you cant always blame the fuel because your car pinged you have to try and factor in all the invariables

my car occasionally pings but I'm running 12.5-13 psi on a stock ECU

when it pings the weather is normally a bit warmer too

Due to price of this fuel i think i'd be better off with BP too... i've got the bp mastercard as well so it's worth it.

I've always used the Shell premium / Vpower, no worries. BP's in my area are always up at least 5c more on Ultimate compared to Vpower at Shell across the other side of my suburb!

Your prob wasting that 5c per litre saving driving "over to the other side of your suburb"

Ive only ever used Ultimate, thats what my car is tuned on so thats what i run!!!

i have always used BP ultimate and never had a problem with it....i have tried the shell Vpower for a while and the BP ultimate for me last longer then the Vpower and there isnt a huge difference but just because there is a BP near me i use the ultimate.....

the 94 product is just unleaded (91 RON) + ethanol = 94 RON

the 98 product is just premium unleaded (95 RON) + ethanol = 98 RON

if they added ethanol to 98 you get 100 RON or thereabouts

the ethanol adds 2-4 RON

Yeah Deluxe, and my car was tuned on cat piss. I better stop going to shell hey.

Are you seriously that uptight about your fuel?

There is a very good reason to be uptight about fuel used.

If the car is tuned for regular 98ron fuel and you go dropping an ethenol blend in it the car will lean out; egt's will raise, the motor will possibly ping/detonate or throw that ceramic turbine wheel.

I have had the odd tank of Mobil 98 that has shown higher levels of det when the car was previously tuned much closer to the det threshold. Dangerman4 actually saw less det with shell vpower.

For a car that is tuned right to the edge it is I think a wise idea to stick to a given brand of petrol.

im always gonna use BP Ultimate

when i first got the car i was using BP, then a couple of months later went to Shell V-Power, i lost 7 kW by using V-power, so i went straight back to BP ultimate, the car wasnt too happy for the first couple of tank fulls, but sorted itself out, and now i wont use anything else but BP. the car is now tuned on it + Justice Brothers Octane Booster

f**k oath im the same, only ever run the one fuel that being ultimate, i will keep driving until i find a bp

i drive from mclaren vale to christies beach to get bp :thumbsup:

bipass the shell in mclaren vale and liberty on victor/south road to get there

Nah not at all, Have paid upto $1.46 for premium the other week! But what you said is like finding $5 in your bedroom and going "sweet i'm gonna go drive to the servo and put $5 petrol in and drive home" Pointless........

But yeh as Joel says, its what your car is tuned on is whats best for it, But a regularly used servo is also the key, the fresher the fuel the better for it, besides the cops use Mobil, so thats outa the question.... :)

interesting points!

Lucky for me, my motor has never suffered pinging or detonation. I've filled my car up with several types of premium except for liberty's/united's.

I have had my 33 for 6 years though... So call me experimental; i've been lucky to never cop a bad dose of premium juice, whether it be Shell, Caltex, Mobil or BP.

will take these suggestions into consideration! :worship:

MSPEC33,

Within the 6years and 180,000km's of owning mine I've only ever had one noticeably bad batch of fuel; happened to be Mobil 8000.

Pinging was audible; similiar as to how it ran with 95ron so at a guess I suspect they dropped the wrong fuel in to the incorrect tank.

At the time the car was still on the stock ecu and running 1bar.

moderate mods sinista, nothing too mental.

yeah i remember that fuel Cubes, was the purple pump with the 'Synergy' label wasnt it?

before BP ultimate was widely available like today with all the 'on the run' servos, it was actually the Mobil 'synergy' premium that a lot of people reccommended!

    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
    • OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
