Well at first I thought that's not enough gear to be able to use your 5th gear, but then realized that a 2.2L was the Isuzu diesel (1985).
With whatever factory gear they came with (was often 3.73:1 or 4.10:1), the old EPA rating for highway was 36 mpg, and the new rating is 33 mpg, so that's really not that far to go.
I would say that it's very possible.
The 1985 model was not heavy.
Diesels handle the extra loading from the gear superbly, and you just might realize a very efficient combination with it running at such a low RPM at speed.
Compare Side-by-Side
Edit: maybe you meant the 2.2 Vortec SFI ?
Sorry If I got confused.
