I have a 2008 JKU Automatic with 70,000 miles on it and it seems to be dropping MPG's faster than a drunk girl in stilettos.:doh:
Here are some fun facts that should answer the majority of your basic questions. All my fluids are up to date and have always been changed at the scheduled intervals. Like most other 3.8L's, it burns oil like a mother trucker, approximately 1qt per 1k. Unsurprisingly, when I mounted my 33x12.50x18 Mud Grapplers and RR XHD bumpers I lost a couple MPG's. Conversely, when I ditched the hardtop and installed the Trektop NX I gained about 1 MPG. I am getting no idiot lights and the engine runs and sounds the same as it always has.
Over the past year, and after all the aforementioned modifications were installed, I began watching my MPG's drop at a pretty consistent rate. I began 2013 with my dash panel display showing approximately 13-14 MPG's, depending on driving conditions, and will be ending the year at 10.5 MPG's!
Is this common for a 6 year old 3.8L with seemingly no other issues?
I am stumped.:thinking:
