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!

    • I'm looking for some real world experiences/feed back from anyone who has personally ran a EFR7670 with a 1.05 exhaust housing or a .83 I'm leaning towards the .83 because its a street car used mostly for spirited driving in the canyons roads. I"m not looking for big numbers on paper. I want a responsive powerband that will be very linear to 8000 rpm. I dont mind if power remains somewhat flat but dont want power to drop off on top. The turbo I've purchased is a 1.05, although the mounting flange T3 vs T4 and internal vs external waste gates are different on both housings, I not concern about swapping parts or making fabrication mods to get what I want. Based on some of the research I've done with chat gpt, the 1.05 housing seems to be the way to go with slightly more lag and future proofing for more mods but recommends .83 for best response/street car setup. AI doesn't have the same emotions as real people driving a GTR so I think you guys will be able to give me better feed back 😀   
    • Surely somebody has one in VIC. Have you asked at any shops?  Is this the yearly inspection or did you get a canary?
    • This is where I share pain with you, @Duncan. The move to change so many cooling system pieces to plastic is a killer! Plastic end tanks and a few plastic hose flanges on my car's fail after so little time.  Curious about the need for a bigger rad, is that just for long sessions in the summer or because the car generally needs more cooling?
    • 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.
