I decided I'm gonna start logging my gas information at each fill up. I put on the top line: Date, Grade of gas, Gallons Purchased/Used, MPG, Miles on tank, and the Total Price. The last tank i bought, on 9/17 i bought 93 octane, purchased 10.9 gallons, had 207 miles at the time, making my mpg 19, and it cost $30.67. Anybody else do anything like this, I think it should help me keep up with mantienence and gas price fluxuations and what not.

 

I've been keeping a log also. Initially, it was only to keep track of how much gas was used because my fuel gauge is not working properly. I've recently begun calculating my mileage in the same you have and was surprised to have gotten 21.5 mph on my last road trip over the weekend, which was mainly highway driving.

I'm keeping an official log as of two months ago since I have to budget for gas now. Alos check you tire pressure once a month since mine rear right dropped 17 psi in between my monthly checks and that can really hurt MPGs.

 

I use this for tracking all of my vehicle information

Its free to track one car, its a little annoying though because it reminds you this every startup

 

looks interesting, no windows version......oh well. Not worth bugging them over.

 

I write out manual logs with every fill up.
Been doing it since Nov. of '98 when I got the 4Runner.

 

I have been keeping track of my gas mileage on MS Excel since last August.

 

I also use a spreadsheet that I did up in Excel. I log similar info as you, but it also keeps track of total mileage of the car (by adding miles driven between fill-ups). That total mileage number gets used on the "maintenance page" of the spreadsheet to automatically pop up reminders for the periodic maintenance that I have to do (oil and filter changes, fluid flushes and changes, belt inspections and replacements, brake inspections, sensor and throttle body cleanings, etc...)

Everytime I perform maintenance, I enter it in that same page, and it automatically resets the reminder to the next time I need to do it (based on the interval that I specify for that particular maintenance item).

 

i don't like figuring how much more i spend on gas every year. if i had kept a log of what i was paying in 2001 and 2002, looking at it today would make me cry...

i do like to keep track of how many miles i'm getting to a tank, i write the mileage at the fill-up on my gas reciept, kind of like a crude trip odometer, since my truck doesn't have one.

 

I track it all in a green, quad ruled, lab (composition style) book. It doesn't leave the truck and in it I track gas mileage, maintenance items, mods, upgrades, etc. I also sketch ideas down for the truck and keep some phone numbers and other info in it. I've also found the green tinted graph paper to be easier on the eyes in full sunlight than the bleached white paper.

It's handy when used this way, as an empirical record of your modification's impact on vehicle performance and gas consumption. It can also be helpful in tracking down problems to specific dates or maintenance items.

 

do you have any blank spreadsheets in that layout, It sounds like a novel idea, If I had a little more of a template to start out on, I know I'd forget alot of things if I didn't have everything listed. Seems like I usually do mantinence whenever I get the preminition to do so, my in brain mantinece reminder isn't very accurate, something in excel would work great for me.

 

I can save a copy, blank it out, and send it to you if you want. PM me with the email to send it to, and I'll try to get it to you this week.
