You cannot possibly compare fuel economy of 2-3 different branded fuels unless you drive the exact same route, with the exact same tire pressures, load, and everything else you can't replicate...

yer i get what your saying, its just when i was using shell i was getting 450 and nothing over it for the 2 months i was using it as soon as i was using ultimate i cracked 500 about 3 weeks into using it.

I by no means drive the same route, although my tyre pressure will be very similar as i fill it up every week after i fill up fuel and as for the load it may vary a few kgs.

I believe i did get better fuel economy using ultimate as i can get over 500kms now which i never could with shell no matter how much i Grannyd it and how many hwy kms i drove. (to an extent)

Not comparing to 3 different types just the 2 im sure you will also find many people on this forum that can compare one fuel to another and notice better economy...

Personally from my experience it depends on where the servo is located. I noticed the inner city suburbs tend to have better fuels.

I have no hard evidence to prove it, but i do notice the car tends to run smoother and have a little bit more urge when I fill up at the inner city servos. :S

well that would make sense, inner city suburbs stores churn through more fuel

so they fill up from the main tankers more often so the fuel is always fresh

when fuel remains in the takes for longer, it looses its octane rating over time (unsure how long)

so a less busy servo is more likely to have more-stale fuel in its main tanks

I can say I have the same problem at the moment. I work for BP Head office and the last 4 tanks of fuel I have put in of Ultimate have made my car run like a shitty old falcon (read bag of shit). I don't know what has happened in the refining process but I filled up at 3 different servos. BP Melton, BP Taylors Lakes and BP Swan Street Richmond. Different trucks filled up each location and they were different weeks, I ran a tank of Vortex through before the BP and I gotta say my car ran better on it. Mobil it ran okay too and Shell it runs like shit again. Also V-Power goes stale much faster than the others do both in the car and in the ground.

I am thinking of calling in to one of the depots and picking up some toluene for a burn.

I will not be putting BP in again until they sort the problem with the fuel out. Will be Vortex for me for a while.

On a side note you can't get V-Power racing anymore, they stopped making it ages ago and anyone who is still selling it is either getting rid of the stale months old crap they have left, or, is selling standard V-Power as Racing (they do it too). United 100 octane has more ethanol in it but like an earlier post said I don't think they make it anymore due to lack of sales for such a niche fuel.

There are no bad batches of fuel, it all comes from the same place. If there is an issue then it would most likely reside at site level. I would suggest that you contact bp if you believe there is a problem with the fuel that you purchased. See the link below for bp's Fuel Guarantee, and some other info that might be of use.

Dirk Diggler, I would thought working for bp you would raise this as an issue with one of the business managers. From your post, you put Vortex in first, and all others after ran crap, so maybe that was the issue if your particular problem is related to fuel quality. Or it might be your car? And Toluene will end up giving you sooty spark plugs due to the high carbon content.

Well at this point in time im going to change to either synergy or vortex lol

Opinions on them? my cars stock :P

Hey bro, I havent tried anything else apart from shell v-power; I was under the impresion that all these premium fuels had to be 98octane??

Ill try some synergy, vortex etc. next time and check my knocks on the pfchc

Maybe go for shell cos i havent had any problems with it.

Well at this point in time im going to change to either synergy or vortex lol

Don't know what it is like now, but the last time I used Mobil Synergy 8000, the old R31 seized and the entire fuel system needed to be replaced (including pump) and was directly attributed to poor fuel. I used to fill up exclusively with 8000, but that was about 6 years ago. No way that is going in my NM35.

I usually fill up on either V-Power or Ultimate and I have found that the car gets better mileage on the BP (~650kms before the light comes on, compared to ~620kms with V-Power).

Oh, and my brother used to work at Safeway Petrol and gave me some real horror stories about their fuel... So I don't really use Caltex either.

Hey mate,

There are such things as bad batches of fuel, they do come out of the same place, what I should have said is that it depends on the in ground tanks at the site and how old the fuel is.. I will be raising the issue at work on Monday and see what happens as 4 tanks from 3 high volume servos that have all been bad is a bit much!

I used Vortex this weekend and have not had an issue.

Could be my car and I am not ruling that out yet as have had a few issues couple of weeks ago that could be the cause, but I like to blame the fuel as it's easier to do and I am not the only one nor is the OP, who have fuel problems from questionable fuel quality

I also had fuel problem befor my car got written off, befor then i always had stalling while rolling, bad when starting the car, powerloss when i hit 3k rev and wont go over that because fuel cut out, and all sort of trouble, i look every where on forum saying it gremlin problem, tried changing my fuel pump relay nothin, my afm nothin, fuel filter nothin, coil packs fine, plugs fine, either was fuel pump or a fuel leak some where. so while i pre app i ask my teacher if i can chuck car on hoist which he let me and look at the fuel lines nothin all good and then look at the tank, because when i filled my car to full tank it always leaked abit from some where and i ask a friend he said all cars to that if u over fill it im like ok , so i check it anyway and it eneded up the brather hose from my fuel tank which had a massive crack so every time i hit a left corner i got fuel leak and fuel smell in my car and also bit of air went in the lines which made me have those problem changed the hose $10 and all fixed till i smashed it the next day :mad: :mad: :PBJ: :( :( :drag::mad: sorry for life story dood but had no problem useing fuel with Mobile 98 and shell, even United 98 is good i heard united buy 98 from shell and sell it cheaper than shell so i go united when ever i dont have discount for shell lolz

Edited by BRUNSKIGTST

well from what i have researched this is what i have picked up on each fuel from everyone.

BP Ultimate - GOOD lol

Caltex Vortex - Mixed opinions, few horror stories

Shell V-Power - Good although octane drops alot quicker and leaves u with a dirty rear bar.

Mobil Synergy 8000 - Same as vortex

I have heard mobil do not have any ethanol in their fuel, is this a good or a bad thing?

hi everyone im from SA i have had the same problem from BP Ultimate over the past few months, it would have good days but bad days as well but with the same responce as your car so i use mobil 8000 and no problem i find its a bit more responsive as well

Hey all!

I live in the western suburbs and recently filled my tank up (42 odd litres) of BP Ultimate, i then noticed as soon as i drove it for a while something wasn't right!

The car was idling not necessarily rough but out of tune, turning it on was also a struggle as it would stall or want to..

bp ultimate/vortex 98 is what i use, never had a problem

your car must have the gheys :thumbsup:

Bp Ultimate is 98, but im sure our vortex is caltex fuel and it's 96 not 98, and shell v-power is 98 but to much ethonol (spelling)

Did your mates dad test for any contaminants?

I'd suggest it is related to the servo you visted, not related to the type/brand of fuel

and/or original source, otherwise we'd here a heap of other people complaining, not

so much in this forum but in the public arena also.

I highly doubt the owners/staff adding anything to the fuel also.

Does it look like a dodgy servo, not looked after/run down?

There was a suggestion of tanks getting low and picking up crap.

The tank/pump systems are filtered so this would have to be screwed also.

Entry points for the crap into the servo's tanks... take note of the breather pipes

sticking about 3metres out of the ground, they look like the breather pipe out the back

of your house near the dunny. Have they got caps at the top to stop crap falling in

from overhaning trees etc...?

(from memory sometimes there's no cap but a flared top with mesh or a litle raised/vented lid)

Also if you wish to have a further sticky beak around the servo :), lift up dip dipstic

cap(s) on the ground they are a thick metal disc with a little cut out, check there's a big

brass screw cap there and it's sealed.

If i'ts not a screw cap probably a lever type brass cap, again check it's sealed, if not take a quick

pick with your phone, bit of data/leverage to possibly work with at a later stage.

There should be some similar one's for the fillers as well where the tankers plug in.

Other than that I can only think of a cracked tank which is very rare as they are built to last and i mean last...

In this regard i could only think land movement, given the dry conditions over recent years.

Is the ground your walking on at the servo cracked everywhere, repaired patchy concrete

Although if the staff see you what are the outcomes.....they call security, cops, big argument who knows..

Perhaps politely ask the onsite staff member/manager before doing so, as really they should not have

anything to hide and may help out.

Gilbarco is the company that usually sets all the pumps up, services and test etc.. not sure about the

tank, fuel contamination side of things.

There's a weights/measurements govt dept. if memory serves me correct, to complain about

the pump putting out the wrong fuel amount..again not sure about contaminants.

I used to work in a servo b4 anyone asks.

The owners dont make much of the fuel, if at all, sometimes it has to be subsidised for the local / franchise

owner by the Petroleum company to balance things out. (my givem a fair go bit)

Not sure how it is these days worse/better.

They have to make a lot of the money of instore product, hence the prices :thumbsup:

See how you go, hope I havent put in grand/bad ideas in your's or anyone's head, just a fyi, something to

work with.

..................

My Fuel's Used

20-30km daily driver approx

Start/Stop Traffic

Safeway Vortex 2-3 months straight no issue. 320-350km

Shell V-Power 2-3 months straight no issue. 340-370km

Last six month there abouts alternate between the two.

V-Power makes the car drive just that little bit better in my opinion.

BP Ultimate one or twice. 300km approx

Mobile ??? what is it.. one or twice. 300km approx

I drove a bit harder when using these so no comment on the economy side of things :rofl:

As for the ethanol fuels well no comment as yet with the series 2 stag havent touched

it although thinking about it. However Nissan don't recommend it on pre 200? something

vehicles.

However on my R31 (rip) it used to love ethanol, slighly advanced ignition, ford xr6 4 spray injectors

from an el i think, extractors and pod, nothin else, get around 300-600km depending on my foot

with a mix of start/stop driving and open road. This also had all new high pressure efi hose throughout,

where ever i found it old stuff, put new stuff in.

Best in the R31 was 810km hwy trip one tank, think there was something like 3-5 litres

left in the tank, went put put put around one corner near home then on the straight it picked up

again...headed straight for he servo..... it was amusing but not the best thing to do.

This was using BP Ultimate. I went past Wangaratta somewhere and back, with 1 drive locally to pick

up booze and no more driving untill we went home a few days later.

I better shut up now, sorry for the biblical sized reply, just noticed the scroll bar, got in some sought of typing zone.

    • Keen to see the turbosmart data, to date I've only seen negative things in terms of response for them. Very small sample size though.     Hawkins is a big advocate in his videos of the larger rear housings. I managed to make similar power with a lower spec motor on the smaller .8 rear, keeping decentish spool.  The people he works with now are big power cars compared to mine though, mine really is setup to drive around and enjoy.  I don't have any back pressure monitoring though, so couldn't say if its good or bad on my car, just that it does what I want it to do.   Future I want a higher compression more cubes motor to give a bit more bottom end and hopefully the new g35-1150 gets me to the 850 rear comfortably.  But maybe I won't due to exhaust back pressure.
    • No, I refuse to buy their cheap ass crap! I do need to order a bunch of different nuts/bolts to refill my nut/bolt wall though. Maybe you could go for a walk through Bunnings for me? (Or send me some stuff from your work? )   I really struggle to work out how the US standardised to Metric in what the 70s or 80s, and yet, half a century later, there's been little done to actually bring it into fruition. It truly baffles me    On the whole Fastenal thing, I went reading their site (My god they sell a lot of varied stuff!), and it seems like it really depends what store you're near if you can walk in and just grab a few small things, or if that branch is primarily distribution with only a small window of "counter time" available (if at all). That definitely makes it harder, as move locations and it drastically changes your ability for success   For things like your M6x1.0, if you want to work on your own Skyline, and you also have a "home workshop" I'd recommend setting yourself up a small Nut/Bolt wall/section. It doesn't even need to be big at all. Most things depending on the diameter, will be a specific pitch, like the M6x1, M5x0.7 etc. Bigger bolts is mostly 1.5, except for a small number of things and that will come down to torque. From memory bolts for the brake calipers (and other things that need a lot of torque) will end up being a 1.25mm pitch. Save up a few dollars, and order a range of nuts/bolts. If you want to minimise cost a little, buy something like M6 x 40, and M6x70mm (1mm pitch) in both. In addition, buy yourself an M6x1mm thread chaser. That way you have long bolts that you can cut down to size, and then chase the threads out. Funnily enough, I find what I'd pay here for ordering 5 bolts, I can pay about 50% more and you'll get 100 of them.   If that doesn't quite work out due to space / ability to buy plenty up front, then each time you need some bolts, order 100 of what ever you're getting. Put them in clearly marked containers. Over a few years, you'll acquire plenty of different sizes, and will end up ordering less and less. And the cost for 100 bolts won't be much more than you paid for your 5 you needed to order anyway  Just takes a little planning ahead, by investigating what nuts/bolts you'll need, and ordering them before doing the job.     Edit: If it's also primarily for working on just the Skyline, for some reason my brain is screaming that at some point, either Nissan, Nismo, (Or possibly a third party) was selling a "kit" of every nut and bolt in a Skyline, purely for people restoring/rebuilding. It'd likely be quite expensive, but would give you every/any nut/bolt you need for stock/factory things. I'm not sure if it's still available, or even if it actually fully came to market, it's just something niggling in the back of my brain that you could look into further if that sort of thing interested you? (It might have been for the R32 GTR or something specifically too, and not just any Skyline)
    • 90lb/min @ 20psi is wonderful, not so much of a problem with the G35-1050's compressor efficiency (aside from how bad they roll back at higher pressure ratios).  The issue is more to do with the turbine's flow, which is why I'm not sold on going an even higher flowing compressor with the same turbine.  I'd say go back over Motive DVD's testing of the G35 1050 and Hawkins's comments regarding exhaust back pressure issues with it, I'd need to go back but I have in my head he went to the biggest hotside and ended up sacrificing a lot of spool (so it ended up behaving like a bigger turbo) and still had EMAP issues.  I've heard various other experiences along the lines of that. At this stage at least I rate all I've seen about Xonas (for transparency I've not used one directly, but I have spoke plenty with people who have) to have low exhaust restriction for the response they offer for any given setup - basically they allow the engine to breathe, which is good for the engine and makes making power a lot easier.  You arguably don't have to even push quite the same amount of airflow through an engine to make the same power if you don't have the bum plugged up with exhaust gas struggling to escape the engine due to an underflowing turbine.   In terms of reliability, to be fair I've had great luck with Garrett turbos as well - my GT3076R lasted forever, then I sold it and the next owner had no issues, then that car got sold and it was still going strong last I ever heard about it.  The trick is with the old GT-series turbos the compressors etc were no way near as efficient as what we have these days, it was almost hard to push them into severe overspeed situations without having a boost leak or something - and that is what often starts the failure situation.    In terms of your G35 I'm pretty sure you're running yours within sensible limits, something people with Xonas and Precision turbos aren't often so inclined to do.  The "compressor maps" are "Joe blogs ran 45psi through his 6466 so I can do the same" and built their setup to send it to the moon.  I've seen EMAP and compressor speed data where people have actually set that stuff up on Precisions and Xonas which have been run hard and the comp speed numbers are very very exciting at times - like I've seen 76mm Precisions run at rpm that you ideally shouldn't run a G35 1050 lol.   I know people who have run G-series Garretts hard and hard a failure, then replaced them with Pulsar turbos as a cheap "get it going" stop gap with the intent of doing a proper upgrade when THAT fails... and are still running the same thing.   Like anything, ymmv and it's not always to do with the quality or trustworthiness of said product. I've been provided with a bunch of compressor maps for Turbosmart turbos and will update my list based off that, they could prove to interesting reading and an interesting alternative as well.
    • Just cage it, call it a race car, and then fall in love with the chirp chirps through pit area!   Also, this is coming from someone with a completely locked diff...
    • I still have an old R32R left over from when they were a thing in the early 2000's. It was, for its time, done about right. But its time was 20 years ago.  I did try and update it a while back but it was cruelled by a (recommended) muppet of a tuna who couldnt tell his MAP from his TPS. The original spec was: Power FC, 700cc Sards, Nismo pump, 2860-5's, cams (Basically Poncam A's), Z32 AFM's and a half sorted oiling system. Thereabouts 430rwhp irrespective of what was done. So, yeah, very 1990's. I eventually got sick of it not being very refined and bought a Link G4 PNP with some 1000cc Bosch injectors. This was tuned badly and I put the car in the shed for a few years whilst I sulked and went and did other things. Ive come around to the idea of getting it going again so it has a new gearbox installed and some other minor things in the planning. So my questions are, variously (In the context of keeping the Link) What other sensors should I be running eg It has no wideband on it at the moment, nor fuel pressure. $? Is it worth chucking the old ignition system (ignitors etc) for new ignition coils? $2k? Cam/crank angle sensors? Can keep the aircon? $? Anything else? Sorry to launch another what should I do with my car thread but, you know, what should I do with my car? Random photo for historical context.
