Fill-up #14
since your last fill at 44,742 km
what this tells you
13.7 km/L↓ 1.1 below your average
That drop costs you ₹6,369 a year.
My father notes 4 values every time he refuels: odometer, price, litres, cost. He has never missed a single fill-up. But the issue? He writes it down on whatever paper he finds. And most of the time, that paper gets lost.
Why we built this
My dad writes down every fill-up. Then loses the paper.
I grew up watching my father do this after every single fill-up - without fail, for years. The discipline was always there. It just never had a home that couldn't be lost, torn, or thrown out with the car. That's the only thing TrackMyTank changes.
Everyone has got a theory
Everyone will tell you why. Nobody actually knows.
Ever since E20 showed up at every pump, everyone has got an opinion about why your fuel efficiency dropped. None of them have seen your car's numbers.
Mechanic
"Could be the injectors, hard to say."
WhatsApp forward
"Mileage dropped 30% after E20, confirmed."
Petrol pump chat
"This brand gives better mileage, everyone knows."
Friend / colleague
"Check your tyre pressure first, honestly."
Family group
"That other brand is more reliable, in my experience."
YouTube comments
"It's your driving style, not the fuel."
Six opinions, zero proof.
Track a few fill-ups and you'll have real numbers instead.

Before you ask
Questions, answered plainly.
Do I need an account to start?
No. Log your first fill-up with zero signup. We only ask for an account after, so your data doesn't disappear if you switch phones or clear browser cache.
Is TrackMyTank free?
Yes, the core app is free, always. No paywalled tracking, no ads.
Does it work without internet?
Yes. Log fill-ups offline; everything's there whenever you open the app next.
Will it tell me if E20 actually dropped my fuel efficiency?
Not retroactively since we do not have your data before the switch. Start logging today, and you'll have real data the next time anything changes. However, if you have your past data and want to import that to TrackMyTank, please reach us out to [email protected] and we will get your data imoported in your account.
Is fuel brand comparison live yet?
Not yet, but it's on the roadmap and coming soon.
Do you sell my data?
No.
Can I track more than one vehicle?
Yes, cars, bikes, or a whole family garage, tracked separately.
Can I delete my data?
Anytime, completely. Just drop an email at [email protected] with subject 'Account deletion' and include your logged in email id. If you did not login to sync, then no data is ever saved with us.
