@Matt Bollinger posted:What oil should I use for my O gauge trains? Im looking for oil I can get cheap at stores like Walmart. I don't care what brand, just the type. I read that WD40 can seize the wheels & gears of locomotives, so I don't want to get a random type & have it be the wrong oil.
Matt... the "which oil," & the "Can I use lamp oil as smoke fluid?" question are asked here about twice a month. Do a search here for lubricants, or oil for trains, and you will find many threads.
