Check your math…

^^^ got it...my zero's were lacking.:)

Cruze TD. 15.5 gallons and 40-50 mpg depending upon speed and wind.

Was able to squeak out 620 miles in my 2016 Sierra PU. 5.3 and, I think, 24 gallon tank (might be 25). Temperature, tires, road conditions, and destination were all favorable.

My C6 will go 450 miles. My S10 will go just a bit over 200. Thats depressing.

My Leaf has 18,000 miles logged and I put 5 gallons into it once. But that was in a can for the lawn mower 😊
range is 73 miles 😔

When i fill my VW Touareg TDI it says i can go 700 and some odd miles. Never tried it ... doubt it would go that far.

Damn. The most I ever got out of a tank throughout the decades was about 300.

You have a big disadvantage. Living on an island there are no long drives, and it is all heavy traffic with pretty scenery. The total opposite of driving from Kansas City, to Denver. Mile after mile of whet fields and drive for two hours, stop at a rest stop, drive for two hours, and swear it is the same rest stop as before and you fell like the Twilight zone on an endless trip.

The entire island of Oahu is smaller than Oklahoma City proper. If I add in the surrounding suburbs the OKC metro is well over 1,000 square miles.

Jetta diesel.
Touareg diesel.
Both over 600 at 75. The Jetta was crazy economical.

It’s well into the 600s - even cruising at 80.

My 69 Camero with a 230 CI 6 cyl., traveled from Beaufort SC to P'cola FL on one take about 560 miles as I recall.

My 2021 SuperDuty with an aftermarket S&B 60 gallon diesel tank. Over 1000 when empty. Drops to 600-650 when towing.

My '87NA 944 (which I've recently rebuilt) will go around 600 miles on decent touring tires, just above 500 on performance tires, and close to 500 on Blizzak's. 21 Gal. Tank. Midgrade (89 octane) gas. Porsche Classic 10W50 for Spring/Summer/Fall, Castrol Edge 5W40 for Winter.

Edit: Above figures extrapolated from my own (mpg) mileage calculations at fill ups, and not from burning a full tank on one go, in which case I'd likely realize slightly higher mpg figures...assuming results from single day, 500 mile plus road trips, while the daily max. I've driven thus far is about 350 miles.

Almost forgot about it, but wife bought a new Audi A3 TDI about 2011 or so. That thing always did well over 50+ mpg on the highway and always over 600 miles on a tank (it wasn’t a very big tank) Plus, while doing it, it was “scalded ape” fast! Really liked that little thing. Audi bought it back from us during the “diesel gate” scandal. So what if the Germans had read the rules of the test and figured out how to use them to their advantage? That was a very efficient and very “green” vehicle. One of the stupidest, or perhaps one of the the most corrupt (obama DOJ shakedown for billions) episodes in automotive history.
