Thanks for the info guys. Sneaky how many km you getting out of a tank in the xt? Do you do city driving? I used to get around 450km out of the xr5 city driving.



I don't run my tank to empty, not a good idea to do that but I average 11.5l/100 going by km's driven vs litres filled, that is the only true way to work it out, and that is all city driving, but it is mainly work commute, so I'm not ragging the car but I am in solid bumper to bumper everyday. Basic math would say i could get about 520km our of 60L tank but I don't even think you could fill 60L, I'm sure the XT would stop before I've used 60L of fuel, maybe some of the other guys would know exactly how many litres from bone empty you can fill the tank with. Comparing with your XR5, from my experience, all things being equal, 400km or thereabouts out of a tank with the XT is my guess

Due to the shape of the fuel tank in the SG you'd struggle to get any more than 55L out of them. I'd not want to run that low in general use anyhow, only when switching over fuels (98 <-> E85)

I get 400km to 48L = 12L/100 on 98, with all city driving. I would get 420km/48L =11.43L/100 when my car was stock.

The weird thing about the Forester fuel gauge, at least in my case is between 3/4 to 1/4 marks it reads that I get about 100km traveled between those marks, it's kind of a sinking feeling, 200km out of the 1st 1/4 of a tank is good times, but after that, a rather rapid descent towards E and thinking about petrol stations again, so it reads something like this:

F - > 3/4 = approx 200km
3/4 -> 1/4 = approx 100km
1/4 -> E = approx 150km

so for me it's kind of hopeless. :cry:

Thanks heaps for the info fellas. Looks like it would be comparable to the xr5 fuel consumption wise then. Are the older GT's better on fuel being a 2.0L as opposed to the 2.5L?

just restarting this convo 2 years after the last post.

xt with a 2.0 6-speed here.

i too am getting an average of 300km to the fuel warning. going by the gauge (i know it's not accurate):
- full to first indicator - approx 60km (have touched 75-80km if i granny shift and keep it under 3000rpm)
- halfway mark - average 150km (have gotten approx 180km if granny shifting etc)
- fuel warning - average 270-300 (max distance has been around 340-350km)

a mech who changed out the spark plugs during my last service has said that the car is running a little lean due to the discolouration. have cleaned out the MAF too and noticed smoother acceleration. will look into a new o2 sensor at next service.

now...this new to me foz is tuned for 97 and managed by ecutek software (?). power is somewhere in the region of 310hp according to a dyno sheet that's 2 yrs old that was passed to me when i bought the car.

now...if i attempt the ecu reset procedure as mentioned earlier...will that screw anything up? or is that only recommended on a non flashed ecu?

thanks for any input.
