I have truma GOk gas regulator, of recent haven’t been able to get any gas through to any of the appliances in the caravan, thought it was the bottle, so exchanged it and got another bottle, still no joy , so removed the regulator and found it had oil in it , surely this isn’t right , would this affect the connecting pipes also ?
Gas regulator

Its a very well known issue, these reportedly are prone to this effect where exposed to "oils" migrating from the gas bottle.
Other designs, again reportedly can better tolerate it.
One can argue the gas should be "clean", but evidence here with certain regulators, and also known with fridge jets, is it is not necessarily clean.
Things are it seems aggravated where the regulator is not positioned above the bottle, though it still has occurred.
There is a gas oil trap available to help mitigate the issue.
Edit: it was discussed back here LINK

As previous said , I have removed the GOK style regulator, I have ordered a truma mono regulator which is a bit more modern, I have room to mount it higher in the front locker as I want to replace the cooper pipe from its junction with tee lower in the locker in case of any contamination, I’m hoping this solves the issue
I have read the link , and as in many publications on this topic, all the articles go back a good few years, hopefully truma and calor have sorted the problem by now
The problem is ongoing - high-mounted regulator with no dips in the flexible pipework is the only fix although an oil filter may help..
The problem is that high pressure LPG leaches oil & chemicals out of the flexible pipework - this will drain back into the cylinder if the regulator is higher than the cylinder and then be purged when the cylinder goes back for refilling - otherwise the oil & chemicals collect in the regulator and eventually block it.
