What to write down after each visit so the log is still useful next year.
A maintenance log is a list of work done to one car. It is not a diary and it is not a catalog of parts. If a stranger could tell what was done, when, and at which kilometers, the row is good enough.
You can keep this on paper. If you would rather have it on your phone, the RPMBase car maintenance tracker keeps the same habit: one car, one row per visit, with room for the next due date.
01
Name the car once
Make, model, year, and today's odometer. Everything else hangs off that car. If you own two, start two logs. Do not mix them.
02
Write the job in plain language
Oil and filter, front pads, battery, inspection, or a general service. Use the words you would say out loud. Add the shop's name only if you want it later.
03
Add the three numbers
Date, odometer, and cost. If you only have two, save two. A blank kilometer field is better than a number you invented in the parking lot.
04
Copy the next due mark
If the invoice or the sticker gives a date or a kilometer target, put it on the same row. That is what a reminder can use later.
05
File the paper
Keep the invoice photo or the PDF with the row. The log should still make sense if you never open the photo again.
What belongs in the log
Services and repairs belong here: oil, filters, brakes, tires, battery, coolant, belts, inspections, and diagnostic visits that ended in real work.
Fuel does not belong in the maintenance log. Neither does the yearly insurance bill. Those are real costs, and they have their own places, so the service list stays readable.
What you can skip
You do not need the part number, the technician's name, or a photo of the waiting room. You do not need to rate the shop. If a line on the invoice was only a recommendation and the work was not done, do not log it as done.
Skip rows you cannot source. A log with honest gaps is more trustworthy than a log that looks complete and is not.
How far back should a car maintenance log go?ShowHide
As far as your invoices go. Start with the latest oil change or service if that is all you have. Add older rows when you find the paper. Honest gaps beat a fake complete car maintenance schedule.
What if the shop did several jobs on one visit?ShowHide
One visit can be one row that names each job (oil change, cabin filter, inspection), with one date, one odometer reading, and one total. Split it only if you need separate due dates on your maintenance schedule.
Does fuel belong in the car maintenance log?ShowHide
No. Fill-ups go in the fuel tracker. Insurance and tax go in expenses. The maintenance log stays the work: oil change, brakes, filters, tires, repairs.
How is a digital car maintenance log different from a paper book?ShowHide
The stamped book still matters. A digital log is searchable: last oil change, kilometers, cost, next due. RPMBase is that copy on your phone, not a replacement for the official stamp.
