Sharing MPG Data for those interested

SMART mode seems to give the best mileage.

Finally finished our first tank of gas. 28.9 mpg which is pretty good for us since our mazda that we returned only gave us 24 on our best day. The car is still breaking in, and like most cars you don't see amazing gas mileage until about 1000k or more. I can see this being around 30-33mpg for our spirited driving style

Highest I managed was 32.1 on a road trip to Seattle

Well i am running a KN intake filter on the seltos. Not sure how much of difference it actually makes since I never really tested the stock filter. I have used KN filters in almost all my cars and noticed they make more of difference in turbo charged cars vs NA. Wifes mazda which is NA never a made a difference and also never made a difference in her bmw which was also NA. My subaru ascent went up 4 to 5 mpg and my wrx also went up similar numbers

Putting the model you own in your profile or your post helps make mpg numbers more meaningful. My SX had a best indicated mpg of 34. Typical is more like 27.

Done but for record. Kia seltos sx starlight yellow. My first drive consisted of switching around normal, smart , sport modes. New drive will be only smart mode

Perhaps I shall have to look into the K&N filter for my SX Turbo. I've been tracking mileage at each fill-up using CarFax app and the average combined is 26. Typically I leave the Drive Mode in SMART unless I ned to get up and go to merge with freeway traffic as some of the on-ramps near me are really short. If a K&N filter give 4 more MPG, on a 11 gallon tank, I'll take it.

This first tank was just tester and numbers were taken from trip computer. Wife did the current fillup so and she never took down how much she filled up with so i wasn't able to do a proper calculation but ill do it on next fillup. Unfortunately I threw on thr KN filter early so I'm not sure what the mpg difference will be and if the difference will be consistent. On my subaru ascent the difference was consistent and averaged around 24-26mpg with the kn. Recently had a slipping transmission and threw the stock filter back so can't blame it on that and I've been driving around with stock filter ever since. Averaging around 20-23mpg but had a terrible 19mpg tank this last week which to me justifies throwing the KN filter back on

I have 4000 km on my Seltos EX Premium 2.0 litre and have a running average of 6.4 L/100 km, which is about 36 MPG. That is about a 50-50 mix of highway and city driving. We keep it in smart mode.

My 2021 Kia Selos SX /w Turbo 1.6 & DCT has been on two road trips and some around the town now over the last 6 months-ish. One trip both ways between Pensacola, FL and Atlanta, and one way from Pensacola to Grand Junction, Co. (enjoying the mountain area today).

5671.6 miles @ 32.7mpg, timer 99:41hr. I estimate 2250 of that was highway and the rest around Pensacola. All 'Smart mode' except normal for the first 300 - and probably 30 miles in 'Sport' while testing 'passing' in the Colorado mountains.

After reading this post and many of the comments that followed regarding gas mileage I saw mention of smart mode and sport mode too. Isn’t a big factor in mileage per tankful, the speed at which we drive and accelerate too? If we are traveling 15 mph or more above the speed limit I would expect gas mileage to suffer a lot. Using cruise control on open highways really seems to help too. On a side note, my first break job on 2016 Kia Soul Base was at 88,482 miles and my trusted mechanic said I didn’t even need to do the brakes yet and had more time. I did the brakes anyway and got brand new rotors too. I get those results pretty much with all vehicles that I drive. So I think the way we drive and the speed we travel at is a large factor in our gas mpg calculation.

Fillup-Gas Mileage Log by William D. Kreamer is a great app for keeping track of your gas usage and MPG.

I'm getting about 32mpg after 5200 miles on a 2.0l engine with AWD and CVT. I hand-calculate the milage using the odometer and gallons at fillup.

Don't trust the mileage computer - it's garbage. Mine reads 2 to 3mpg above actual.

Same here. I manually calculate the mpg at every fillup. I concur with your observation that the mileage computer is off by 2 mpg. During my first 1,000 miles, the computer always showed 32mpg. So I said “wow” that’s nice. But when I started keeping tab of the manual calculated mpg, I always get 2 mpg lower than what the computer is showing!
