I use BP Ultimate, when i get down to just above a quarter i have about 270 on the clock and this is while driving normal, no thrashing. I got the car tuned about 6 months back and everything was fine, i was getting this same KM amount even before i got the car tuned. I don't really want to let the fuel get to almost empty, so i'm thinking i would get around the 350 mark if i almost let it go to empty.

Could it be my 02 sensor or AFM?, or do the KM sound ok?

thanks

the mods i have are:

PFC

FMIC

3" Turbo exhaust

11 pounds

Pod CAI

also got some irridium spark plugs put in

^^^ that is the big thing. there is no point saying 3/4 of a tank, as to 1 person it may be 30L, to another it may be 40L.

work it out as L/100k's. so if you get 270k to 40L then you divide 40 by 2.7, which gives you 14.8L/100ks.

also if you have a pfc then it should be due to the tune, not anything else if it hasn't changed after the tune.

also it depends on what you class as normal driving. if you class it as changing gears at 4000rpm after using 90% throttle to get to 4000rpm, then you will get different economy to someone who may rev to 5000rpm but only use 40% throttle.

I too get crap fuel economy from my R34 GT-t, around 300-350 max around the city. Doesn't seem to make much difference if I drive like a granny. I'm thinking of changing my O2 sensor as I'm putting in a new dump pipe next week anyway.

What is the general consensus on O2 sensors to suit this? I know several people have been using the Falcon I6 ones successfully. Should I get one of these? Whats the part number?

Thanks!

What you can do is fill your tank, record how many kilometers you have gone before you fill up again (use the odometer thing) I usually use 60 or 100km and take note of how many litres it takes to fill the tank at that 60 or 100km mark. So say 100km ended up taking 19L, then divide the size of your tank by the 19L, and then take that number and mulyiply it by 100 and you will get a number that is near the amount of kilometers you would get to a tank. sorry if any of that is worded wierd, it's 3am where I am.
