I am not sure about Ethanol. Some say that it is actually good for the car (small amounts) and some say that you don't need it and can be harmful to engine.

Does BP have ethanol in their petrol? I know Shell advertise that it doesn't contain any ethanol.

Way back before the dawn of time (I.E. Before SAU started and we were all in SDU) someone took the inititive to test all 3 fuels and in terms of the RON ratings they were all pretty close with no major winner between the 3 of them. BP was first, then Mobil 8000 then Optimax. All over the 98 RON mark.

What was more interesting was the chemical content within the fuels. I can't remember what contained what but Optimax had other additives and stuff. I think it was supposed to be a bad thing but don't quote me on that.

I've since tried to find the thread but it's gone to Thread Heaven... :P

However I feel that you should stick with what you think. All 3 aren't bad and it's not like your going to gain massive HP by running [insert fuel brand here]. People have had different experiences with all fuels some run better on this, others on that.

I use whatever I'm closest to when I need to fill up, but generally have gone for Optimax. Ive found through the 3 main ones that Ultimate seems to give me good fuel economy, where Mobil gives me good performance and Optimax is a combination. Like a good all-rounder... I have noticed that results on Optimax tend to vary from servo to servo sometimes, but if you find a good one stick with it.

Man BP Ultimate is pretty hard to find in my area!!

Drove into 2 BPs and one had premium unleaded and the other just had unleaded. Look like a fool driving in and driving off haha. I think I found one for sure now with BP Ultimate, but still haven't try it out yet.

i tryed bp and vortex and my car didnt like em at all

ive been told by many that these are the best and have highest octane etc

but for sum reason my line didnt take to it very well

ran much better with optimax

:confused:

I manage a caltex servo on the Gold Coast and it has the worst premium grade fuel I have used :D I never use Caltex Vortex it doesnt have the RON of the other brands... You can tell by the difference in price between the unleaded. Vortex is generally 5 cents dearer than unleaded at Caltex, BP ultimate is generally 8-10 cents dearer !!! I only run ultimate where possible, If I cant I use Optimax.... These two give better mileage which offset the extra cost.. Never really liked Mobile after all the deal with the aviation fuel getting diluted in our petrol so I havnt tried them! The other good thing to do is run Nulon petrol treatment.. by far the best. Its a red container.

    • 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.
