Seriously don't even contemplate it.

If you can't afford 98 ron then you can't afford to maintain the vehicle and its associated running costs.

i.e ... many years ago before 98 was available I owned my first import a S13 CA18DET. 3 weeks on 95 was all it took to do the head in... you could hear the detonation.... I was 18ish (I think) and didn't even think about throwing octane booster in the tank at the time.

If you must run the car on *shudders* 91 or 95 (better) then see if you borrow a knock monitor off someone to monitor the detonation.... also keep a light throttle and out of boost where possible...... If you can hear it pinging constantly then its only a matter of time before the rebuild fairy will be coming to visit.....

actually, youre all being stingy with the fuel you put in your cars (yes everyone) your using the inferior 98 octane when you can use AVGAS 100 !!!!

but seriously you bought, and now drive a high performance, expensive and classy car, the price of these privliges is having to put in higher grade fuel, but if you think about it is that so bad?, 98 octane does give you increased performance and economy and engine life, for buggerall extra cost per tank compared to the regular unleaded....

even with cars before my skyline, I have always used premium. I found that in my previous n/a cars it was actually cheaper (not by heaps, but definitely a difference) due to the extra kms I got from a tank. (plus there was a little more power and the engine seemed to run smoother). Couldn't comment on differences in fuel consumption with the skyline because I have never put anything but 98 octane in it.

100 octane 5% ethanol Shell V Power racing... car loves the stuff :D

how did you manage to afford the car, and not be able to afford the petrol??? mummas boy... or dad... whoever makes the money :cheers:

^^ i was tempted to try VP racing when I went past a shell that carried it but I figured it was so out of the way that it would only ever be 1 tankful and a) the engine would have to re-learn less ignition when I put 98RON back in and b) if I don't know what I'm missing it's not so bad :D

when it gets a bit more widespread I'll give it a go.

Seeing that we're on the topic of what type of petrol to use, what would happen if we were to put diesel fuel into our cars? :bunny:

try it and you'll be plesantly surprised

speaking of V racing, where do you guys get the stuff??? am I supposed to join some secret society for it?

how did you manage to afford the car, and not be able to afford the petrol??? mummas boy... or dad... whoever makes the money :P

lol thanks for that DRD-00F but i dont get any handouts and since i own an r33, and I have to run it on money from a safeway part time job. I thought i would be best off to get some ideas on what i should and shouldn't save money on. i think i will have to keep putting in the premium stuff. Maybe i also need to get my oxygen sensor tested as my fuel economy seems pretty crap at the moment

100 octane 5% ethanol Shell V Power racing... car loves the stuff :(

how did you manage to afford the car, and not be able to afford the petrol??? mummas boy... or dad... whoever makes the money :P

v power racing is the shit!!! my sprinter absolutely loves it. atm im running about 106 ron worth of 98 and octane booster and the little rice mobile loves it.

are we satisfied jeremy? as i said from the beginning if i have to run 98 in my sprinter then why wouldnt u have to run 98 in your skyline?

    • I know why it happened and I’m embarrassed to say but I was testing the polarity of one of the led bulb to see which side was positive with a 12v battery and that’s when it decided to fry hoping I didn’t damage anything else
    • I came here to note that is a zener diode too base on the info there. Based on that, I'd also be suspicious that replacing it, and it's likely to do the same. A lot of use cases will see it used as either voltage protection, or to create a cheap but relatively stable fixed voltage supply. That would mean it has seen more voltage than it should, and has gone into voltage melt down. If there is something else in the circuit dumping out higher than it should voltages, that needs to be found too. It's quite likely they're trying to use the Zener to limit the voltage that is hitting through to the transistor beside it, so what ever goes to the zener is likely a signal, and they're using the transistor in that circuit to amplify it. Especially as it seems they've also got a capacitor across the zener. Looks like there is meant to be something "noisy" to that zener, and what ever it was, had a melt down. Looking at that picture, it also looks like there's some solder joints that really need redoing, and it might be worth having the whole board properly inspected.  Unfortunately, without being able to stick a multimeter on it, and start tracing it all out, I'm pretty much at a loss now to help. I don't even believe I have a climate control board from an R33 around here to pull apart and see if any of the circuit appears similar to give some ideas.
    • Nah - but you won't find anything on dismantling the seats in any such thing anyway.
    • Could be. Could also be that they sit around broken more. To be fair, you almost never see one driving around. I see more R chassis GTRs than the Renault ones.
    • Yeah. Nah. This is why I said My bold for my double emphasis. We're not talking about cars tuned to the edge of det here. We're talking about normal cars. Flame propagation speed and the amount of energy required to ignite the fuel are not significant factors when running at 1500-4000 rpm, and medium to light loads, like nearly every car on the road (except twin cab utes which are driven at 6k and 100% load all the time). There is no shortage of ignition energy available in any petrol engine. If there was, we'd all be in deep shit. The calorific value, on a volume basis, is significantly different, between 98 and 91, and that turns up immediately in consumption numbers. You can see the signal easily if you control for the other variables well enough, and/or collect enough stats. As to not seeing any benefit - we had a couple of EF and EL Falcons in the company fleet back in the late 90s and early 2000s. The EEC IV ECU in those things was particularly good at adding in timing as soon as knock headroom improved, which typically came from putting in some 95 or 98. The responsiveness and power improved noticeably, and the fuel consumption dropped considerably, just from going to 95. Less delta from there to 98 - almost not noticeable, compared to the big differences seen between 91 and 95. Way back in the day, when supermarkets first started selling fuel from their own stations, I did thousands of km in FNQ in a small Toyota. I can't remember if it was a Starlet or an early Yaris. Anyway - the supermarket servos were bringing in cheap fuel from Indonesia, and the other servos were still using locally refined gear. The fuel consumption was typically at least 5%, often as much as 8% worse on the Indo shit, presumably because they had a lot more oxygenated component in the brew, and were probably barely meeting the octane spec. Around the same time or maybe a bit later (like 25 years ago), I could tell the difference between Shell 98 and BP 98, and typically preferred to only use Shell then because the Skyline ran so much better on it. Years later I found the realtionship between them had swapped, as a consequence of yet more refinery closures. So I've only used BP 98 since. Although, I must say that I could not fault the odd tank of United 98 that I've run. It's probably the same stuff. It is also very important to remember that these findings are often dependent on region. With most of the refineries in Oz now dead, there's less variability in local stuff, and he majority of our fuels are not even refined here any more anyway. It probably depends more on which SE Asian refinery is currently cheapest to operate.
