Jtphoto i think thats 1 factor. Philippinea have only 95-97-100 octane we dont even have 93 octane here
But i think jeep philippines would tune this to whats on available octane in the market available? Buy yes i ordered flashpaq, k&n drop in, jet chip throttle body spacer.
Thinking maybe i can raise to 14-15mpg i would be most happy jeeper here ever hahha

 

Yeah mine's OK for lifted with 33's and winch/steel bumper. The dash monitor actually says it was 15.5 L/100 km but usually it is optimistic.

Do you stop and go a lot in traffic like a previous poster said? That really hurts the consumption also.

 

3" exhaust will not gain u tq but will gain upper rpm hp. Way to big of exhaust for the hp that 3.8 is putting out unless you Ripp charge it

 

Nope pg i live in a province in philippines not ao traffic here... Beleive me if i stop go or start up throttle saying to me 34-36L/100km
Thats why im tired with my jeep. The 25L/100km was rolling for few seconds already........ I really dont know what to do
Unless the jeep philippines short the gears and my stocks gears isnt 4.10? What you think?
I tried jacking rear tire turn 1 on tire give me 2 turns in drive shaft
So i didnt know i need 2 turns for tire? So it should give me 4 turns in driveshaft? Or only 1 turn for tire is enough?
Thats why i wanted to order gears for me but alot people telling me stock rubicon with 32 should go 13-15L/100km or 15-16mpg why should regear

 

Tooadvanced
After the stock maniforl or headers they call i took out the filter of the catalytic only left and right but i stayed with the catalytic with out internals then i took out the 2nd catalytic or thats a primary muff? Then put there 2in pipe until the y pipe i put a new primary just to silencer the big noise then after y pipe thats the time i made 3inches till to the end i put smaller thru and thru muffler at the end
When i installed everything i notice i gained a small torque
So now i need to repipe to gain more torque? Thus this config affect
My 10mpg? Or no and just i can top end? Is this 1 factor ill return the stock pipes

 

How about big like 8-10mm spark plug wires? Maybe it will help? Were can i get those?
Trying to find on ebay cant find any?

 

Your running pretty much a stock diameter tire so I would think that shouldnt be the cause. Are you sure your catalytic converters arent plugged? Im getting 12mpg on my Jeep but Im running 37s.

 

Don't waste money on wires. OEM are the best. The jeep's ignition system is already very optimized. Check your PCV valve, check to make sure your brakes are not dragging etc.

 

Do you keep resetting the mpg display? Just leave it alone and drive, and calculate your mileage by hand using the fuel you use and the distance travelled. You pretty well have stock diameter so your speedo should be very close. Do that and tell us what your mpg is.

 

always be prepared just empty every pocket sir
