Which MPG do you go off of?

[Hatche90]

I noticed that I have three different MPG readings on my truck and I was curious as to which one you would go off of?

The first image is how many miles I’ve put on the truck since I’ve purchased it (used of course).

The second picture is how many miles I’ve put on the truck since it’s last oil change.

And the third picture is the Overall average in a 400 mile range setting.

I know that I should calculate the usage from the time I fill up the tank to the time I refill the tank. However, I was curious to see which one you would consider to be the most accurate on your truck.

Hand calculator myself, but I was a data nerd that loves tracking it!

I have two trip meters. One I reset every month. The other is reset when I fill up. I hand calculate and found it's fairly accurate compared to the trip meters. I also reset my 50 mile meters every fill up.

Good point, I've always reset trip 2 for whatever reason, and use that for a visual between fill ups.

I’ve been meaning to try this but continue to slack on recording the data for calculations.

Is your monthly and fuel fill up meters pretty consistent with each other?

They are close but I would expect it to be different since driving conditions can change throughout the month. It will depend on how much driving you do. Around home, I only fill up about twice a month. On road-trips, it'll be more of course. Weather can have a big impact also. I'm noticing about a 2 mpg drop due to colder weather. Time will tell since I only have 6 fill-ups in 3546 miles but it's trending like I expected based on past experience in previous vehicles.

What I do if I'm in a hurry is take a quick picture of my odometer and and my receipt so I can go back later and add it.
