Hmmm sounds high...

I’m on 35s, 488s, roof rack, front rear bars, winch blah blah blah and i end up around the 15 mark, 13 on a good day, 17 on a bad..

Couple things i learned, check all pipes going to intake as one could be split particular the evap purge line and brake booster lines... if they are split i noticed my temp and my fuel go through the roof...

Cleaning the throttle body helps too, and I also chuck in a total system cleaner once a month.. I may also be silly but I find that only using premium fuel rather than e10 gets me further and the engine runs smoother..

Replace your fuel filter, clean you injectors and clean you MAF sensor. YOu should be getting 11-12 LPH, thats what I got when mine was stock.

YOu can also check all of the wheel bearings and wheel alignment, it all adds up.

Good luck with the hunt.

Fuel filter, on the 3.6? Am I missing something?? Where is this filter, or are you talking about the pump?

Fuel filter is part of the pump.

So good news replaced air filter, cleaned mag sensor and oxygen sensor. Did a drive to port Stephens from Sydney and the car is sitting on 11.3 so seems to have fixed the poor mileage. Will see how I go back in city driving when I get back

I didn’t realise this was a serviceable filter.... thought it was total replacement... I know the 2.8 has a filter...

Anyone have a part number for the filter only or quick link on who has them?

@jeep’ers fuel filter on JK petrol is part of fuel pump, one at the bottom of pump and one inside housing. You replace pump when you change

So my post about being a complete replacement part was correct then...
