Fuel Tank is Too Small

[rocket23]

My commute kills any thought of gas mileage.......all city and most of the time is spent warming it up.the commute is 8 minutes.......1.5 miles with 5 lights and 4 stop signs.

Early miles on mine were all gassed up below 300 Range. Later, it got better. Most of the time my Range is between 310 and 320. The best I ever saw was on a road trip, one stage it showed 380 something, I forget exactly.

thanks for the reply. hb

fine almost 3 gallons ya don't have to yell,lol

Sorry, too much math training on my end!

I too like to get on it, maybe that's why I'm not getting better mileage, still amazed at all the power. But I really did not get it for the miles.. thanks for the input. hb

if you're doing mostly stop & go, and spirited driving, your gas mileage will never get over 20. Car weighs a lot and is really inefficient when accelerating, does great though when cruising. I've gotten 32 MPG on the interstate.

Temps going up will make a difference. Yesterday I averaged 29 mpg on my commute to work, it was 60 degrees out. Today I averaged 24 mpg, it was 35 degrees out. Same tank of gas and same traffic.

winter sucks gas.......and everything else come to think of it.

Don't think a temp drop of 25 degrees would make a 17% drop in fuel mileage. Never heard of such a thing. Engine runs at same temp in either weather.

Colder air is denser. More fuel will be injected... burns hotter = MORE POWAAAAAR

I’m not a scientist, but I did stay at a holiday inn last night.

But you said you got BETTER gas mileage at 60 degrees. I'm puzzled.

I honestly have no idea what you are talking about. Dis my first post in this thread homie. I don’t recall any post about 60 degrees and better MPG from me (In Any thread).

Oops. was replying (I thought) to someone who stated they got 20% BETTER fuel mileage at higher temps. Didn't make sense to me.

Still makes sense. If colder/denser air is compensated by the ‘puter ‘ by increasing fuel to maintain AFR, they more fuel would result in lower MPG.

So I wouldn’t be suprised that MPG slightly improves as temp increase (up to a point).

 

[Stingkia]

20% mpg increase with 25 degree temp increase? No way.

 

[nhcowboy28]

I said slight increase in my post above. Lol

I won’t stand behind the 25% increase until I have empirical data (getting an entire year out of the stinger) as I methodically log fuel consumption against time/tires/fuel grades.

 

[Stingkia]

That 20% claim was made by Doel above.

You get better fuel economy in hotter weather. Warmer air is less dense, that means less air resistance, less oxygen during combustion, less fuel used. That's why you get more power in cold air, more oxygen, more fuel, more power. Also when it's cold you use more accessories like heaters, defrosters, you may idle your car a bit to warm it up, that all takes energy aka fuel.

Let me give more detail on my not really experiment. The day before it was low 60s, probably 62ish, I didn't idle my car, I didn't turn anything on HVAC wise, I got something like 28.7 mpg. The next day it was low 30s, I had to turn my defrosters on so I guess it was colder, 31-32 probably. The car idled for a minute before driving, the heat was ran the entire trip and the defrosters for 10 minutes or so. I achieved MPG in the low 24s, let's say 24.2. My commute is roughly 25 minutes over 19 miles. So I saw around a 15% increase in fuel economy when temps were 30 degrees warmer. If I had driven further, I'm sure it would have been less.

how did you get that kind of mileage? would be interested to know your secret. thx hb

Live a block from the highway in a town with 4 stop lights. 0 traffic = great fuel economy. Lol.

You just described my commute as well. Just so I get some extra fun miles I actually drive 10 miles the opposite way in evening to get home. I get 15-16 mpg at best.

Just got my 2020 Stinger GT Ltd in Canada. I was VERY surprised at how small the gas tank is. My old car was 25% bigger (2015 Hyundai Genesis Sedan). I will have to fill up A LOT more often.

 

[MerlintheMad]

25% more often, and your car's profile is a lot more pretty than some old Genesis. Everything about the Stinger is a compromise. And the end result is Balance.

I think the people at Kia are geniuses ......more time(s) at the pump correlates to more interaction with the public...ie: what kind of car is that?!...which in turn means more sales...albeit one gas fill up at a time.lol
