Skyline Fuel Consumption


Recommended Posts

I get about 350km per tank and thats with putting 55L in.

I drive alot of highway and im rarely on boost....

:

Think its time to change o2 sensor...

What else you guys think should be changed...

I used the Nulon fuel system cleaner and that got me from 310km to 350km per tank...

that was a once off and the fuel economy is the same.

Can the fuel filter cause a problem?

The car is making 215rwkw with afrs of 11.4.

if the fuel filter is making any sort of problem, the only thing it could do is get blocked really, i dont think it could flow more than it should. with your afr at around 11.....it shouldnt be using too much fuel. Ive heard o2 sensors need to be changed every 75 thousand kays.

same, i have cooler, full exhaust, pod and atmo venting BOV.

try puttin ure stock bov, or a plumb back one on. will help your fuel ecconomy shitloads. atmos throw your air fuel ratio out.

I have a r32 gtst fully stock and i get about 420km out of 52litres. But thats with alot of thrashing and driving in peak hour traffic. Mrs on the other hand has done 460 km out of 50 litres. So yes depends on how you drive it and sort of condition you drive in.

My skyline used to give me around 350-400 kms from a full tank with little thrashing and mostly freeway driving.

But I got it checked and found that the crank angle sensor has a little gear which was worn out and because of this incorrect information about the position of the pistons was sent to the ECU. But when i got that fixed now I can get 450+ from a full tank with some thrashing. So roughly 10.5-11 litres per 100km.

Love it.

So if you are getting a shit mileage from your R33 I would have it checked.

LOL!!! That makes me feel better!!! I get about 22litres/per 100km, around town with the occasional burst. So thats about 300KM on a 70 litre tank. 4.5km/per litre.

I didnt buy a 400kw GTR to drive a fuel efficient car, im doing my bit for Saudi Arabia's economy, more crude oil, burn burn burn!!! :D

shiet! thought i read that wrong initially. that's just insane hehe. Bet it's fun though.

seems like you guys are getting pretty good figures.

my ca18de - 10.5L/100km

my rb20det - 10.5-11L/100km

hopefully my next car with an rb25det should be within that range.

Ok prior to filling up full tank last night I had:

400 KMs on the odometer and just a tad under one quarter of petrol left... so in theory I could of added an extra 30-50 KMs easy... taking it to a total of 450 KMs... mind you this is pushing the car every now and then, boosting it quiet often!

I am now certain if I baby it then I could esily get 500+ out of my tank... and my car is R33 GTS-T S2... pod and atmo bov.

How the hell do you get that good economy? I think i get about 400kms or so if i run it dry (done it)... i make a habbit of filling it up after 350kms now. Although that does tend to only take 50litres.. I dont trust me fuel gauge, its an outright bloody liar hence why i always fill up at 350!

My car is in good nic and only 46,000 KMs... I warm her up before boosting every time... its also auto so should drink more than manual... try and see if u can just run her dry or at least have the needly touch the last bar... the light should come on soon after and ull have about 10 litres. Or carry some petrol with u at the time...

BTW my car has done 440 KMs and the needle is barely touching the last bar... so I should be right for another 20-40 KMs...

This weekend I drove to Evens Head (south of Byron Bay and Balina). I went via Springbrook (which adds about 60km of steep curvy slow mountain roads) and I drove pretty slowly for ages looking for dodgy camping sites, with the odd bit of sideways rally driving. I got 10.1L/100km over the 500km trip. Car is a R31 which has an auto 2JZGTE in it

Hmm seems my fuel economy is pretty spot on then. Been giving the car abit here and there (more then usual) and I usually hit 350-400kms right before the Empty light comes on - about 50L to fill up full tank.

Just hit 400kms this week with less enthusiastic driving and E light hasn't come on yet, should be soon though. So I'm game enough to say I'll be able to get 500kms out of 50L if I drive completely off boost for most of the tank, and definately over 500kms if I use up the remaining 15L. :D

Also, I believe tank capacity of the R34 is 65L, does that mean 15L is used for the reserve?

I wouldnt advise running the car dry as it will clog up the engine with all kinds of shit from the tank...

I hear people say this. Please explain? The pump always sucks from the bottom of the tank so any dirt would get sucked up regardless of the fuel level.

Read the manual... also my family friend mechanic told me not to run on empty...but i would like someone give an explonation for this...

Huh? Are you literally talking about driving until you car stops moving due to it having no fuel at all? Who in their right mind would want to do that anyway.... I don't have to read the manual to know that my car will stop moving if I run out of fuel. If I get to the bowser before the fuel runs right out, no more crap will get sucked into the engine than if it had a full tank.

No in the manual it says to fill up the car prior to it coming even close to going dry... usually i think a quarter of fuel is a god indication to fill up.

Anyway we going in circles, fill up prior the light coming up...

    • So, first things first, it's had a service for all fluids (2x coolant as it has air/water heat exchangers instead of air/air), new air filters (they were terrible, and one was pinched when installed by NIssan's "technician"). Also, both the boot and bonnet gas struts were shot, so ebay sorted some new ones, the jack handle kept me alive for the first service It needs tyres (more to come on that...) and the brakes are horribly grabby, looks like they've been badly glazed sitting around in Sydney traffic. On the bright side there are no obvious leaks and it runs well. The car goes well with 300kw (stock, claimed, I'll put it on a dyno soon), does good skids and handles reasonably well eg in long medium g corners. It is no cruiser like the Fuga though and is noticeably jiggly on the average (poor) rural road and terrible on corrugated dirt.  I'll get some road/race shocks in it shortly which should help.
    • So, for those following along at home, I've had the R32 up on stands for a while since a minor incident in the last rally, which required a new rear quarter panel to be welded in after the car had been (pretty much) put back square again. The problem is of course, that some R32 GTR stuff is simply not available (eg front guards) and other things are either expensive (second hand) or very expensive (nismo heritage).   In the end I've decided to try out a v37 with some track days, hill climbs etc before going ahead with modifying it for race/rally like the old GTR. To do so I've picked up an ADM Infiniti Q50 Red Sport, rather than a JDM car which offers much better value but might lead to complexities when I discuss spec with the production racing guys. In the meantime it will be my daily (well, more like weekly) driver, mostly highway use to Canberra or Sydney. BTW yes, I did notice it is auto-only, and yes I did know the Z comes with the same motor in manual. Big issue with the Z for me is that it is unlikely I can meet the new rally cage clearance requirements in that chassis so I've gone the 4 door/auto route The colour isn't great for rural lyf, and neither is having a sunroof for racing, but the Q50 market is small and it is what it is. Also...can't say I really like the shape much either, the front is OK but from the rear it is a dead ringer for a mazda 6
    • Ahh yes looks like I’m playing with a new cock on the weekends. Thanks for the information @soviet_merlin I’ll search for it later on and try to get it shipped. Looks like it won’t happen this weekend regardless. But the coolant looks fine so far (no floaties of concern). And waiting another week will slow down my money hole 😂
    • I don't know whether that one should be reused or not. But here's one way to find the part. Go to https://nissan.epc-data.com and use frame number or the menus to drill down to the parts for your specific car. Looks like it is under 'Body parts -> 214 radiator'. See for example the respective part for my Stagea. Looks like it's called drain cock packing, and at least for mine it is part number 2148118000. Searching for that then gives you various places where you can buy it. Amayama can be a bit slow, so it's worth searching around. I'd make sure it's the correct one for yours. At least from amayama it looks pretty generic and fits a ton of cars. And if anyone asks what you did on the weekend, you can tell them that you put a new cock on the car
    • Because people like Gregged stories, I'll elaborate. I ordered a front end, being a GTR conversion front bumper, CF hood, to go with my URAS wider front fenders. These took a good ~year to arrive. They had arrived when I dropped them off at paint shop 1 and are in that large pile of car panels. Unfortunately _some_ of it didn't fit very well/at all, though to be more accurate it's safer to say it didn't fit with each other. A lot of GTR conversion parts, really are just GTR parts. GTR fiber replicas need GTR guards. Because GTR fenders flare out more than GTT fenders. Even GTT fenders that are flared out by the same amount GTR fenders are. The GTR conversion/GTR bumper I was sold is no longer for sale as the company involved recognized the issues with it and refunded it, beyond this situation. The bonnet and bumper gap was... this. They then sent a redesigned bumper, but this still had the issue with the width, and then advised me I needed GTR bracketry to fit this conversion bumper. Which, to me, is kind of crazy - Because if you need a GTR Reo, headlight supports, headlight brackets, and the mounting bracket (with the additional plate with the rubber strip) in order to mount your 'conversion' bumper, the bumper itself is just a GTR bumper. And when I mentioned this, not to mention the time and hassle of sending bumpers back and a forth and dealing with a busy company, I was able to make the statement that this is not made to fit a GTT at all, at least in the sense that you can't use any of it with any other GTT part. The bonnet worked, but without a bumper that can actually fit it was effectively just a GTR bonnet with GTT hinge points and latch points. Not much use if I can't use a bumper. Why would I (or anyone) buy a fibreglass GTR replica that costs more than an OEM plastic GTR bar, if I need to use all the GTR hardware to mount it anyway? Funny enough I had test fitted everything else except these bits. Obviously I should have. I saw pictures of things fitted but everything's not quite the same and unmentioned the fact people have made extra brackets or something to pull on these fibreglass bumpers. With the GTR brackets we were able to force the "second" bumper they sent us, but you shouldn't need two big guys forcing a fibreglass bumper over mounts you need to drill to get it to fit, using a lot of tension and a lot of force, the whole thing was completely taut and felt spring loaded to explode at any moment. In any case after all this faffing about, I eventually spoke to someone else at this company who advised I should have been sent the correct parts to begin with given they pulled up all my communications with what I had, what I wanted, what parts I was using, etc. But by this time the car had been sitting at Shop 1 for quite some time now and they didn't really just want to paint the rest of the car from A pillar back while this was all sorted out. I got a full refund and honestly everyone involved was perfectly nice and easy to deal with once I could get ahold of them, though it did need a bit of 'chasing' as you kinda expect. So then I had a stock front end again, and could have just fit the URAS fibreglass fronts and used an OEM front bumper and OEM hood and called it a day. But did I do that? No, I am retarded. Because I was paranoid about Mr Police in the future sticking a magnet to my front guards, or my bonnet and realising they weren't metal, I followed up on a tip I got from a friend who got his metal guards widened out. I had wanted to do this 'in the future some day' but thought I may as well just do this 'now' given I'd be driving around all paranoid about my fibreglass front fenders on my otherwise legal and engineered car. SO ANYWAY I engaged these people during the time I was returning the original body parts, so the car was at Shop 1 with no front end at all, not being fitted or being painted A pillar back even though I was more than happy to just get the front panels painted separately when they existed. (I understand the reasoning for not wanting this, but I was just trying to save time). And you guessed it, the metalbenders took much longer than they said they would take, and Shop 1 man had a medical issue where he had to close the shop indefinitely (legitimately).  So even though I had to return a bunch of stuff, and a car sat around for months with no work being done on it, there's no actual bad blood there, so I don't want to name names and say "SHOP X SUCKS" just... do your diligence. Metalbender place returned my Bonnet and Guards to me eventually, which was when I realised THIS: Is going to make my life hard again, because having wider metal guards doesn't make much benefit if the actual point it hits is the connection between the bumper and the guard. Which is why Nissan flared it out, ostensibly.   With regards to the bonnet, I needed vents in the first place because the car likes to overheat due to heat soak on 40C days with the aircon on, if the car has been driven for more than like 30 minutes. Only with the aircon on, only on days that hot, only when sitting, and only after ~30 minutes. So the logic behind it all was to cut vents in. I had originally thought to just the flat pieces out (not the webbing!) and put mesh in there, which would have worked fine. Then talking to the metalbenders I was convinced this was a bit agricultural and water would get in. STUPID EVERYONE INVOLVED didn't think of simply using a plastic engine cover on the engine, and we started talking about vent design and rain gutters instead. There was also the issue of while the guards both fit what I asked for, which was: "Can you replicate these URAS Fibreglass flares on these stock metal guards by the same distance, or maybe +10mm wider?" ..the issue was the guards weren't the same as one another when the job was done. Enough that when I fit them and went to paint places, the overriding feeling was "I can't get it painted while they're like that". So, I Karen'ed and they offered to fix them up to get them symmetrical again after I drove back and showed them, and we did the whole lean back from a few meters in front of the car, and: "Oh yeah" "ahhh yeah".. "Ahh, ... yeah, yeah nah yeah" ... and I then took them off and delivered them. I have it all back now, and while the guards are better they're still not symmetrical, and I'm paranoid about a tiny bit of webbing actually being cut with the vents installed, and only slightly remorseful about the fact that METALBENDING WAS REALLY EXPENSIVE, and it would have been cheaper to simply buy all of the Nissan OEM pieces, including $2200 aluminium bonnets, and $2000 guard sets and OEM plastic bumpers and get it done that way. YOU ARE WARNED. also, anyone wanna buy my GTR brackets between the headlights? Useful for someone doing this conversion and they cost about $1000 cause you didn't want to use/mark up/damage the fibreglass replica the company sold you to make their stuff fit (it won't fit).
