just did a reasonable roadtrip and got 550klms from a tank including around 80klms of town driving from full till the light came on so that would be around 9 or 10ltrs per 100klms? but thats with pretty much stock everything.

On the way from Brisbane to Rockhampton got the following figures:

420kms out of 52.72 ltrs (half town, half highway)

315kms out of 35.16ltrs (All highway)

And man-o-man the rockhamptonites must be getting sore necks by now....... It's like they have never seen a wagon that sneezes ;)

420kms out of 52.72 ltrs = ~12.55l/100kms,

315kms out of 35.16ltrs = ~11.16l/100kms

Dude, these are excellent figures!

Yeah the day before I came up here I had Mercury do a "highway cruise" tune and they did an excellent job eh, there is a tiny issue with it but considering the fuel economy I get while cruising at ~100kph I am more than happy with the results.

Just goes to show what the pfc is capable of for future tunes.

Ive still got a stock ECU and i can get 11L/100 on the freeway.

Not sure whats happend as when i first got the car, i couldnt do better then 14L/100 freeway and 17L city. Now, i get 11L highway and 15L city....interested to get the ITC and DFA tuned

i get between 300 and 350 from 50l round town

400 to 500 on a trip

when i tow my 32 i get about 250 to 300 per tank(60l) does this seem right, what do others get while towing? i've got an safc to go on it before i go down to sa for the first round of the drift australia championship. i'll post up results when i get back

On another note, the other night while driving about 450km of mixed hard driving, cruising at near the speed limiter (~160 most of the time) and city/town, from 68L I got 470km

(I took a jerry can with 15L with me)

So somewhere around under 15L/100. I was quite impressed as there was LOTS of time spent at 5000rpm+

hmmm im getting 200km from a full tank in city driving and 400km for highway driving.... i thought this was normal but obviously im having some dramas. Im not getting any backfire etc (well occasionally when changing down gears and slowing down) but i didnt think i was running too rich.... im having some fun parts put in soon so hopefully with the retune ill run more power and better fuel, 200km off a full tank is rediculous

SK reported improvements of around 1L/100 after the DFA was installed.

I am certain it would make a massive difference. I think I might give the DFA a quick tune for the time being after I install the turbo, until I can afford to get the cams/unichip done. At least I will get a bit more power and better economy until I can afford it.

what's a DFA?

One thing to keep in mind looking at this thread, is we've got at least two types of stageas being compared - series 1 versions (which I have) and series 2 versions (neo engine?) , then also possibly some later model ones with the VQ series engine ? If there are people comparing fuel consumption of the VQ series engine with the RB, I reckon the VQ will win hands down, as anyone who has owned a Maxima will attest, they are fantastic engines and very efficient.

Unfortunately, I have an early model, series 1 stagea, and was initially appalled at the fuel economy of the stock vehicle. Now after 18 months or so of ownership, we're consistently getting 520 to 540 km out of a tank (55-58 L fill). Mostly commuting, and running around in short to medium trips, rarely in peak hour traffic. If you want to know what I put this down to, it includes (in order of merit)

Jaycar Digital fuel adjuster -- don't leave home without it, worth about 10% improvement

Revised valve body for the auto from the guys in Adelaide, worth about a 10% improvement I reckon

behaviour - light foot and drive around with converter locked up in overdrive as much as possible

3 inch free flow exhaust and K&N panel filter - let her breathe

Iridium spark plugs - they extend the lean misfire limit allowing me to tune the DFA leaner at cruise.

keep tyre pressures above 35 psi (heavy car)

These are the mods that have got us from the original 15-17 L/100 km when we bought the car, to the now manageable and repeatable 10 - 11 L/100 km. In fact, we now get the same fuel economy towing my gazelle and trailer (total 1500 kg) than we did with the original stock car in an unladen state ! Not bad for a series 1 RS4 auto.......

In fact, I haven't been on a long run since the valve body upgrade in the auto, which has made such a dramatic improvement in performance and economy, that I reckon next time we go for a long drive, a high 9 L per 100 km will be on the cards for sure.

Quick question, when does the fuel light come on? Is it when the actual fuel gauge is showing at or below Empty?

I don't wanna find out the hard way that my fuel light doesn't work - unless I carry a Jerry Can around (which I'd rather not do).

In my old Corolla, the fuel warning light would come on as soon as it hit a quarter tank, so I always knew where I stood.

    • ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.
    • And if you have to drill the oil block, then just drill it for 1/4" and tap it BSP and get a 1/8 to 1/4 BSP bush. The Nissan sender will go straight in and the bush will suit the newly tapped hole. And it will be real strong, to boot.
    • No it doesn't. It just needs an ezy-out to pull that broken bit of alloy out of the hole and presto chango - it will be back to being a 1/8" hole tapped NPT. as per @MBS206 recco. That would be for making what you had in alloy, in steel. If you wanted to do just that instead of remote mounting like @Duncan and I have been pushing. A steel fitting would be unbreakable (compared to that tragically skinny little alloy adapter). But remote mounting would almost certainly be 10x better. Small engineering shops abound all over the place. A lathe and 10 minutes of time = 2x six packs.
    • Ahh. Well the block damage is a problem, you really need to run a tap or thread chaser through it to see if the threads can be saved, but any chips are likely to be bottom end bound which is bad. Earls seem to have what you need if you want to stick with mounting direct on the block: https://rceperformance.com.au/parts/earls-straight-adapter-1-8-npt-male-to-1-8-bspt-female.html, but as I said above I'd recommend remote mounting the sender
    • I'm not quite understanding or I'm missing steps here, (I appreciate people are trying to inform my brain but I am of the dumb, especially today) - All I want to do is mount the male BSPT of the OEM sender into the system somewhere without it snapping the adapter via vibration. The Nissan sender has a male 1/8 BSPT output. The block has a (very destroyed) 1/8 NPT input. I'm not really sure how a lathe assists with that, and also don't know anybody with a lathe, nor specifically what I would want to buy. I'm not really sure how adding additional adapters creates a better, more leak proof resilient seal here.
