I keep records on all work I do on my cars. It's easy since there is usually a receipt involved every time. I just write on the receipt when the particular item was installed. I also keep all my fuel receipts as it is becomes an MPG log. I guess I can also keep track of my yearly fuel expenses that way as well.
