99; 318; 4x4; 130k; 13" WIDE BFG Mud tires; 75 mph highway cruise.

with 15w50 oil in the summer average 17 mpg [5-8k on oil tests ok]
with 10w30 oil in winter average 15 mpg [3-5k and oil is shot]
With 5w40 oil in the winter, average 16.4 mpg [small sample, good for
5-6k miles]

I intend to run more of the Shell Rotella 5w40, as it tests as good or
better that the Mobil one, if a little less longevity.

Mobil 1 10w30/40 Good for 3-5k miles before being totally used up,
depending on driving.
Mobil 1 15w50 Good for 5-8k miles and still has reasonable life left.
Shell Rotella 5w40 Good for 5-6k miles, only tested twice, but it fits
solidly between the 10w30/40 and the 15w50. Depending on how it tests
in the warm, I may switch to this altogeather because the thinner oil
seems to quicken throttle response just a tad.

Side note, The benz runs 10k on 0w40 and seems to test ok, but I have
only sampled at 5k [no change] and just now at 10k [test not back yet]
