I do this all the time with oil filters. When ordering parts for something that you need now, it make sense to buy some oil filters to amortize the shipping cost. I currently have 4 oil filters for the '83TD and 3 for the '87. I like stocking up on the consumable parts like oil filters and light bulbs.
