Hey guys,

Just out of curiosity when do you guys fill your tanks? I know i personally do mine once a week, usually on a Tuesday. This is regardless on how much fuel i have. Whethers its 3/4 tanks left or 1/2 tank etc etc.

Recently ive only been doing 150-200 clicks per week in the sky.. which is leaves me inbetween 1/2 and 3/4 tank. This is because of two reasons. The first it is cheaper during the start of the week and the second being its not good for the fuel pump if the fuel is too low. If i keep topping up from that level, would that mean there may be some old old fuel still kicking around in there. Or does it not really matter when the fresh stuff is all mixed in?

Type of Fuel i use: BP Ultimate Ron 98. Filled mostly at the same petrol station using the same bowser...

Hey bud

It really doesn't matter if you fill up constantly or when the light comes on, the fuel pump is at the bottom of the tank so its naturally a first-in-first-out system. Stale fuel is also a myth, a few of the boys had their fuel pumps and filters taken out and there was no deposits or gunk found in them.

I'd only be a little precautions if you have an aftermarket fuel pump as they don't like it as much when you're running on empty but if you have a stock one its totally fine.

Here's a similar thread to yours with a bit more info

Hmmm... That's not that much mileage for that amount of fuel...

Half a tank will get me about 250 km's and 3/4 will get me over 300 km's...

I think the fuel at the bottom of the tank will go first before the fuel at the top just after you finished filling up petrol.

Next time, empty a tank to about 3/4 and the pour some injector cleaner in then fill up the tank to mix up the injector cleaner.

Next service, change your fuel filter and see how you go.

I ran mine out of fuel once, thinking that the fuel light got me the same milage (50km) as the VN lol. If you ever run out, don't bother only putting in 5L, as it won't start, and will lead to compounded frustration :D

I did the fuel filter when I bought mine, I wouldn't anxiously be doing it again in a hurry ha ha ha.

Otherwise when it starts to go under a quarter I generally try to put fuel in it (usually have to drive 35km to a decent servo as the ones here only sell ethanol crap 95 :S)

Notice how i said "leaves me in between 1/2 and 3/4 tank." . This means Ive used only 1/4 tank of fuel. Leaving 3/4's of it left in the tank. Half tank on the dot will see me around 245kms.

Usually when i pump on tuesday's it will only cost me 25ish dollars to fill to the top.

Thanks for your replies guys... ill keep topping it up weekly then =)

Cars never been under 1/4 of a tank. Always BP Ultimate 98 and I always put $50 in and that $50 usually gets me 300k's. No idea what a full tank would get me as I've never used a full tank :)

Anyone else have this problem; after filling up, the needle will not budge from FULL for about 100-150k's then in the next 100k's or so it will go all the way down to 1/4 full?

Ah ok I get you now. Haha!

I take back what I said...

Im pretty sure this just has something to do with the way the fuel tank is in the skylines, They all seem to do it to some degree

Pretty sure the tank is tapered so that theres less volume at the top and more down the bottom. But ive never had mine out so not so sure lol

With my 34, whenever I fill it up full, the needle sits above the FULL for about 70km, then it will drop to down to FULL.

But yea, each 1/4 gives me different mileage, first 1/4 can give me more than second 1/4, but it doesn't really bother me, as I just fill up every tues/wed anyway.

I fill up every 2 or 3 days. Normally get 450kms to a tank from full to sitting on the empty line. I've had the fuel light come on a couple of times but never ran out. I should probably get a daily lol :)

Not sure with a R32, but I've noticed with the R33, R34, when the fuel light comes on, there's still about 15L left in the bank :)

I'd only be a little precautions if you have an aftermarket fuel pump as they don't like it as much when you're running on empty but if you have a stock one its totally fine.

Do you know why its bad for aftermarket pumps? I was told the samething by the mechnical who installed the aftermarket pump (BOSCH intank) when my old stock one died, but he didn't explain the reason.

This happened to me the last time I filled up, was too busy with all of the Uni sh*t going on & I forgot to fill up & was driving around with the needle on E & the fuel light on, I noticed while driving around slowly at the car park the fuel pump was making some loud whinning noises from time to time, scared the crap outta me & I pulled into the closest BP I could find & just filled $10 worth of RON 98. The fuel needle went ontop of E & the pump stopped making that whinning noise.

Later that day, went to my usual Caltex & filled up to full using my parent's shopping discount card :D

I think I've read it somewhere before, someone said that aftermarket pump won't suck up the last 1/3 of the tank or something :P

both those statements are incorrect. the fuel put into the tank will mix with the fuel in the tank already when filling up and then again when you drive along the road as it sloshes around in the tank. also stale fuel is real. go find a car sitting at a wreckers that has been there for a while (like a year or 2) and pull a fuel line off and inspect what comes out. you won't get a car to run on it very well. the higher the octane of the fuel, the faster it goes stale (loses it's octane rating).

I think I've read it somewhere before, someone said that aftermarket pump won't suck up the last 1/3 of the tank or something :woot:

that is usually because it has been mounted incorrectly. when i put an 040 in a mates 33 i made sure it sat nice and low and he didn't have any issues with running it down until the light came on.

the biggest issue with letting the tank run low is that you start to suck up any crap at the bottom of the tank. when there is a lower concentration of the junk (since it all settles on the bottom when the car is stopped). however once you have run the tank down a few times there won't be much crap left in the tank, it will all be in the filter. i opened up the fuel filter from my magna once day and it was full of crap. even just letting the fuel flow out where it normally went it was enough to get your hand covered in debris.

    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
