Hi i recently got my Ps and started driving my 92 R32 GTS25 by myself and i have filled up twice now and i think im getting really bad fuel economy. Im a pertty big noob when it comes to cars so i couldnt really tell u wat mods i got. Both times i did around 320 km per full 60L tank and i asked a few ppl and their gtrs do better then that so im just wondering if there is anything wrong and if your guys got any suggestions thx

Such a large factor with fuel ecconomy is dependant on how the individual drives the vehicle...

e.g. Car: R32 GTS-t

Mods: Lots...

Good week at work, 400kms easily...

Sh*t week at work - girlfriend - momentary fits of rage, 253kms (and own PB)

It really does depend mate... also, mods? Any? It's an RB25, and you might have your lead shoes on...

But around the 330 - 400 mark I think you'll find is pretty stock standard.

Cheers. :unsure:

Do a major service on your car, something sounds wrong on yoursl ...my r32 na does way better than that on a full tank like 400-500+kms., with the occasional flooring it lol.....

some advise, watch your fuel guage when driving normaly, then watch it when you floor it a few times the fuel guage shows how much you really use when doing that.

auto rb25t with 190rwkws and i get 370 to 450 from 60l champ

thats 15L/100km ! thats hardly good either..

acidkid: if yours is auto that could explain a lot.. seems like economy on the autos is quite a bit worse than the manual.

I get something like 130 - 140 klms per 15 litres for my manual r33 - Though just today i got 120 in about 20 ltrs ( but thats cos I had a full tank, and i was demonstrating the turbo for a couple of my friends).

who cares about fuel economy, you drive a skyline not a toyota echo,

if i want fuel economy i wouldnt be driving a skyline,

enjoy it while petrol is still affordable, theres less and less oil in the world, in 10 years time we'll prob be paying $2- $3 a litre

yeah. at the start of each tank i've been known to say many a time "okay, no hooning it for the whole tank to see how many Ks you can get" ... well, that plan always goes out the window.

i get a bit over 300km to the tank most of the time. i should change these o2 sensors like everyone says! i have trained myself to always just put it in neutral down hills and rolling toward the lights though.

my car is r34 gt4

i got 21 litre per 100 km

i think it's very bad

i already check once by maintenance man. they check exhaust emission. and said no any problem...

i want to know: how to check o2 sensor? and can inject oil to tank fix problem?

i bought this car form japan, nobody driver it in nearly half year, is this reason for fuel problem?

if your car was turbo i would say that u should be able to get more but NA you should definately be getting more, probably should be closer to 450. Definately get it checked out by an EFI diagnostic center.

If you put it in neutral that would use more fuel according to my understanding.

When you put it in neutral the motor has to dump fuel in to stop the car from stalling. If you are rolling down a hill or rolling towards the lights in gear you are using less fuel because your motor is turning itself from the momentum of your wheels. I think most ECUs cut fuel on deacceleration.

Someone correct me if I'm wrong.

    • How dare you sell your unreliable Skyline and buy a reliable, Toyota/Yamaha car with a strong gearbox, torsen LSD and Toyota reliability. At least you won't need to worry about oil pumps, big catch can, oil restrictors, blowing off power steering belts, sheering off 3rd gear, failing ABS relays/pumps, etc.
    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.
