[Tanga]

Full to Empty 377km on 98

Just filled to the brim, $123 of 98 Octane

That's shocking. Was it round town driving?

Yea bro, to and from work, bitta boosting, bitta slow driving

[Bender]

I done just under 380kms to a tank, Over half of my driving is on a country road, Been trying to driving nicely and staying off boost as much I can with having it good boot now and then.

$112 to full just over 52 liters of 95 octane

[SEAN-NZ]

i got 8.9k to the litre, with 80% of that coming back from auckland, although i might, or might not have been speeding almost the entire way back

[Badger_01]

Still better than me, I'm getting less than 300km a tank on 95, fully up every 2nd week lol

[WOODY72]

Last fill up 50.1lit to 190miles = 17.236mpg

300 to a tank! f**k me! are you towing a huge boat around everywhere you go?

I only get that kind of shocking fuel economy when I was giving it alot a right foot.

usually get between 400 and 450km to a tank with around town driving, bit of motorway stuff occasionally. and that was after I put my cams in which im sure didnt help economy

I noticed my fuel economy went up when i stopped downshifting on the autobox.

[ako]

Jeeeesus thats some horrific gas use - like "is something not working right" type shocking

Are you driving it solely foot-flat or from cold starts and thats it?

I remember one of my 7G's did similar when the 02 sensor died a death by avgas

[97vr4]

I get 420km per 55L of fuel
Gas light comes on with 15L in tank lol
If i get into boost and play with the car a bit i get about 340km to 55L
I also run 16ish psi
$78 for 55L of Sunoco 94

Are you running a VTA BOV?

I get pretty good economy, in my experience the following is a good path to follow.

The things I would check
1) Driving style. Don't let the intake pressure get out of the -21inHg -10inHg range (requires accelerating VERY slowly) and see how you go. If you get 550+ out of a tank, its not really worth persuing the rest of the list
2) O2 sensor
3) Boost leak test
4) Make sure you are not getting excessive knock (i.e. running 14+ psi on standard intercooler will put you on low octane maps)
5) Get injectors cleaned (or new ones, I got ID1000s)
6) Get a tune

You forgot one important thing between 1 and 2 check your spark plugs are good. These make a HUGE difference to economy.

Yeah I have no idea, fuel economy is better since I replaced the fuel filter hahahaha

Are you running a VTA BOV?

Nope its a recirc one, looks like a knock off GFB one.

I need new plugs but I cant find anywhere that sells BKR7IEX, was going to replace the O2 sensor when I get an AFR gauge and sensor. Def need a tune/remap but pretty sure theres no one up here that could do it, still have a few things to put on the car like fpr, large bore fuel rail adaptor, walbro fuel pump, ebc

[Kenneth]

Yeah, thats true. And also running high boost with standard ones probably won't help keep detonation at bay.

STA Parts in Auckland sell them - they're about $20 a piece plus shipping. Super Cheap may also sell them for less.

STA don't have any in stock and whenever I ask them when they are going to get them in stock they give me the run around and go on about the ones gapped to 1.1mm. Three times that has happened, so f**k them lol

[wintertidenz]

PM me - if you can't get any down the line then I could get some and courier them down.
