I know this is a silly question but have you switched to ethanol or buying your fuel at an independent servo?

Calculate your mileage manually from the km traveled and fuel filled. More accurate than the computer readout.

Mine reads ~1L/100km low, and the Aeroforce gauges that are plugged into the same data through the OBD2 port, read ~2 high.

Are you really using more, or is it just telling you that you are?

Good question but no, haven't changed where I get fuel from.

Yeah definitely using more.
Tested in manually several times.

My wife uses 2-3L/100k more than I do with the way she drives, regardless of fuel/terrain/weather. If you're the only driver, is there anything significant about the way the Jeep drives now that it didn't do before?

Did they change the oil when they did the warranty repairs? A different oil grade would more likely change what was coming out of the tailpipe before it changed fuel economy.

Did they remove a bash plate that hasn't gone back on?

So many questions

LOL She actually does use more fuel.

But I have taken that into account and I have been driving solely my self to test it out.

No bash plate removal but there could of been an oil change to cause that only thing is that oil was on there for a 2000kms before it started doing it
