To add to the broader diesel discussion, I can easily get between 33 to 39 mpg CONSISTENTLY (I can see folks now rolling their eyes, or for some, shouting BS) . I do not, as I have been defacto reporting. In effect, I chose to run the TDI at its optimum and optimal levels, as much as I can.
Now, since the most likely scenarios are you keeping the vehicle 39 mo's (3.25 years) and app 39,000 miles, it is really your (anybody's) choice how it is run. Miles UP to that (starting at 35,000 miles) and beyond, it is easy to swag you will probably not care very much.
Indeed optimum mpg really does not happen (full compression) till app 30,000 miles (if broken in slightly to semi aggressively) to 60,000 miles if "babied" to slightly aggressively) . There will be a good chance you will not experience optimum mpg during your term of ownership !! As a sidebar: from 31,000 to 60,000 miles I can probably now expect even slightly better mpg (app 1 to 2 mpg) as the other TDI's have historically done.

Some grocery stores have fuel bonus points you can earn, up to $1/gallon up to 35 gallons. There are some easy tricks to get the $1 off gallon.. Fry's (Krogers) and Safeway are two of the easiest stores to do this.

I drove 443 miles and averages 21mpg (75% on the highway), what is interesting is the following week I rented a Ford Escape limited with 22 miles on it, it had the 1.6l turbo engine, and I averaged 23mpg. IF the GLK250 would average say 30, I would be happy, but one has to wonder if MB would retune the engine to make 180hp and less torque would the engine get better MPG?

If one is ultimately intersted in a MB, specifically GLK 250 Blue TEC, why wonder? I am sure if one roots around one can find those that do and will specialize in MB "CHIP" tuning. I do have to say most (users/customers) chip for INCREASED HP/Torque and specific performance parameters, mpg falls where it might. The code sentence here is: "IF I don't get on it, fuel mileage is same to slightly better." But hey, tuning for max mpg can be a performance parameter in and of itself.
Off topic and probably TMI: my 03 Jetta is (VAG.com) tuned more toward performance, even as it is bone stock. But even 185,000+ it has no issues posting 50 mpg. It can easily post 59 mpg, if I keep 75 mph with occasional bursts to 85 mph.

Right now it seems that EVERY MB GLK 250 in inventory are loaded with any array or combination of options. This has the effect of making any MSRP much higher than the standard accessories $ 38,590. Indeed the one I test drove was app 52k and they were dealing app 48k +. Another is if you like any other color (of 12) than black, white and red, the minimum bump is $720.
I have to agree with you, however, this was not the case a month ago, here in Phoenix two of the MB dealers had basically base GLK250s on the lots, MSRP was $42K, today, fully loaded prices between 48 to 52K, ouch....

Best I have done with Safeway ULSD is get .50 cents gal off. More normal is .20 to .35 cents. So what are some of the tricks?
Off topic USLD local is 4.11, In a resort town 3.79. (Diesel) RANGE will let me pretty much fuel anywhere I want. So for a 26.4 gal tank with .32 difference that is a savings of 8.32 per tank. If I get .20 cents that is another $5.20 per tank. TMI is : I also get 5% on the CC so that would drop another .19 cent a gal or -4.93 per 26 gal tank full.

I think I managed .28 cents off one time with our local IGA program. I probably could get more but they changed the program so you have to buy what's on special to get the discount and that stuff is often junk I don't use or eat.

This is done with gassers also, but in the context of this diesel thread, this gives diesels a bad name. Most of the stuff that is included in these options, I don't want or is marginally useful at BEST: gasser, diesel, hybrid, plug in electrical etc.. Now if one is of the opinion they (these options) are the epitome of best thing since sliced bread, it's good, albeit, way expensive. One will come to find out, it hikes the per mile cost of ownership/depreciation WAY WAY higher.

If for example, you know the weight of your gasser's engine, normally you are WAY past TMI and know how to get the TDI's engine weight.
To use one like model snapshot, a VW Touareg V6 gasser tips the scales 4,711#'s. The TDI comes in 4,974 #'s or 263#'s heavier. (PLUS + 5.6%) The gasser posts 265# ft of torque, the TDI posts 406 # ft, for 53+% MORE # ft of torque. For a (like model) gasser to post the same torque as a diesel would almost require thousands more in upgrades and mpg would suffer all the more. This of course would add weight, which is unknown on an aftermarket basis. So while in this (real world) example, 263 #'s is an "exact" number: how it is EXACTLY distributed does NOT jump out. It is of course easy to swag that components taking a lot of stress get bulked up.
Needless to say, if the TDI can be lighter ( MINUS-263 #'s, aka same as a gasser), it should get even BETTER mpg. OEM's seldom (if ever do a weight/per component breakdown, even in OEM shop and technical manuals, let alone a gasser/diesel comparison (probably opaque to maintain/shield proprietary design data). So data searches are a bit like looking for needles in a haystack.
Then TDI's from a mpg perspective, are even more impressive as TDI's carry both heavier weights, posts way higher # ft of torque, and STILL gets better mpg than like model gassers.
