I recently have noticed a drop in my gas milage on my jeep from 260 to about 240ish some times less per tank......i run a 4 inch short arm lift and 33 inch tires its a daily driver and just wonder if any one would have suggestions on where to start trouble shooting this or if its just something that happens over time.

Thanks,

How long have you had the 33's? Did you account for the speedo being off, or replace the speedo gear when you put them on? Also like JD'sDream said, warm up uses gas that we don't often consider. Or sitting waiting somewhere with it running, when we'd shut down if it were warmer. (Like me, sitting at the bus stop everyday)....... :(
