The previous owner of my TD would cut out a piece of the box that the oil filter came in and right down the "due next" date and miles on it and just use regular scotch tape.
I maintain a maintenance log. I went out and bought a standard blue canvas 3 ring binder and some lined paper. I made columns with headings across the top of each page. Date, Miles, Work Performed, Where (home, dealer etc) and Cost. Since oil changes are the most frequent and most important, I darken in the "O" in Oil change to make it stand out.
I got the idea to do this from E-bay. One day I was looking a Ferraris and one of the owners documented everything and kept it in a 3 ring binder. Each page was in one of those plastic page protectors. It's an excellent way to keep track of work receipts and invoices for parts.
It may seem real anal, but have no doubt, I know exactly every what, when, where and why and how much, with my cars. An added benefit is if in the event I were to sell a car, well document maintenance is worth $$$$. Would anybody here pay good money for an undocument vehicle?
