I have worked up a simple maintaince program using Excel. While doing it I realized that a lot of it personal preference such as I change my oil every 3000 miles because my car sees severe duty. I only drive about 1.5 miles to work and 1.5 miles home. Sometimes the car may be driven more and sometimes I may drive it 1000 miles over a long weekend.
SO here is my version. If someone would want different items or miles or time let me know and I will make the modifications and send it to you.
The spreadsheet is easy to use, just inter the current mileage in the first line (in the block).
Now enter the dates (such as 12\9\04) and mileage for each of the services. You can get these dates and mileages from your records of your last service for that item and then just change the date and mileage when the service is done the next time. Now any time you want to check to see if a service is due, enter the current mileage at the top of the page and it will show how many days or miles until the service is due again. Items that are preformed by mileage are shown as how many miles until it is due again. Items done by time (such as Change Brake Fluid every 2 Years) are shown as how many days until due again.
Let me know what you think.

Here it is
