That is extreme.. I don't do much highway driving, but the best I have done in the past was about 730km with just a smidge under 1/4 tank showing on the gauge. Wasn't economy driving.. sat on 100-110km/h, 4 people in the car with a boot load of luggage. After re-filling the tank, it worked out to 7.6L/100km. theoretically, an 80L tank should be able to do over 1000km with that figure, but no-way would I push it that far!

Hybrids don't do that well on the highway anyway. They shine in the city.

@sonicii So the tank size is 80L yeah? Cze I have a friend who has a 2005 V35 coupe and he keeps saying that his car does not have a 80L tank.. is it different from series 1 to 2 in terms of fuel tank size?

Yes they are 80L trust me :)

I have filled up 76.41L at a servo & was still running on Reserve at the time..

Petrol Light can take you 75kms from memory :)

I was trying to look for my notes before posting my response, but don't know where I dotted them down!!! :(

Here we are...

The 14.7kms per Litre & 15.7kms per Litre snap shot readings prior the English Conversion.

I have managed 16.7kms per Litre but no snapshot for proof...

I will upload my 'Hypermiling' records with the English Coversion readings in April :)

Stay tuned peeps...

Same with the M35 Stageas, the gauges seem fairly...approximate. I've noticed mine now seems to get down to a bit below a quarter, then bounce back up to a bit below half. I've just taken to filling up every 4-500km and seem to get 50-60 litres in the tank at that point depending on the mix of driving.

You can fix this with a cotton tip :-)

Take your back seat off, open your fuel lids, pull out the sensors and clean the metal contacts with the cotton tip.

Make sure you change the Orings for the tank lid, good opportunity to change the fuel filter too.

Correct, my V35 Skyline would always show over full for at least the first 40-50 kms :)

Mine does the same. At first I though my fuel sensor was faulty as id didnt start to drop until I had done 50-60kms.

Just out of curiosity, has anyone with an auto coupe worked out the fuel consumption if they only drove with the little switch near the shifter set to snow or power? I think it would be interesting to see if snow saves you fuel, or if its just a rumour...

I doubt it would make any improvement.. in fact it may make it worse.. you would need more throttle input to accelerate the same, meaning you have more TC slip, which wastes power in heat.

These engines don't really benefit much with lower RPM with economy. My V35 returns better highway fuel economy than my wife's J31 maxima, despite the V35 running about 500RPM higher at 100km/h

I am getting 6.5L-6.8L per 100kms travel readings so far.

That is from Sydney to Newcastle distances & cruising between 90km-115km p/h depending on hill or downslope!

Tomorrow & Thursday is the time where I start to test it out further as I have 1,600km to do :)

I have finally completed the testing over the weekend @ Hay Plains, NSW.

Balranald to Hay.

6.0L/100kms (60-65km p/h) Distance: 1,333kms!

6.1L/100kms (---) Distance: 1,311kms!

6.2L/100kms (70-75km/p/h) Distance: 1,290kms!

6.3L/100kms (---) Distance: 1,269kms!

6.4L/100kms (---) Distance: 1,250kms!

6.5L/100kms (---) Distance: 1,230kms!

6.6L/100kms (---) Distance: 1,212kms!

6.7L/100kms (---) Distance: 1,194kms!

6.8L/100kms (---) Distance: 1,176kms!

6.9L/100kms (---) Distance: 1,159kms!

7.0L/100kms (---) Distance: 1,142kms!

Formula: 80L/6.0L=1,333kms

Consumption depends on speed, throttle pressure & endulation (flat to hills).

My constant consumption sits on 6.8L on the highway :)

Fuel Range Readings are nearly always innacurate.

As it requires hundreds kms of driving on the same fuel consumption profile for it to deliver an accurate reading!!!

But the above math formula does the work for you :)

Enjoy...

Hey Paul, where did you get your software conversion done from?

Nagoya Motors in Caringbah, NSW do them.

I have a 2001 300GT, it does about 12.5L/100km daily (driving to work, a bit start and stop, but also some motorway driving, about a 20km trip each way) and 10L/100km on the motorway.

    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
