33.7L/100Kms? Everyday Driving

[PTR_NITRO_FG]

Type of driving too....

Coming from mixed freeway/city driving....I was getting 11.8L on the computer

Now I've moved closer to work....was very shocked cause now at 14.8L

Stock car.....have been 'thrashing' same as usual....the kms from cruising really help bring the average down.

Maybe Don does lots of freeway/cruise stuffs?

^^ exactly what Pete said

Mix of freeway/country town driving with the 'occasional' flogging - coz fun

(with 98), it's simple, if you're cruising at 100km/h+ on relatively flat ground, any tuned car should be around 10L/100km (plus or minus a little, depending on mods/setup). If you're driving in situations where you're "wasting" more fuel, you'd can expect anything from 13L/100km to 25L/100km, but the range depends on how much you're thrashing it.

30+L/100km is only E85 at the racetrack sorts of averages.

Good to see that you figured it out If you drive quite a few tanks with your "normal routine", you'll soon track down what is specifically causing the spikes or troughs in your fuel usage

Its still using too much and the average is creeping back up (currently 24.8l/100km) I spoke to the tune shop , theyve said it could be aftermarket fuel rail leaking , checked it no leak , no leaks anywhere but stink like fuel when idling (like its running rich) but ive been told its not .

tuner suggested getting it to 100km, setting cruise control then flicking to instant fuel consumption on the trip. would this be an accurate way of checking before I take it back ? By the sounds of it theyre going to charge me to look it over saying it cant be the tune . my issue is the previous tune was running more psi and yet chewed half as much as it does since the new tune.

they took out my seimens 80lb deka and put in the id1000s, cleaned my fuel system and put new inline filter and replaced a slightly crushed steel elbow. so im thinking if its the fuel rail itll be when it was reinstalled after the new injectors. I just dont get how it can consume more now running less power with "better injectors" im starting to despise the car :S Not feeling like its the pride and joy I once thought. I dont even wanna put anymore money into it, getting ready to possibly sell it

new tuna

Exactly... If you can smell fuel and there is no leak, tell the existing tuner to diagnose it for free (the fix may not be free, depending on the diagnosis) or get a new tuner if they won't.

I always start the car and let it idle to warm , then drive (usual operating temp in my other ute was about middway) but with this car it just above the first line (like a quarter or a little more) that's the general temp I see other at with similar mods as well. my trips vary but I would rarely drive under 25 kms per trip

Trips are long enough to get into operating temp. Where your temp sits would suggest you have a cooler thermostat. The tune should have been adjusted accordingly though. That temp would be within the warmup cycle on a stock tune for example, which means running rich. Give it time like you say to average out before taking it back

Could just throw a new std thermostat in for sh*ts and giggles? Yours could be crook even? I could be full of sh*t?

Come over, lets pull the tune and see what has been done. It is usually hard to determine fuel economy by numbers however based on what you have said it does seem to be using too much. The engine should operate on closed loop control so it should deliver OK economy regardless. However they could have butched things that kill economy.

Is it still stalling?. I assume you are using bp98

For the record, my ute drinks like a sailor come in to port on cold start but after 2 minutes a it settles down. You're driving a reasonable distance to your mates place?

(Still think you should get some tuna in you)

Dont really want to have to change tuner, and as I said hes ruptable .. ive used this place in the past and not had drama... I just dont wanna pay again for a job that's already been done.

Theres no more stalling issues anymore, when they swapped the injectors they found orange rubber everywhere .. turned out someone had put in some kind of additive or e85 and it competely ate the fuel filter and sent rubber bits through the whole system, so injectors were changed and upgraded from teh siemens deka 80lb to ID1000s and the fuel lines were all flushed and the filter replaced
