Hey guys ... a buddy of mine records his gas fill ups every time he is at the pump, and I decided to start adopting the practice.

1590894875092.png


These are the current columns I have. The mileage (or km's) / date mix is a nice record of the type of mileage I'm putting on the bike throughout the riding season, while the mileage / gallons mix is a great way to average out your miles (or km's) per gallon.

My bike only alerts me when I have 1 gallon left in the tank, so to know I'm averaging ~48 mph with my current sample size is helpful. For example, I rode a bit over 20 miles after the light came on today, and it matches nicely with the 3 gallon fill up on a 3.6 gallon tank.

One of the other perks of doing this that I can see is that if the bike starts to run poorly, I may see that reflected in the average mpg between fill ups. Obviously I have to factor in the context of running the bike hard, city riding, etc. that could also be the cause.

Anyway, thought some of you might find the practice useful, too, or have other ideas/opinions on such a "log".

Best,
~ Humes

I do keep the receipt, with the idea to maybe once check it out.
But never really do xD

I know what he does on average a bit, and know that certain ridestyles means i won't get 240km out of a tank xD

I personally use Fuelly, also has a phone app. I find it really useful, shows graphs, avg miles per tank, etc. You can track services and tyre purchases as well.

I used to use a phone app,can't remember what one.... but I kept on forgetting to fill it in and never installed it on later phones.
I guess it could be kinda interesting to have a record of mileage from different tyres! :)

If there was a phone app that could read the receipt and fill it in automatically, that would be amazing.
So date and litres tanked (maybe even price).
Then manually add kilometres (or miles) ridden and that is it...

Then maybe, yes.

I just use the trip meter. Reset it every time you stop to fill up, and make sure you fill it up full. When the trip meter gets close to the range, you know it's time to pop back in for a fill up.

I'm not concerned about how my km/L (mpg) is, I never believed nor cared about how great someone can make their mileage go at the brink of running dry, because doing so stresses your fuel pump out, those pumps ain't cheap to fix or change, so I rather have my tank filled up before reaching critical levels and keep my pump happy.

I've heard this called the poor mans fuel indicator, but uhm both my Ducatis had no fuel guages. Its only my Triumph that has a fuel guage.

I've done this for all of my bikes from time to time just to measure what MPG they are actually getting, but I don't do it always. My Goldwing tells me what mileage I'm getting and it's accurate from what I've measured, so I don't even bother tracking it manually now.

My understanding is that the bikes that generally don't come with fuel indicators are performance (or race) orientated bikes, because in the track you are more concerned about other input like RPM/gear position/etc than looking for the fuel bar.. LOL..

I used to somthing an app but I have a terrible memory and forgot to fill it out. The thing I like about my CB500X is that the computer does tell me mpg in real time and on the trip.

I have the Fuelly app, but don't always use it. My bike doest have a gauge either, but I just go off of trip distance. I know when I get to 100 miles on a tank, I should start thinking about finding a gas station. The low fuel light is supposed to come on at .7 gallons left, and so far its been accurate, but Ive only had it come on twice.

I work it out from time to time. Normally when I make some sort of change to the bikes to see what its done.

Other than that I really don't care.
