I have an R-34 GTT and it does about 20MPG.

I am told this is as good as it gets.

You don't seem to be too far off that.

 

I get around 180-220 miles from a full tank so your figures seem about right werent expecting that i take it

ditto

 

i know what you mean.. i knew they eat petrol but jeasus!!! i have also done around 150 miles in 3/4 of a tank.. Think i will buy shares in Tesco Fuel..

 

thats about spot on,mine does that and always has.

Sadly, i can say the about the same...

 

Every few months I do a check, and filled up to the brim (£57 later!) that was 3 weeks ago

Got exactly 240 miles.

Thats £1 every 4.2 miles!

The way I look at it is like this. You chuck £1 in for Out Run, or your latest arcade game, and get 3 mins of fun. For £1 we get 4 miles of REAL fun!

Makes me feel better every time I fill up

 

Could be the O2 Sensor. I have read about faulty ones causing large fuel consumption.

 

i think 20mpg is brill only used to get 6mpg out of my buick

 

i just got 252km out of 3/4 of a tank.........i fill the beast up about 3 times a week

so then I shouldn't be concerned about this huh?

 

again i'll be another one that will agree that's just about right .... obviously depends how you drive too ..... some times it can be less and on a hot day even worse still .... oh and don't rant on a hot day

 

had a bit of a run last Saturday,averaged about 22mpg,which i was quite pleased with
:cheers:

 

dont forget, you get more fuel per £ when it's cold!

 

heh heh heh, well my auto has hit 30 mpg, but that was a very long and slow drive.. she averages about 27mpg

 

Normally, it takes about a week (normal driving) for a quarter tank. Learning from this forum that the Exhaust Gas Sensor can be a culprit to a lot of things, I bought a new one. Three weeks ago, I installed a new sensor. Sure enough, the mileage significantly went up. Now, it takes about a week and a half for a quarter tank (again, normal driving).

I bought the Three Wire Universal Lambda Sensor (1 Black, 2 Whites, Part Number - 86300, Price - £21.60). It comes with a simple instruction.

I also bought a 22mm Lambda Sensor Wrench. Without this tool, you'll have a hard time or may damage the sensor during removal or installation (Part # -FTA901, Price - £6.45). Here's the site:

Hmmm, ok. thanks for that peeps. Not quite the answer I was hoping for, obviously, I was hoping for "Oh, you just need to adjust the wotsit by three quarters of a turn & you'll get 30mpg", but it's at least comforting to know mine's not abnormal. I'll probably get it checked out sometime anyways, just to be on the safe side, but I guess if it wasn't running right it would fail the emissions test? Is the black sooty mark on the wall normal too?

cheers,

the black sooty mark will be burnt fuel ... skylines naturally over fuel ... hence sometimes flames out of the exhaust .. this can be a good thing as theorectically you could raise boost to compensate (in my opinion) and you don't get detination

over fueling not a problem (bad on fuel i guess) but under fueling is really bad

i could be completely wrong but that's what i think i know ...

 

To be honest GTS-T an GTR are not that much differant on fuel usage and yours is normal as is the black sooty back end of the bumper near the exhaust .Dont worry about it .Try taking the car on a longish trip and hardly hitting boost and never go above 65 mph you will be amazed at the differance on the fuel consumption ,floor it the trip back in every gear and the fuel usage will be twice as much and you can nearly see the needle going down

 

has anyone noticed that their fuel gauge goes down almost as fast as when at speed ... when in traffic ... not overly happy about that as i'm having to drive to work till my arm is fixed

 

I get about 17 - 20 mpg from my R34GTT around town so your figures are about right, you should be using Optimax though, it's 98 octane and better quality, not supermarket stuff.

yes i have noticed that on almost every heel-toe downshift you can hear the car spitting fire nothing comes out the muffler as of yet though since I haven't had a chance to get my downpipe and de-cat pipe fitted onto the car.....can't wait till i do though

back on topic....once I get my exhaust finished and my new SMIC and MBC on the car I'm going to have an SAFCII installed and dyno tuned....i'm hoping to be able to smooth out the a/f ratios at idle so as not to consume AS much fuel when i'm just sitting still.......i swear sometimes I can actually SEE my fuel gauge drop when i'm in traffic :funny:

Exactly right matey. Under fuelling is bad anyway but on turbo charged motors it's critical this doesn't happen. Overfuelling slightly won't cause too much damage but you might build up carbon deposits on your valves etc, a little more quicker than normal.

 

i get between 270 - 300 miles per full tank, but mines mostly school runs, and not all out... the occasional squirt tho... these cars CAN be reasonably good on fuel, if you want them to be..

also mines mapped to be lean at low throttle, which also helps, and is where most of my driving is done..

p.s. my cars 340 ath with quite a few mods...

 

thanks for all your info guys, I appreciate it.

 

fuel consumption

I only put $20 in at a time,, the more fuel you carry, the more fuel you need to carry it,,,
Over here I have a saying that goes with the territory,, If you drive a V8, then you don't give a F@#^ about fuel economy,, kinda the same for the Skyline I guess,, I didn't buy it to be a daily driver,, It's a toy and I intend to play !!!! lol
