MPG updates

Ok Ill do 89 then for a few and see what happens. Still doesnt explain the sudden drop but oh well. No codes, no lights no problem.. I hope!

My memory is escaping me.... how many miles are on it and do you know when the plugs were last change? I noticed a stark decrease in mpg as I approached 30k on my plugs.

Maybe disconnected the battery for the hell of it too.

Ive got 79k and only 2500 miles on the plugs, just did complete 60k service-all fluids plugs front diff bushings belts- when I purchased. I will disconnect the battery to see how that helps...

I disconnected the battery for a min to reset the computer, I will update to see if that does anything...

I hit 17-18 MPG coming this last weekend 6 people plus luggage and both front and rear AC on I did however have my basket and cross bars off. Running no tune just corrected for tire size and on 87 octane.

Literally a minute? Needs like 10-15 for memory to reset (I turn the key on for good measure too)

[06JeepXKHEMI]

Not literally a minute, everything was set back to 0, mpg, time running, etc.. Ill go to it for longer but everything seems to be cleared

[Matt]

Lol got it

I have been running 87 since I've had my XK so maybe I will try 89 next fill up? The only mods I've done to the engine so far is put the K&N drop in air filter which I feel improved but then the tires and lift went o,n and I am down to an average of 12-12.3 city driving mostly.
