Hey, thanks for making this video. I've had my 318 for 4 years and never changed the oil. Today I finally did (after watching your video), and the oil was dark black. I need to learn how to take care of this great tractor, and I'm looking forward to watching all your 318 videos. I have a plow, 2-stage snowblower (the refrigerator), a front scoop, and a mower deck for it. I use it a lot, and need to keep it in good shape.
