'09 Unlimited, 56,000mi., little oil consumption which is somewhat a concern, uses 5w30 Mobil 1. No engine issues thus far although the clutch is starting to feel a little wimpy recently.

A little over 26K on my 08 JKU with the 6-speed. No issues so far (knock on wood). Planning to change all of the fluids (transmission, transfer case, differentials, etc.) at 30K so I should get a good look at how things are wearing at that point. Engine doesn't burn appreciable oil. If I run 5W-20 it comes up less than 1 quart shy at 3K. Even less is burned when I run 5W-30.

front crank seal, oil pan gasket at 58000
eats 2qts per 3000 miles still
trans cooler lines blowing everywhere at about 50000 along with power steer hose/bottle
ball joints at 55000
i've had nothing but jeeps since i started driving (my fourth),this one gets compliments about how it looks and what not, however mechanically and engine power wise i am completly dissapointed
