Excellent videos. I have worked with natural gas and propane for my entire career and my oil knowledge was somewhat limited. I have been using these videos as a self training course to increase my skill set and abilities. Thank you very much for your work and all of this information.
only just found your channel and videos, but they have so much information its great, could really do with a pdf though to print out some slides as a reminder.
