Petrol Consumption R33 GtsT

[Richo]

Just out of curiosity, is 380 kms with a tank(60Litres), bad?

mixed city and highway (decent) driving, no major mods.

Could it be better? if so.. how? and don't say, don't drive a skyline

That is almost 16L/100Kms for a 2.6L car

Im just not very happy with it, and wanted to see if you guys out there are in the same situation.

Cheers.

I would usually get around 400 - 450 kms from a tank. it's all in the tuning really. Is your car stock? What mods does it have?

[JAS-25T]

you say your talking about an r33 gtst with no major mods.

so how is it a 2.6L????

anyways, i get around 450l per tank, which i am pretty happy with, i end up with a 11L/100Km's average, but thats when i drive around changing before 2500rpm.

i do also give it a hit at least once each time i drive the car.

LOL same! i love to give it a quick stab

[hanyou]

mine is liek 350kms a tank.. with the occasional jabbing of the pedal haha.. gear change around 3500rpm...

[skye]

I’d usually get round 400-420k's with some occasional 'spirited' driving..... hmmmm

Hmmm...I was just about to put up a similar post Ricoh

I've been battling the whole fuel consumption thing for a while...like most of us. My set up is relatively mild: 3" front/dump, 3" HF Cat, 3" Kakimoto at the tail, Trust Pod.

Last weekend, I put in a new O2 sensor which seems to have helped a bit (There are many threads about this by the way). I was getting 350Ks max from a tank (Running on/off boost...it didn't matter) but so far I have got about 120kms from 1/4 tank (BP Ultimate)...do the math...hoping for 480ks a tank. This is an obvious improvement so I recommend fitting a new one (O2 sensors only last 40000Ks, when they go kaputt, the ECU runs rich by default). I fitted an EL Falcon O2 sensor which cost me $86 from Motor Traders (A hell of a lot cheaper than the $180 Nissan Genuine part). The only catch is that you will have to cut and re-wire it to fit the Nissan connection...No big deal, the colour of the wires are identical. I can give pics if you want them.

I also cleaned the AFM with some contact cleaner that you can buy from Dick Smith. I am using a Trust Airinx pod but I need to partition it to eliminate some of the hot air. This should help the efficiency a bit as well. NGK Platinums are also a good investment.

Always remember the obvious: Tire pressures/alignment, oil viscocities (Not kidding), fuel filter, type of fuel, injector cleaner.

At the moment, things are looking promising, even if I squirt her a little just to make my presence heard

By the way, I would never tell you to "Not drive a Skyline" I would rather pay an extra $20 a week on fuel than drive a tryhard OZ performance POS

Remember, she's quite a heavy, well built car so heavy fuel consumption is a trade off. Luckily we don't have to rev the Sky's tits of to get some performance out of them...it would be even worse then.

Did I say NGK Platinums? I meant Irridiums...sorry had a moment

Pics would be good mate!, Ill give that a go and see if it works for me. Thanks

Here you go.

If you want help in locating the O2 sensor and fitting I am happy to advise. I have refrained from doing so at this stage as I don't know your knowledge level and I don't want to offend.

I had a once off distance of 650km to a tank.

I was driving on the space saver spare wheel for half of it (had a flat in sydney, drove to newcastle and back on it before I could get the tyre repaired).

So half was normal commuting, the other half was freeway driving at 80-90kph.

[Richo]

Cheers Terry M. and btw you wouldn't offend me by giving me more info since my knowledge level when it comes to all of this is very limited.....to say the least

Now, I have another issue that I havent even noticed before.... every week regardless of how much petrol a have left in the tank I fill it up again...now, the first 200 k's ,the petrol gauge doesn't move at all, then it starts moving down slowly past the full tank line and then...you can almost see it go down as you drive, it almost goes down 3 1/4 of a tank in 80 to 100 k's. weird. anyone with the same problem.? or anyone know why this could be happening?

Thanks guys!!

[terry.m]

I have the same problem, the guage is all over the shop after 60Ks from filling up. I wouldn't be too concerned. I resist the temptation to look at the guage until I get home and I'm on my level driveway, then I get an accurate reading.

It seems to vary heaps depending on road level...stupid pedantic thing.

If I can help with anything mate, feel free to PM me...I've been around Sky's for a while now

[jared parker]

on the first full tank in my 33 i got 150 ks yeah i gave it a testing but also got 500 on a full tank but that was just highway driving

[mitchy_]

i get ~320-350 off of 60L, but mine runs quite rich... might try that O2 sensor fix, see if that helps.
