I use airplane logbooks, Airframe for the chassis, and Powerplant for the engine. I document mods, parts replaced and non repetitive service. Wheel bearings, trans oil, gasket replacement ect. is recorded with date, mileage and part number. Don't care about the cost.

I'm terrible at keeping track of these sort of things, so I bought 2 of these, 1 for the 911 and 1 for the daily driver. I keep track of major service items and I store receipts for part purchases in a box of maintenance records the previous owner (24 years owned) kept.

Excel spread sheet with work description, date started, date completed, mileage, source of parts and cost.
Never, ever total the cost column!!!!!!

Started out with a list, then several lists which evolved into an unorganized mess. I then put all of this info into a book (or magazine) form using Adobe ID. I add a few pages from time to time and include projects, events, costs and future plans. It will be fun to go back and read as I get older and the memory slips away......

I'm in the small note-book club mostly. Write down the fuel fills, oil changes, any normal maintenance things in that. Maybe once a year or so I transfer the actual maintenance items (usually this is tax time) to a spread-sheet I have. That has what all the PO's did to the car that I got when purchased.
Mostly did this as part of my engine rebuild project many years back now to log the part numbers purchased and that cost. Also more recently the complete suspension re-fresh.

I keep a small Marimekko notebook with a log of all the maintenance and other work I've done (mileage and date), parts purchased (date, cost), a running list of projects, and so on. I save fuel receipts and tell myself I will put them in a table or spreadsheet but in reality I just end up with a Ziploc baggy(ies) full of receipts.

I keep all the receipts of all products installed on the car, but not oils and such. I do however keep a running list of all servicing with dates and service done, but not cost.

I created a Google Docs spreadsheet for my car, and typed in all the maintenance history I got from POs. Then I continued adding my own history to that. Date, miles, work done, who did it, cost, warranty on parts, and other notes. Those are the columns I have. I had never done this for a car before, but it has been massively helpful. When I'm wondering, "When was the last time the MTF fluid was changed," I can check. From anywhere, because it's in the cloud! (Always make sure you say "cloud" with a Scottish accent.)

Someone beat me to it...+1 for the Google Docs. Really easy to access at anytime. Mine is also backed up on my external hard-drive at home.

Yep, Google Docs is cool. I use Dropbox and have a dedicated laptop that just sits in the garage.

Here's the Excel sheet I use to keep track of stuff:

Anyone have any fancy Excel maintenance logs they use or created?

As a rule I don't let anyone work on my car and I stay on top of all my vehicles.
Things that have a lifespan get marked when they are installed. For example I print the mileage on a labeler and put it on the oil filter. (For my other vehicles with the oil filter on the bottom, I also put the mileage on the filler cap.) Fuel filter has the mileage written in Sharpie. Large hoses get labeled.
For things that are variable I inspect them regularly. Brake pad thickness can be seen every time I check the air pressure. The brakes are used hard so the brake system is flushed after every track day and Targa Baja. Small hoses and belts are under the heading "inspection items" too.

As far as documenting what activities the car has is pretty easy because I have lots of pictures and they are all stored on my network with the various folder names starting with the date. [year]-[month]-[day] [description] For example: "\2017-10-06 Road Atlanta"

Yes to a log book. It's just a hand written informal affair that records the nature of the work and the mileage. Receipts are kept as well but in my last move, I lost a bunch. No worries, I plan on keeping the car forever. I find the log book helpful when I can't remember when (or if) something was done. Maybe I should graduate to some of the fine spreadsheet examples others have posted - impressive! I too do all my own work, sadly, it seems whenever I pay someone to do something, there is a problem.

I use an app called AUTOsist. It lets me create my own service records which are then searchable by key word and date. I can take pictures of receipts and create a fully annotated service record in PDF. It’s actually pretty slick. You get one car for free and multiple for a couple bucks. There’s also a fleet version with maintenance alarms for you big collectors. Downside is the app on my mobile device is laggy.

Are you new to using spreadsheets?
You are adding a column for every type of repair.
Instead, you should have a column called "Repair Description"
and each repair gets a new row.

I keep a little book in the glove box with all work I have done on my cars and when at what miles and which parts were changed out .... tires oils filters plugs wires brakes etc. ...more or less. For some reason on the Miata I even started recording the gas gallons of gas miles on fill-ups to get an idea of gas milage. My dad did this on all his cars, an engineer habit i guess and I probably do it because it gets great gas mileadge. Don't know if I will keep the car, but will know where it is as far as mechanics go..

I have a running spreadsheet of all service performed and parts purchased. It has served me well in the past when selling a vehicle. I dont plan on ever selling mine but I still keep the record keeping going.

I use a few concurrent methods:

- Each vehicle has a notebook and everything is logged by hand (all maintenance, every fill-up, notable dates/times/locations/mileage events, etc).

- I maintain a Google Docs spreadsheet with routine maintenance items (oil change, tire rotations, etc). I track last time something was done and when it's due next. I have some conditional formatting which highlights items needing/approaching service. I check this about nce a month to plan maintenance due each month.

- I keep a file of receipts for each vehicle (maintenance/major improvements/fixes only) and just throw items in the file as they get done. (The 911 file is ~3" thick right now...)

I've got a small Marimekko notebook that I used to record maintenance with date and mileage, parts purchased with date and cost, my running to-do list, etc. I do keep all my gas receipts and I tell myself I will put it all in a spreadsheet but I never do. I probably have all 25 years worth of gas receipts for my Sentra SE-R but have I ever put it in a spreadsheet? No.

The columns are fixed maintenance descriptors, I don't add any new ones. The rows below get an 'x' each time I do the maintenance. I just add the date/mileage on the row like a regular logbook but add the same date/mileage to the current column. This way it gives me a running total of the last time it was performed in years/miles. The colors in the yr/mi box gradually change from green to red as the current date or miles pass the due date/miles I specified.

i Keep every receipt. Any parts taken off the car are kept as spares since I replace wear items before they fail. And I have an odd love affair with factory hardware. Every nut and bolt taken off is labeled and stored. Always nice to have one as a reference if I have to pick up something in a pinch.
