I know I am for real, I don't think I have ever seen below 45mpg. 90% of my driving is on the highway, at the speed limit. High speed kills... your mpg's, low temps kill your mpg's, stop-n-go kills your mpg's. I also run my tire pressure at 38psi. I am the only one who fills my car, I do find that my mileage is still improving with 60K miles on the car. In the winter my snow tires kill 3-4 mpg's. All my fillups are posted in my fuelly account.

I'm for real, but I'll clarify that my best tanks have been in the low 50s and are more commonly in the mid-high 40s. My lifetime average (23k miles) is 46.7MPG based on fuel receipts, and that's with me driving ~74 highway miles every day. I usually do >50MPG on my long highway commute, but shorter trips result in MUCH lower mileage. If you check fuelly you'll see there are plenty of people with mileage like yours, so don't despair. Also, check that you're looking at the right average consumption--if you hit the OK button you'll toggle between average over past 9,999 miles or during the current drive. If you're only getting up to 40 MPG on a long highway drive, that may be the longer average (which actually varies a lot more on the MFI than is realistic if actually looking back over 10k miles).

Thanks for all the comments. The only fuel consumption indications I watch are the ODO and the gals at the fuel pump, then divide. In 21k miles I've calc'ed and recorded all but 2 tanks. Sweet spot 36-38. One thing that has bothered is some ignition miss in the first 10 minutes partic when moisture is high, and temp is cool. It's really subtle....can barely feel it, mainly at lower RPMs with no throttle pressure. It's made me wonder whether its impacting mileage. Dealer said it might be turbo warming up. Anyone felt that miss?

To throw in my .02, I have seen mileage numbers in the mid-upper 40s at speeds toward the 80ish range on several long distance trips. Best ever was 60mpg with considerable effort, but traveling around the speed limit it isn't uncommon to get around 50 mpg. I can't comment on city driving as I rarely do it, almost all of my driving is highway with light traffic.

Thumbs up

With a little extra attention to conditions you can see better mpgs city than highway......

If you watch traffic conditions not to over accelerate just to have to slam on brakes.

If you get into the highest gear possible sooner than later, at speeds above 35-38 mph when terrain allows(~1,100 rpms or higher if no acceleration is required).

Light throttle, give time to accelerate to desired speed. Especially when the engine is cold which is when they use the most fuel. Skip gears not needed and get into high gear & stay there as much as conditions allow....

Don't push the thing up the hill, allow your speed to slow slightly while going up a grade.

Along with using N on down grades as much as conditions allow as fuel if you have terrain of a few hills you can see much higher mpgs city than during sustained higher highway speeds. Many times you can use a pulse of energy then let gravity get you up to the speed limit(up to your desired speed) saving fuel.



I have ~38 years of records in all kinds of gasoline and diesel powered offerings to prove that the above allows maximum mpgs to be seen on city/urban tanks......

______________________________________________

I had to get a full size chevy pickup a recently and using the above techniques I was able to push mpgs up to 17 to around 20 running around the urban area. Talking to the previous owner the way he drove it over the last decade or so it would have been 11-13 mpgs maximum if he clocked those miles the way he drove.......
