Another glow plug question

I know that there is a huge thread on this but I searched about 12 of the 36 or so pages and got sick of looking and seeing the same problem discussed over and over and not finding the info that I need. My problem is not that my glow plugs are not working, but today after I changed my oil back to summer wieght (15-40 from 10-30) I was driving along and I noticed that my glow plug light was on in my instrament cluster and it wasn't turning off. What is this about? Is this my gpr acting up? I turned the ignition switch off and started it again and the problem went away but who knows if it is going to start again. I am going on a 1700 kilometre trip in 4 days and I don't need this happening on the road in the middle of nowhere. Some advice on this would be greatly appreaciated.
Thanks

I would try a power cycle of the batteries which involves disconnecting BOTH battery ground terminals and waiting 5 minutes. Turn on lights too as this will discharge any stored charge in capacitors. Reconnect and see how things go.
