When you have the memory of a guppy and you work on small engines, you do not want to fire up an engine whose oil you've drained and forgotten to refill. Believe me. So... to avoid that potential issue, I have created these key chain tags that I snap onto the key rings of vehicles as soon as I drain the oil and remove once I have refilled them as a reminder.
Book / loose leaf rings, like these from Amazon, make snapping them on and off key rings a snap, no pun intended.... but I'll go with it :)
