2nd LP regulator fail in 2 years - oil in regulator!!?

All,

thanks for the very good inputs. That's definitely something to think about. This sounds like it should be a very well known problem then, so it's surprising that the LP regulator isn't made with a sediment trap or similar built-in.

If the problem is only when high pressure vapor is allowed to sit, perhaps it would be good practice to get the vapor out before winter storage? I could simply close the main shut off valve and use the stove until the lines are empty.
