I get about 400-450km per tank around town, I guess between 13 & 15L/100km but on the highway it is much better. I drove from Toowong/Brisbane to Penrith/Sydney in ten hours flat only filling once at Coffs Harbour. It was very close to 10L/100km and to do that distance in ten hours is no nana driving. Very happy with highway economy.

I am getting around 10L per 100km's with mine for daily driving... Which i thought wasn't too bad.. Looking at some other Skylines.. my fuel economy isn't too bad... :)

If the price goes to what you guy's are talking about... I better dust off my little 998cc mini for a while.. Leave the Skyline tucked away in the shed... :uh-huh:

I get about 350 to 450 K's out of a tank of BP Ultimate, ATM it is about 96c-98c/litre in Brisbane (bloody expensive)...

I still boost the same tho, I guess I can't help myself. My clutch is rooted now so I am forced to boost less! $2,000 should last more than 8 months on a button clutch, my bad.

It still hurts tho

You guys think you've got it bad for fuel pricing, at the moment and past I have been paying $1.08/L for 98 RON and thats apparently cheap here.

I think i'll be driving the g/f's Excel around for soon.

I drive R32 with cat-back exhaust. Lately i was getting ~ 20L/100km. Found out, when the guy did the timing belt, the exhaust cam was 1 tooth out. Now there is no idling problem, alot more pickup and boost. I'll let you know how the fuel eccon goes.

I get about 600km to a 65l tank most times, and thats with booting it at every roundabout, lights, stop sign :) I once got 623km...

But not many mods, turbo-back 3" zorst, pod, bov, 11psi.

Funny thing is it's running quite rich with the odd flame out back!

Can i crack 650? lmao.

I feel bad for yall, sorry to rub it in..

My 33 only gets 300-320kms out of every tank, but when I go to fill it, its never fit more than 50-55 litres max into the tank.

On the other hand, my b/f's brother has the same year 33 as me (both identical) and he gets 400-500 kms out of every tank..and he thrashes it everywhere!!! Oh - and he has a fuel light, I've never seen a fuel light come on in mine, doesn't matter how empty I run it!!!!!

My user manual for 93 R33 says 65L fuel tank.

Seems a lot of posts on this have been saying only get "x" amount of Kilometes on a tank and can only put "x" amount of fuel in.

If you don't put 65 Litres in then you have not emptied the tank. Different guages will show emptyat different levels.

I would suggest that to check fuel economy:

1. Fill tank and reset trip meter

2. Next time you fill note how much fuel you put in and also how far you have travelled.

3. Do the maths to work out Litres/100 Kilometers

If you work out that you get 10 Litres per 100 Kilometers then you could expect 650 Kms from a 65 L tank.

Note to self: Should do this soon as well

i get 480km/ full tank in my r33, no engine mods at all. This is with a bit of a thrash here and there. Fuel prices here are crazy at the moment, up to as high was 107c/litre for regular unleaded average around 103c/ltr, which means that it's difficult to find Ultimate98 anywhere for under $1.10/litre... not cool.

I am getting around 300 to 350ks from a tank in my stock r33. That is city driving with the occasional Booting. Sometimes as the lights and so on i can smell fuel fumes. I think its actually pretty terrible economy. I had a Non turbo silvia for 3 years and i would always get 450-500k's in city driving from a tank. Not half the car the skyline is though.

    • So, that is it! It is a pretty expensive process with the ATF costing 50-100 per 5 litres, and a mechanic will probably charge plenty because they don't want to do it. Still, considering how dirty my fluid was at 120,000klm I think it would be worth doing more like every 80,000 to keep the trans happy, they are very expensive to replace. The job is not that hard if you have the specialist tools so you can save a bit of money and do it yourself!
    • OK, onto filling. So I don't really have any pics, but will describe the process as best I can. The USDM workshop manual also covers it from TM-285 onwards. First, make sure the drain plug (17mm) is snug. Not too tight yet because it is coming off again. Note it does have a copper washer that you could replace or anneal (heat up with a blow torch) to seal nicely. Remove the fill plug, which has an inhex (I think it was 6mm but didn't check). Then, screw in the fill fitting, making sure it has a suitable o-ring (mine came without but I think it is meant to be supplied). It is important that you only screw it in hand tight. I didn't get a good pic of it, but the fill plug leads to a tube about 70mm long inside the transmission. This sets the factory level for fluid in the trans (above the join line for the pan!) and will take about 3l to fill. You then need to connect your fluid pump to the fitting via a hose, and pump in whatever amount of fluid you removed (maybe 3 litres, in my case 7 litres). If you put in more than 3l, it will spill out when you remove the fitting, so do quickly and with a drain pan underneath. Once you have pumped in the required amount of clean ATF, you start the engine and run it for 3 minutes to let the fluid circulate. Don't run it longer and if possible check the fluid temp is under 40oC (Ecutek shows Auto Trans Fluid temp now, or you could use an infrared temp gun on the bottom of the pan). The manual stresses the bit about fluid temperature because it expands when hot an might result in an underfil. So from here, the factory manual says to do the "spill and fill" again, and I did. That is, put an oil pan under the drain plug and undo it with a 17mm spanner, then watch your expensive fluid fall back out again, you should get about 3 litres.  Then, put the drain plug back in, pump 3 litres back in through the fill plug with the fitting and pump, disconnect the fill fitting and replace the fill plug, start the car and run for another 3 minutes (making sure the temp is still under 40oC). The manual then asks for a 3rd "spill and fill" just like above. I also did that and so had put 13l in by now.  This time they want you to keep the engine running and run the transmission through R and D (I hope the wheels are still off the ground!) for a while, and allow the trans temp to get to 40oC, then engine off. Finally, back under the car and undo the fill plug to let the overfill drain out; it will stop running when fluid is at the top of the levelling tube. According to the factory, that is job done! Post that, I reconnected the fill fitting and pumped in an extra 0.5l. AMS says 1.5l overfill is safe, but I started with less to see how it goes, I will add another 1.0 litres later if I'm still not happy with the hot shifts.
    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers) Replacement of the Valve body (if you removed it) is the "reverse of assembly". Thread the electrical socket back up through the trans case, hold the valve body up and put in the bolts you removed, with the correct lengths in the correct locations Torque for the bolts in 8Nm only so I hope you have that torque wrench handy (it feels really loose). Plug the output speed sensor back in and clip the wiring into the 2 clips, replace the spring clip on the TCM socket and plug it back into the car loom. For the pan, the workshop manual states the following order: Again, the torque is 8Nm only.
    • One other thing to mention from my car before we reassemble and refill. Per that earlier diagram,   There should be 2x B length (40mm) and 6x C length (54mm). So I had incorrectly removed one extra bolt, which I assume was 40mm, but even so I have 4x B and 5x C.  Either, the factory made an assembly error (very unlikely), or someone had been in there before me. I vote for the latter because the TCM part number doesn't match my build date, I suspect the TCM was changed under warranty. This indeed led to much unbolting, rebolting, checking, measuring and swearing under the car.... In the end I left out 1x B bolt and put in a 54mm M6 bolt I already had to make sure it was all correct
    • A couple of notes about the TCM. Firstly, it is integrated into the valve body. If you need to replace the TCM for any reason you are following the procedure above The seppos say these fail all the time. I haven't seen or heard of one on here or locally, but that doesn't mean it can't happen. Finally, Ecutek are now offering tuning for the 7 speed TCM. It is basically like ECU tuning in that you have to buy a license for the computer, and then known parameters can be reset. This is all very new and at the moment they are focussing on more aggressive gear holding in sports or sports+ mode, 2 gear launches for drag racing etc. It doesn't seem to affect shift speed like you can on some transmissions. Importantly for me, by having controllable shift points you can now raise the shift point as well as the ECU rev limit, together allowing it to rev a little higher when that is useful. In manual mode, my car shifts up automatically regardless of what I do which is good (because I don't have to worry about it) but bad (because I can't choose to rev a little higher when convenient).  TCMs can only be tuned from late 2016 onwards, and mine is apparently not one of those although the car build date was August 2016 (presumably a batch of ADM cars were done together, so this will probably be the situation for most ADM cars). No idea about JDM cars, and I'm looking into importing a later model valve body I can swap in. This is the top of my TCM A couple of numbers but no part number. Amayama can't find my specific car but it does say the following for Asia-RHD (interestingly, all out of stock....): So it looks like programable TCM are probably post September 2018 for "Asia RHD". When I read my part number out from Ecutek it was 31705-75X6D which did not match Amayama for my build date (Aug-2016)
