So do you record any information when filling up?

Well short of going in and buying the stuff while the gas is pumping and then coming back out and placing the nozzle back and going in again to pay for gas how would you do it?

Can't simply move your car right away before you pay for the gas in case someone resets the total.

Miles/Gallons purchased.

Always fill up your tank and it becomes ridiculously easy to calculate gas mileage.

I do know some people do this to test the different fuel efficiency of certain types of gasoline.

High octane=worse gas mileage

Well more along the line of the type of gas stations.

I never really noticed a difference with the stations around me. They were all pretty much the same. In the winter my mileage would go down. It was that scam oxygenation chemical they put into the mix. I don't think they do it anymore after they found it was contaminating ground water :^/

High octane gas burns cooler, so you don't get as much power out of a gallon of fuel. That's why you shouldn't use it unless your car specifically needs it(turbo, high compression...)

Edit:
grammar

They don't use MTBE or ETBE anymore, but all gasoline is still oxygenated in the form of ethanol.

The reason for worse fuel economy in the winter is two fold; first, "winter blend" gasoline contains physically less energy than summer blend. Second, it takes your car longer to warm up during the colder months, meaning the fuel system spends more time feeding your engine a rich mixture, reducing fuel economy.

Ah, that's it. I couldn't remember what it was for the life of me. I need to go to bed. I'm just sitting here poking keys like a monkey :^D

 

[Muse]

You bet. The miles on my odo. When I get home I take the receipt and make an entry into my gas table in my custom information data system, including the odo reading, gallons, price/gallon. The application automatically calculates my miles/gallon, all the info is right there to browse for the history on both my cars.

 

[dawp]

I usually just set the trip meter when I fill up. pretty good way to notice any changes in milage.



My dad does this and it's just to monitor fuel usage. But he just record milage and gallons pumped.

 

[GeekDrew]

Yeah, every time I fill up... odometer reading, station brand, octane, cost per gallon, quantity, total price. I enter it into Vehicle Manager for Windows Mobile. I have no reason to... I'm just anal retentive that way. I also keep track of maintenance and etc using the same program. I also reset the trip meter every time I fill up.

And what's this about getting lower mileage with higher octane fuels? I've always experienced the exact opposite... is it because of the way my vehicles have been designed to operate or 'tuned'?

 

[chin311]

i used "ROAD TRIP LITE" for the iPhone, keeps track of MPG, gas price & gallons filled etc.

usually i remember to do it, helps keep track, i think my "AVG" is about 29mpg

If your vehicle's engine doesn't require high octane fuel, (high compression engine, turbo-charged, etc.) then your engine won't burn high octane fuel correctly and you may even get lower gas mileage. .

[thomsbrain]

I just use my Scangauge.

I have found that most gas pumps sucks a fair bit of gas back into the vapor recovery system or something. There's like half a gallon or so of "extra" gas that always gets pumped regardless of how much of the tank you used. So I've taken to avoiding fillups until I've used most of the tank. If I drive 30 miles and get 30 miles to the gallon but pump 1.4 gallons, I know the pump is fucking me in the ass. I have my Scangauge set to compensate for this over a tank of gas, but for small fillups, it doesn't have enough time to balance out the seemingly constant overfill.

My sister and I are also required to do this (as we're technically driving their cars), and they're quite anal about it. Granted on such a small issue I don't mind complying, but when I asked them why we do it they gave me a vague response about visa bills with no real detail. Given that I almost always pay in cash or with my debit card, that makes no sense when applied to me and my sister.

Anyone else able to shed some light on this? Just curious if there's an actual reason or if it's yet another of my parents' OCD habits.

Heh my parents do this too. When I first started driving, I had to as well since it was their car and such. Now the habit rubbed off and I find myself recording everything too! I don't know why, I just do.

 

[HardcoreRobot]

reset the trip meter

 

[Possessed Freak]

Yes, I recorded my MPG all the time... until my odometer stopped working.

 

[Sasiki]

It really helps when selling a car if you can show any time the car was touched.. gas fill ups, oil, tire pressure checked, etc. It shows that you took good care of the car.

 

[marvdmartian]

My dad did it, and I do too. He told me if you keep track of the mpg, you get a feel for when your engine isn't running right, by noticing a drop in mileage (as was pointed out earlier in the thread, by lxskllr). Really no other reason to do it, except maybe to satisfy your OCD.

Eli, next time you have that sort of over-pump, you need to request that the gas station attendant shut down the pump and call someone who can check the "proof" of the pump with a 5 gallon prover can. They'll be licensed by your state's weights and measures folks to check the pump, and verify it's pumping the correct amount (and correct the adjustment, if necessary). Tell the station attendant that you will be calling your state's weights and measures department, and complaining about the problem (the number should be on the sticker that the prover company put on the dispenser).

If they've been notified of a problem, and continue to dispense fuel from that pump, and it's later proven that it was out of calibration, they can face some pretty hefty fines. Also, once the calibration folks run a "proof" on the dispenser, they'd be able to tell how far off it was from reality, and you can calculate how much was actually pumped (and how much the gas station owes you in return, for overcharging you).

 

[evident]

i do all the time. for the reasons above ^

 

[waffleironhead]

I used to, now I do not bother any more.

 

[zinfamous]

Only did that when driving cross-country last year, for tax reasons, and just to know.

But I do reset the tripometer every time I fill up. I keep all the info that I need in my noggin.

 

[IronWing]

I write the mileage on every gas receipt. When I download the CC info, I note the mileage for each purchase in MS Money. Once every few months I export the entries to Excel.

This pleases me very much.
