Hyundai Genesis Real World MPG
I'm in the process of deciding on the 6 or 8 cylinder and am curious how current owners are finding the mileage on both compared to the official MPG ratings on these engines. I haven't seen many comments on this so hope to get your feedback soon.

The 31.8 mpg value is measured from downtown Houston to Lewisville (Dallas surburb).
The "reset" button was pressed so the count was 0 mpg.
The car is set to cruise control at 65mph.
Average mpg is now at 23 mpg. I have remarkably short drive to/from my work place. 23 mpg figure is good based on the fact that I go through many traffic light in the commute of 4 miles.

My previous 1998 V8 Lexus GS400 did 17.5 and 24 mpg (and highway mileage was measured at 80 mph).
I will not have it out on the highway til this coming weekend, and I should have waited to report, but will next week, after a 600 mile round trip. I am gratified by this improvement, and am startled by how much better than the rating it is. Usually I have to baby a car to get the rated MPG, but as of now that doesn't seem necessary.
Of course, my measurement of every tankful is indicative of my OCD, but I'm stuck with it, and sometimes the news is good.
I traded in a VW Phaeton for the Hyundai. Loved the Phaeton, but hated the OHMIGOD maintenance requirements. That car, babied, did 15 mpg about town, and 20 mpg at 80 mph cruise controlled. I had guilt about driving that car, and fears of $5 a gallon gas making me miserable if I had kept it. I dare hope that my highway mileage will improve to near claims.
There was a new MPG system put in place about two years ago that makes the teting much more like real world driving. It is much easier to beat the new EPA estimates than the old (somewhat) optimistic #s.
For example (from fueleconomy.gov) a 2006 Avalon was originally rated at 22/31 25 overall on the new ratings system its 20/28 23 combined.
Your MPG seems spot on in your Genesis. My 09 with a tick over 10K is averaging around 20 in all city or gridlock highway.
2023 Mercedes EQE 350 4Matic / 2022 Ram 1500 Bighorn, Built to Serve
So average both ways was 27 mpg, right on the number, and that was doing 80 mph on open highways. I am starting to believe the hype about this car.
Since the car is actually larger than it first appears, I consider this mileage for a car this size, this powerful, rather remarkable.

I am pleased to hear I have more improvement to look forward to, but the 22.5 mpg in the city seems surreal to me, given the size of the car. I hope to one day post how right you are.
By the way, I am continuing to use regular gas, though I once did fill up with 93 octane, and I had no doubt I could feel the difference in performance. I would like to take a blinded test, though, so as to KNOW that I can tell the difference, or if my expectation led me to "feel" the difference.
Has anyone else made that "seat of your pants" comparison?
It would be a lot harder to drive your car to nearly empty, add one gallon of regular, do speed runs in two directions, then finish off the gallon as much as you dare, add a gallon of premium, and repeat the test at the same site.
Is that OCD, or what?

There are few misconceptions greater than there is between reg and premium gas.
Here are the (rather simplistic but) basic facts.
- There is more BTU in regular gas. If your manual calls for regular, do NOT use hi test.
- Hi-test has less BTU (energy) in it. Hi-test is design to have a higher (read slower) flash point. i.e. it is meant to be burned in combustion chambers which have a high compression ratio. Fuel ignites easier the more it is compressed. That is why older cars that have carbon build up in the C chamber, (which raises the CR due to its basic volume sitting there) often don't ping and run on when owners switch to mid or hi-test. You see....it is the red hot carbon that ignites the gas when the ignition has already been turned off, and hence causes the dieseling or run-on. Because the regular gas has a lower flash point (quicker to burn). So that is why hi-test often eliminates ping and run-on.
- there are no more deterents or additives in hi-test than there is in regular.
- if your car is designed to run on regular, it will have more power, and run more efficient to boot. (no blind test required)
- upper class luxury vehicles (and some lesser ones) often use a detonation device that operates electronically. It can sense regular gas if an owner uses regualr gas in a car that requires premium. But this only fools the engine into thinking it has the proper grade gas. It makes adjustments to engine timing etc to do this. But owners of cars that require premium should switch back as soon as their next tank. Running hi-test in a car that requires regular, actually tends to strangulate the engines ability to perform as manufactured.
- because fewer owners purchase premium at the pumps, it is always older gas. Makes sense right? So again, use regular if your car is designed for it.
I am amazed at these MPG figures real world owners are getting, and I really enjoyed seeing some of the detailed write-ups here. Very impressive.
I am in the market for a Genesis I think. But I am sorta poor and need them to depreciate a little more before I can find one I can afford. Was the first year 2009? Did they have any issues? I sorta hate to buy first year of anything.
If anyone here (non-smokers only please) decides to sell their (V6 only) any year considered, Genesis because their needs change, send me a message here or PM. My notifier is turned on. thanks

Anybody else validate this subtle exaggeration. I am getting 22-23 MPG but trip computer says I'm getting 23-24mpg.
P.S. Please don't think I'm not taking your problem seriously, if we buy something it should work as advertised. Good luck.
