18mpg in a '91 Caravan, 2.6 Mitsu engine, antediluvian 3-spd auto - no fanciness whatsoever.
That was fully loaded for a long trip; it cost a lot in gas, but there was a lot of tailgate camping and it saved us hundreds of dollars of hotel charges.

My '76 E-250 with its 460 CID carb'd gas engine and no overdrive never got very good FE, but in the summer of 2003 I towed a 24'x8.5' enclosed trailer ~300 miles from near Bakersfield to near San Francisco against an advertised 35 knot headwind. When I got home I had averaged 4.9 mpg.
That's when I decided to buy the Excursion!

9.5
Worst MPG Rental: 9.5 MPG in a Ford E-450 high-cube box truck (moving van) and 4000 lb. cargo (gas engine).
Worst MPG Work vehicle: The easy answer is a Fire Department tanker, but we never really calc'd the mileage.
Regular work driver of the past: 1993 Ford E-350 "Van-Conversion" Ambulance -- Diesel. Depending on cruising or full-throttle response -- the 1000's of miles probably averaged 12 MPG. We'd calculate mileage during fill-up at the end of the shift, but not always. 4-years (full summers and most weekends of the same vehicles). Lots of idling, city driving, and inefficient acceleration.
Otherwise, about 15-17 MPG combined in a 77' Olds Cutlass in my own vehicle.

Dude - driving those things, I don't care what your mileage is so long as you get there. Emergency vehicles get a bye in my book.

I've never been much below 30 mpg as I have always owned stick vw diesels. My worst mpg ever would have to be when I was coming back from a canoe trip on the Kipawa river. I wasn't tracking mileage at that time, but 90-100 mph with a canoe on top of the 91 jetta TD for roughly an hour on route 117 through La Vérendrye Wildlife Reserve surely wasn't helping FE.
Unfortunately, I'm about to set a record low with the new hyundai during the break-in period.

6 mpg driving my dads old big off road truck towing a trailer around 60 mph trying to get better mileage.
6 to 9mpg driving the bus i used to drive not caring about mpg.
…Or maybe my old 86 ford when the fuel tank rusted through. Leaked 24/7!

I was getting just above 4 mpg in a Kenworth 880 tandem with a 3,600 gallon water tank and was spraying with the PTO engaged at around 5 mph and near redline, around 1,500 RPM.

0 MPG when I got the Subaru stuck in the snow with 3 girls and my friend while we idled the car to keep the gals warm as we spent 4 hours digging it out (twice). Turns out getting stuck going uphill is one level of problem, but getting stuck going downhill is a whole other level.
