000 miles, whichever comes sooner. As we have bulit up a picture of what can go wrong on an LPG system over long periods we have logged these occurrences and come up with preventative procedures to deal with things before they happen. Prevention is always better than cure! In general, we recommend that the following things are done at this regular interval- 1. Check security of all major items, LPG pipes, tank(s), fillers, Etc. 2. Check performance and emissions using an Exhaust Gas Analyser 3. Check the whole LPG system for leaks using leak detection equipment 4. Drain any 'Heavy Ends' from the vaporiser 5. Check LPG filters and replace if required (additional cost of the filters applies) 6. Make recommendations for any remedial work required Link to comment Share on other sites More sharing options...
lj cm Posted October 26, 2015 Share Posted October 26, 2015 Maybe it is a good idea to change the gas regulator/vaporizer every 40-50,000 km. I've driven 90,000 km on LPG and are now changing it for the second time. It's not broken, but it leak's water. It has (like) white powder around the rubber seal from evaporating water. The shop says; it cannot be repaired, but has to be changed. That's OK; and then we don't have to think about 'Heavy Ends'. PS! They also recommend to change the LPG Filter every 40,000 km.

VocalNeal Posted October 27, 2015 Share Posted October 27, 2015 (edited) If it still starts, runs, performs OK, fuel usage is OK. Then leave it. As soon as it starts to run rough or use more fuel or.. Then get the LPG system serviced. What they do depends on whether you take it to a place that sells LPG systems or a place that sells and services LPG systems. If you see a few taxis in for service , that place is probably OK? HINT: As TV no longer shows contributor's location, maybe start the question with. I live in Nakon Nowhere and... Then if people have businesses they trust in near your location...?
