2002 short box rebuild questions
Hi, the liberty I bought with 56000Km ended up having piston slap and under warranty the dealer replaced the entire short box. Before the rebuild I was getting approximately 100km on 16L in the city, but since the rebuild it has nosedived to 21L. I know that fuel economy usually is bad following a rebuild until the engine gets worn in but i have since put on 5000 km.
Does anyone have any advice for me? I know jeeps aren't great on fuel, but I really think this is outside the normal limits. Also, I have to drive very carefully to squeeze that fuel economy out - no speedy accelerations, speeding, etc.
At first i thought it could be tires - I do have an aggressive BFGoodrich all terrain tire on. Do tires make that much difference, most people say no. Besides, same tires before the rebuild and resulting decrease in fuel economy. HELP, PLEASE!
