Because the Doc didn't want to risk a cave in while trying to unearth the Delorean to get the gas. If they tried and caved it in, huge time pardox. Also, when Marty got there it was nine months after the Doc buried the time machine in a mine. The age and storage conditions of the gas could have severely degraded it making it useless.

I've had gas go bad in less than nine months before, it's possible. And there was no cave in because no one tried to dig it up. They could have dug it up and had nothing happen but then the movie would have been over too quickly. And Doc being a scientist more than likely didn't want to chance it after the huge mess they caused in the first two movies.
Here's a kicker...assuming Doc couldn't get the gas from the buried delorean, couldn't he alter that letter he wrote marty in the future and instruct him to put a can of gas in the back seat?
Then it would be like Bill & Ted's where you could do anything you wanted but you'd just have to remember to do it after everything was said and done.
nope, you're wrong, CrazyDe1 is right. it's just a plot hole. you can't try to analyze a time travel movie like this, it's impossible.

In the movie world, no. But I doubt Biff would have bothered returning the time mobile. He could have screwed Marty by stranding him in future(?).

Well, maybe.
Old Biff left 1955 after giving himself the almanac and went to 2015 where the unaltered timeline Doc and Marty are. Since he altered the original timeline the 2015 he left from was altered also. Now since Doc and Marty are still there things changed around them. They didn't notice anything had changed, or maybe nothing changed cept from the McFly's living there, anyway Doc got Jennifer out of the future McFly house preventing them from noticing anything. Now since the timeline was altered, that no longer was the future McFly house and if Doc hadn't got Jennifer out of there before Biff altered the timeline they would notice. HillDale undoubtedly still existed in the altered 2015 in one form or another so Biff still had a spot to return to and Doc and Marty still had a place to be.
Granted it may be a stretch and it takes some thinking to figure things out, but it can be explained.
Wait. Didn't that Delorean get USED up in 1885, and so when Marty went back, the timeline in 1885 continues, thus Doc would continue his existence without that Delorean. So it made perfect sense that Doc, being a brilliant man that he is, invented the steam powered time machine.

No, the delorean Didn't get used up in 1885 ...
The doc went from 1955 to 1885 in the delorean, then he buried it, and it traveled normally through the timeline to 1955, where Marty picked it up and used it to go back to 1885 after fixing it. It was still in 1885, and if the doc had wanted to he could have gone and gotten the fuel. to sned marty back, instead of the steam thing. Also, after sending marty back, he could have (being the genius that he is) figured out a crazy way to fix the delorean with 1885 parts, then gone to 1985 and made a duplicate time machine [say a Ford Festiva]. Then, so long as he put the de lorean back in the mine in any time after he took it to use and before marty picked it up, (say, using the two time machines) everything would be okey dokey.

It's not a plot hole. It just happens that changes in time takes time. When old Biff went back to the future, the changes hadn't caught up to him yet. Like when marty went back in the first one and interfered with his parents meeting, it took a bit of time before the ripple made its way to the future. That's why his brother disappeared first, etc. When old Biff returned to his time, he was really going to an alternate future but the ripple hadn't caught up yet. When Marty and Doc went back to 1985, they went to a time where the ripple had already passed.
About the DeLorean, someone who is planning to store a car for a few years, let alone a few decades, would know to drain all of the fluids out of it. What good would the DeLorean be in 1955 if the fluids tore it apart over the 70 years?

I assumed that the DeLorean ran via the Mr. Fusion from the future, NOT gasoline. Once it got fried after being struck by lightning, the Doc in the 1950's was forced to revert the DeLorean back to its pollution-creating, unleaded-burning ways in order to allow Marty to travel back to the 1800's.
This was explained in the third one. Mr. Fusion was only used to power the time circuits and the flux capacitor. "The internal combustion engine runs on gasoline, always has."

It's a plot hole. There are several holes throughout the trilogy. However, when I saw the first one when I was 5, I didn't care... and I still don't. 
There are also 2 Deloreans (and 2 Martys) in 1985 for a brief amount of time. Remember the one Marty drove back from 1955 in BTTF1? It was sitting in the middle of the street when he rode his skateboard to the Mall to see himself go back in time. That one gets used again by Doc when he travels to 2015.
If you think about this too much, you could create a paradox that could destroy the entire universe (or it may be localized to our own galaxy...)

At the end of Part III, when marty makes the jump to the present in his time machine on the railroad tracks, just as he appears and the car is slowly coming to a halt, look at the far right side of the screen and you'll see this bubbly mass of something. Maybe some sort of special effect or something? I've noticed that for the longest time yet I can't explain why it's there. Someone who has the trilogy should go check that out.
