When did you stop recording at fill-ups?

I'm at 4500 miles and plan on continuing to track until I trade it in, probably sometime after I've put on 100-150k miles.

 

I stopped the last time I filled up. But I'll probably start up again on the next fill up

lost all data after about 3 months and said screw it...


but that's just me

 

Never got into that, though I'm as rabid as anyone at calculating each tank.

 

72,000 miles and still counting - using a database on my PDA makes it easy!

 

I keep a book with milage and fillups, and also record oil changes and other maintenance stuff done. I will use it to prove to toyota that the maintenance (oil changes, tire rotation, filters) was done in case I have a warranty issue.

 

I wish I would have been calculating MPG for the past 15 years. The Prius has really opened up my eyes to fuel efficiency and conservative driving techniques.

I plan on recording MPG data for the rest of my lifetime.

 

[all mpg in this post is based on UK gallons]

Indeed, I have done since my first car in 1974, and yes, it IS an eye opener (using note books until pocket computers became available)

My second car, and first automatic, was a 1968 1.3 litre - (European) auto boxes were horribly inefficient in those days, and it only got just over 23 mpg overall - occasionally did 36 on a run.

Modern (GM) 1.8 and 2 litre autos in the 1990s managed mid 30s and I was happy with that. A Volvo automatic 1.8 only gave about 25 mpg overall, and it was slow accelerating at low speed and noisy on the motorway (freeway). I then switch to a small car, a 1.3 Toyota Yaris auto, which managed about 42, so I've been delighted the last 3½ years to get 51 out of the 2 Classic Prius I've owned. The Prius also beats the Volvo and Yaris hands down on acceleration at any speed up to it's limited 99 mph.

 

I made this Excel file to keep track of everything that is done on the Prius. It drives my wife nuts but all she has to do is write the ODO on the fuel receipt. She's the one that drives it mostly, she's all over our county with her job. Before the Prius she was spending over $300 a month on gas, now it's down to $135 or so.

There's my spread sheet that I keep track of everything on.

Let my know what you think.

 

Same here. The freeware TotalCar app makes data entry a snap, and I can track multiple cars for fuel and maintenance. It has a module to record collision data, too, but I'm not going to use that feature.

 

Same here! I have a bound notebook, I record everything in, including my mpg experiments and customizations on the car. And I have done that since my first car. I thought everybody did that.

As for the mpg I transfer data to my spreadsheet so no more hand calculating. If you don't watch for trends, how would you know if your car was heading toward a problem? By the time you get an error code it could be a bit late! But most anything going wrong with engine or HV battery would show up first in a mpg drop.

I record any unusual computer glitches too, in case they are the start of a trend.
Like the other day I had abs and other brake warnings. I rebooted and all was fine, but it went into my notebook.

I may drop posting in green hybrid eventually but plan to do it for two years, so any break-in trend should show up there.

 

Same here, did that with every car I've owned, as long as I've owned it.

 

Always have. Always will.

Every one should always record mileage for any car. It is a good way to track engine performance. When mpg drops unexpectedly, it can be a sign of impending trouble. With hybrids a sudden drop may be due to weather or tire pressure or a change in driving style, but only a history of mpg data can help you know.

 

2001 Prius, 79427 statute miles, 1770.8 US gallons, USD$3182.97

Claims of 46 mpg exclude the driving done with roofrack, etc.

 

Same here -- I use DocumentsToGo, and record it on a spreadsheet that I can view in Excel on the Mac.

Yes, I'm an engineer. Why do you ask?

 

Weinernectk - Thanks for the spreadsheet and the suggestion about spouses. I'll be the one that wants to track it and my husband will be the primary user. I'll use both your suggestion on the gas slip and the spreadsheet!

As to original question - never did for any other car. On 2nd tank of Prius and plan to track!

 

I tracked it throughout the time I had my '03. For the FEH, I've even added to the spreadsheet to include the price per gallon to fill the tank, how much I paid, and since I'm carpooling, how much both myself, and the co-worker have paid. I'm also tracking the cost to fuel the vehicle overall.

 

20468 miles, 394.674 gallons, I do it so when someone driving a SUV says I get 26 mpg I pull out my palm and show them the data and ask for theirs. Mostly they don't keep track they are quoting the best number they saw on the sticker when they bought the car. The price of gas is not nearly high enough to change people habits.
