The instructions for my Masterbuilt 30" smoker do not mention using any kind of oil on the grates or inner surfaces to season it before the first use. The book simply tells me to turn the thing on for a few hours and then let it cool. My question is, is there any reason to apply oil anyway? As in, does the food taste better, is the smoker easier to clean as a result, etc.? Or, if the book does not mention oil, should I NOT apply any for seasoning? Thanks for answering the newb questions! I'm sure I'll have more!
