I've always done this for my cars\trucks, every oil and filter change, tires and other assorted parts. Since I never trade in my vehicles and keep them at least ten or more years, the list can get long. (I give the vehicle away when I want to upgrade.) On appliances for the home, I always keep the owners manuals and make notes in them as needed. (Sadly, some newer appliances don't have paper manuals any longer.) The only flaw in my system is I tend to use a kind of short-hand in my record keeping. Thus, when I gave my Mazda 5 minivan to my daughter and son-in-law, I had to explained a few things. :-) A word of caution: Never give away a vehicle that isn't in safe working operation! I put a lot of money in the above Mazda to keep it safe for myself. I would still be driving it, I just needed a truck.
