Dan what's your fuel mileage like so far?
I'm also intrigued by how you do find good fuel, is it hard to come by?
On good roads, keeping my speed to around 50mph (which is only possible on the best roads) I can make it sit right on 20mpg.
I have verified the distance with GPS and hand-calculated that, so I know it's accurate.
The computer is optimistic for the first 1/2 of a tank, then comes into line by the end of it.
This is after 569 miles without a gas station:
On gravel roads it will sit around 16 or 17mpg. On nasty stuff with mud or sand it will go down to 11mpg.
If I had to guess, I'd say the entire trip average is in the 16-17 range.
Gas stations are very common, and I always try to fill up at the biggest, brightest, most used ones.
I have had no problem finding gas and the Jeep seems to burn it just fine.
(Other than in the Rep. Congo where there was basically none due to the refinery being turned off).
All in all, the myth about not being able to drive a gas vehicle in West Africa is complete nonsense. I have met multiple people doing it.
