I usually use bp ultimate and got about 400km per tank

But i changed to a k&n filter, 3in turbo back and upped the boost to about 10 psi.(about two weeks ago)

I am now getting about 460-500 per tank (red light for the last 30km)

Everything stock except the above, still using bp ultimate..

I have found in the past that caltex/woolies petrol never gave me as much k's

96 rs4, btw

OK ..... I'll bite.

What's wrong with Mobil?

Had a very expensive experience with my old R31 when I was using Synergy 8000.

Got a bad batch (I guess) and it seized up the car. Turns out everything from the pump to the injectors needed replacing.

The mechanic said it was like someone had put glue on my tank (not possible as the sputtering only started after I filled up on the way to work that day).

It is probably a fine fuel now, but you know how it goes.

Hard to quantify. Last tank gave me 12.5 l / 100, previously its been more like 15. 570 ks per tank vs 450

As I said, I'm trying the 2nd tank now.

As to power, this is seat of the pants stuff. I'm comparing with my 200kw ATW zxtt. Still not as fast, but noticeably better than it was.

hmmm, interesting.

I know it is impossible to replicate exactly, but are you roughly traveling the same route & similar speeds as with the previous tanks?

Need to fill up today... Might give it a go.

As an aside, are there any RS or RX owners getting the 15L/100 mileage that the AR-x owners are getting?

I only ask because I have never travelled less than 615kms from full to when the light comes on.

Even with the exhaust and 1bar max boost I am still getting 630-640kms.

Could the Ar-x be thirstier than an RS/RX?

i pulled the top off the tank one day . the fuel light had come on with in a k of home . we all know how big the tank is . about 3 foot wide and 2 foot long (roughly) (ish) and there was at least 5 inches of fuel in there .

the guy that said it caught him out did it stop while you were driving or would it not start after you parked somewhere . coz as we all know it makes a huge diff if the car is parked on an angle

114.5 :) who cares what they use at this price

That's if your being tight and putting in normal unleaded (has anyone put normal unleaded if so, how does it run). I normally use either 95 (BP 95 Unleaded or Synergy 5000) or 98 (Ulitmate or Synergy 8000) roughly get around 430 - 440 per tank but I haven't ran the tank to light goes on for a while

mobil or BP 98 :D

i just use the normal ULP price as a reference point as i am sure many others do- its on the big signs when driving past :P

  • 1 month later...

Well I'll be damned... I've had the last week off work and managed 11.9L/100km in one tank with the occasional boost but otherwise very wary of being light footed. Usually the mrs drives it 5-6 days a week and I get 13.5-14L/100km. What a difference the driver makes!

Interesting.

Remember that the only cat I have is on the dump, my front pipe has deleted the large cat.

I filled 2 tanks with Vortex98 and let me tell you, my car reeked on rotten eggs, my mate told me that I blew a puff of black smoke when changing gears on high boost and I got ~20km's less for each tank.

After having the next 2 tanks filled with Ultimate, no more smells or black puffs & my economy is back to 620-640km's until the light comes on.

My last 2 tanks have been of Vpower & have been the same as with Ultimate.

I guess that Vortex is a dirtier fuel after all. :cheers:

My trip to work is quite short. At other times I am usually adjusting something like now when I am fine tuning my boost controller (foot flat much of the time) to suit my new turbo so I am getting about 20L per 100km or just over 300k per tank. The best I have ever had is about 13L per 100k ( about 420km per tank). I am stopping spending money on my engine when I install my adjustable exhaust cam gear and then I am going to the top tuner in town and hope to get 200 - 220 AWKW with absolutely smooth acceleration and better fuel consumption when touring.

I am using E10 fuel and i have always figured that the highest octane fuel doesn't cost more because it is more efficient. the standard ecu will adjust for different octanes but it always runs too rich at the top end. For those with computers or other fuel control devices these are usually set to a particular fuel so it doesn't pay to chop and change.

2000 model, stock standard Stagea Type S;

Averaging 420-450km to a tank around town.

Got 9.6L/100km on the Hume Hwy to Sydney last month.

That sound about right? I thought the highway consumption was not too bad (still pretty dodgey around town though ). :(

Stageas are heavy gas guzzlers. Your figures are very good.
Standard s2 rs4v

12.5 - 13.5L/100 - fast country driving running 95vortex

20L/100 - running reg. unleaded :(

I always thought running 91ron and 95ron fuel was not very good for a 98ron car? Seems to be a few people running 95ron in their stags.

Some servos are still pretty dodgy. Some I have been to in tne sticks sell 95 at 98 price Some dont even know which Ron it.

Im still in the 15/16 rut. The hills are fun to drive so I cant complain. Got some real Vortex for 101.9 last week.

    • Yes correct. Also, I'd avoid applying it to soft paint (however I doubt you'll ever have to deal with it in practice). So any paint that hasn't fully hardened, could be a 1k paint that never fully hardened or it could be a 2k paint that was laid down thick and hasn't yet fully hardened. 
    • Bit of an update to this one. Having some issues on the dyno that held us back (boost spiking) and I want to pass some info over you guys and see what you think is wrong with my setup. The current readout on this dyno is 462rwkw on a low reading dyno so keep in mind it is a real world 500rwkw setup on a hub dyno. Don't read into the power figure too much as a sign of the issue. The short and curly of it is: 2.8 Litre Racepace build RB25 NEO N/A Head with VCT (internally standard however ) Borgwarner EFR 8474  Turbosmart 50mm Straight Gate + Mac valve 6Boost Manifold 4" dump to full 4" exhaust (nil restrictions) Wastegate plumbed back in and all angles in the exhaust system are acceptable and not too sharp. GFB SV52 BOV in cooler piping  Turbosmart BOV in EFR Housing   The issue we are having is it comes onto full boost for example at 4000rpm and spikes to 24/25psi, before dropping down to 17psi before slowly rising back up to the target boost of 23psi. It was extremely uncontrollable and the tuner actually had to ramp in boost progrssively with each 1000rpm on each boost setting we selected to try and reduce the amount of spiking. Sometimes we would see a drop of 10psi from the peak at the beginning of the run, to the low, until it took the next 500-1000rpm to stabilise back up to the target boost. The tuner is pretty confident that the straight gate is just a poorly designed product and leaks too much boost upon cracking the gate open and theres no way to fix it other than going to a poppet valve. He's also confient theres no ignition breakdown or floating valves. The fueling is extremely stable as well. Turbo speed is somewhere around the 109,000rpm area. The spanner in the works for me is that prior to this Borgwarner and StraightGate, the car was tuned on -5 twins at a diferent tuner, and he also had issues controlling the boost with it spiking around the same rpm range, so to me this sounds like the same issue and it can't be anything on the turbo side as this was all changed and I think the behaviour is extremely similar, if not the same. We also removed the mac valve and did a run on wastegate pressure and it still spiked and had the same behaviour. My thoughts on possibilities are: Boost Leak VCT Cam Gear isn't reliably activating consistently - (On this however, we did a run with the VCT disabled and the boost still spiked) Turbosmart BOV is not handling the boost? However this seems unlikely to not be able to handle 20psi. I have a couple of logs that I can't make sense of if anybody knows how to read them and can obtain further logs of other parameters if they are not enough, happy to pay for anyones time. The dyno readout with the power figure is the most recent last week. The other picture is from two weeks prior to that where we couldn't break 400kw (we removed the cat), however the issue of the boost control persisted. @Lithium @Piggaz @burn4005 @GTSBoy @discopotato03 I've tagged those that were quite active in recent pages here, no disrespect to those that know turbos well but I missed tagging.

    • I recently purchased a 2018 Infiniti Q60, which has an SD card navigation map. I can see my system has options for real time traffic updates etc, and am wondering if there is something I can purchase to get this working? I can see there are at least updated maps for USA and Canada, but nothing for Australia. Surely Infiniti took changing road systems and city expansions into account when they decided to use an inbuilt navigation over Android Auto/Apple Car Play, or are we doomed to drive on streets that don't exist in the navigation system if you drive to a new area?
    • Luckily I didn't put in etch primer as I just found out it's not compatible with my body filler lol. Also just need to sand the panel anywhere between 150-400 grit so I'm in the clear there. It does say to not apply to soft old paint, I assume that means paint that is flaking, peeling,etc
