Fuel Consumption

Post by **Palacian** » Thu Oct 07, 2004 8:38 am

Does anybody have any modification ideas to better my fuel economy to my standard TJ ? I do quite a bit of travelling for work and was hoping there is a solution to getting some better fuel economy out of my rig. (other than getting a lighter foot)

Also any ideas on increasing power/responsiveness without comprising fuel comsumption (I want my cake and eat too! :lol:

)

Throttle Body Spacer and a bored throttle body.
wont help with fuel economy.. but if your in a stock TJ you would be getting better than me.its a jeep thing.. you'll learn to understand.

Face it, it's a big mother of an engine so you are not gonna get fuel economy at all - just fuel usage

bigger tyres, less revs at highway speeds.it will take power though and wont be any better in the city.

Because they already rev so low, it will get worse with bigger tyres unless you do your ratios.

Try a K'and N air filter. and cat back exhaust.

Sorry to be the bearer of bad news but it's a Wrangler thing... expect even worse economy with the roof off!

Don't drive faster than 80km/h

Yeah what he said and make sure it's always downhill and try not to use the engine! An aftermarket hole cut in the floor which allows your feet through to push often increases economy. :twisted:

Just for interest, what is the fuel usage for 100km's on the highway.

I can manage 13.5L/100klm on a good day

33's, 4.56 ratio, 4" lift, 5 speed manual
17l/100km in town and on the hwy

thanks guys....

The lift and the tyres make a big difference don't they.....

13 not bad but 17 ouch...... still wouldnt mind getting one though,,

yeah once you hit 33's it's bye bye economy

Post by **YankeeDave** » Wed Mar 12, 2008 4:39 pm

yes 33's + high mount winch + front bar + rear bar + tyre carrier + sliders + suspension lift = worse economy,

keep it light and low and you'll be around 14l/100km even with 32's
