Real world MPG

[PA_RN]

How is your real world MPG. Are you getting or close to the advertised MPG or falling short?

Personally I’m falling short, averaging around 18.7 MPG daily driving in combined city/highway traffic driving in comfort mode with the auto on/off active. I was also averaging only ~21 MPG on an all highway trip with cruise control set to 75mph. Tires all properly inflated. There was some speed changes with adaptive cruise but nothing too major. Also I’m not accelerating hard and am past break in with around 800 miles on the car.

I just returned from my first road trip with my GT2 awd. Approximately 250 miles each way. On the way out dealing with some rush hour traffic but primarily highway I got a true (calculated at the pump) 21.7 keeping between 80mph and 85mpg with some triple digit fun [the trip computer read nearly 25mpg]. On the return trip the computer read 27mpg - I did not have a chance to do the at the pump calculation but would assume it was around 23mpg.

I am very interested in this thread. Please anyone posting here do exactly like MarcMIA and let us know if you're going by the Stinger's estimated mpg or calculating the real-world mpg at the pump. My Optima's estimations are usually around 2-2.5mpg off the actual result, so Marc yours being 3 isn't too far off. 18.7 with highway mixed in seems horribly low.

That’s why I’m trying to get some results to compare it to. I’m wondering if something is wrong with the engine or computer. Bad spark plugs, programming issue, anything. It seems to drive fine except for the poor MPG. I got almost exact same MPG on my last car with a 5.0 liter V8.

In light morning traffic and with ~20min of my 30min commute being highway...I’m getting around 26-27mpg.

I’d say it’s close, but I don’t fair too well on the city mpg.

Took a morning session from two days ago and I was doing between 60-72mph for most of the highway trip, but some slow downs and near stops.

I wasn't getting anywhere near the EPA estimates until after 1500 miles. I'm now at 2500 miles and it's MUCH better, even with me driving much harder. I took a trip recently and averaged over 27 mpg, with the cruise set at 80; I refilled after 380 miles with about two gallons left. Mixed highway/city driving returns about 23 mpg; I can squeeze about 320 miles from a tank before I refill.

These are marked improvements over the numbers I got when it was new. I couldn't get over 300 miles from any tank, and averages hovered at about 19 mpg mixed and 21 highway.

Give it time, it gets better...

Just filled up after 278 miles and got near 28 with a mix of freeway and stop and go, probably 70/30 or 60/40. 2 liter engine. Two freeway trips of 65 miles got over 30. This is going 70-75 and with the hills here in western NC. ECO mode only. Going to try comfort mode next.

While I'm not a fan of notating every badge on the Stinger you've changed into your post's signature, this thread has proven how useful it is for people to add what trim of Stinger they own for a quick reference like in Bear's post. A good feature I'll be sure to implement once I've got one.

I drive a base rwd 2.0. When its cold i definitely see a drop in mpg. I'm STILL breaking it in, so my overall mpg isn't reflective of how it'll be once the break-in period has passed and there more than 1000mi on the motor. That said, I did try to go easy on her dropping off my son to daycare, using only city streets, and ended with this:

 

[mldavis2]

I wonder how accurate that is...

 

[davebo]

Well between my Optima and Marc's Stinger GT we've got two cases in the thread of the trip computer coming up around 3mpg optimistic, so even if Rufus is getting real-world 31mpg that's pretty good.

 

[Berzerker]

I'm at 1250 miles and it was *much* better than at 1-200 miles. Every fill up my total range went up 10-15 miles. I'm at around 340 miles on a full tank with an average of 22-23mpg. I suspect it'll continue to creep up for a few thousand more miles and settle.

My first fill up told me I had 265 miles on a full tank, and was getting around 18.5-19mpg average.

 

[Vaoh]

I find my average with a close to 50/50 driving is about 27MPG with the 3.3TT. This is calculated between fill ups and not so much off the onboard computer calculation. But I find the computer is really close to what my real world is, so I'd say I'm doing roughly 24-25MPG city and highway is between 27-31 totally dependent on speed and what the freeway is like. Doing 65 on flat road it'll do 30 or so MPG easy, 75-80 when it's hilly and you'll do about 27. This is in Eco Mode, Sport Mode does end up with what the EPA ratings are though.

 

[Rufus]

I wonder how accurate that is...

Even if it were off by 20% that would still be over 27mpg for city driving. And, as mentioned, I deliberately took it easy expressly to see what mileage I could eke out. Basically, I drove it how my wife drives her Prius lol! Lucky it was early and no one was behind me or I'm sure I would've gotten a few choice honks

I’ve been honked at once but only by someone with a smile and a thumbs up! Didn’t get to see if she was blond or brunette unfortunately.

I posted this somewhere else but over the last 4 or 5 tanks, my MPG calculated by the car and my actual calculations have been either identical or within 2-3 tenths of a MPG. It appears that the car's calculations are pretty accurate. my average mpg per tank in cold winter weather and mixed freeway and city driving has been around 22.5-23.5 mpg. I expect it to go up a few MPG in the summer months. I haven't done a long trip yet so don't know what the highway MPG is.

Again, it'd be helpful if people either mentioned or added to their post signatures what sort of Stinger they have so we know if you've got the 2.0l or 3.3tt

 

[Jaystinger]

3.3 here I have 350 miles on it and I average 17.5 on city 24 highway. Comfortable moe most of the time. Fill up reads 260 on fill up

I'm going to start two "official" MPG threads right now. People can check in and report - or not. Make it useful, or don't.

GT2 AWD with 18" wheels and all season tires (3.3l). I've had it for about 6 weeks and 1800 miles.
