Which Petrol is better	Wed, 24 December 2003 16:04

okies guyz i have just finished reading a debate on a nissan forum about which Premium Unleaded Petrol is better for your car .... the arguement was pretty long and everyone seems to have different point of views ... some said that "Shell optimax" was good but alot of people disagreed and said that Optimax was the worst ... majority of the people said that "Mobil Synergy 8000" was to use with "BP Ultimate" being 2nd favourite ... now this got me wondering because i have been using "Shell Optimax" for quite sometime now and honestly i have tried different petrols and i seriously cant tell the difference ... so i decided to go with Optimax because i live near a Shell service station ... i currently have a Bigport 4AGE AE82 ... would anyone here know what would be the best PULP for this engine ??

Ultimate and Optimax are both 98RON , the only difference is that they advertise optimax cleans your engine. [Report message to a moderator]

Good, cos i use ultimate Although as i also have a ampol/caltex card, vortex gold is sometimes the only option :S. I saw a sign saying ampol was bringing out a new premium unleaded petrol? I presume it would be 98ron if vortex is 95, might have to give it a try when it comes out [Report message to a moderator]

It depends on what car you have, and how it is tuned. What car do you have, and are there any modifications? Even if not modified, the large majority of cars will benefit from running Optimax/Ultimate. I am in Brisbane so we don't have Synergy or that other one. Votex is available but it's rubbish, only 95 octane. Personal choice is BP Ultimate over Optimax but there's no real reason, I just prefer it. [Report message to a moderator]

ok guys lets sort out some things optimax and ultimate and mobil synergy etc are not premium unleaded fuels premium unleaded it 95 RON ultimate, optimax etc are 98 RON and u cant compare CALTEX vortex to other 98 ron fuels as vortex is a premium unleaded (95 RON) and yes its a better idea to get fuel at busy servo's as condensation over time will contaminate the fuel with water and from what ive gathered optimax is the worst 98 fuel u can get BP ultimate and Mobil synergy 8000 are the top.....and i can actually vouch that i do feel a difference on my bike with the mobil regular unleaded (91 RON) compared to other fuels.....but dunno about the 95 & 98 fuels....never tried oh also.....theres really fuk all point of running a higher RON thats spec'ed to your car unless u raise compression ratio really...thats if u wanna do things properly Ta Mani [Updated on: Fri, 26 December 2003 09:14] [Report message to a moderator]

Re: Which Petrol is better	Fri, 26 December 2003 10:34

Hey all, The only fuel I used is Optimax. My SA-63 has tried all the 98ron fuel. For some reason Optimax gets better fuel comsuption (9-10l/100km). With other fuel like Synergy and Ultimate the car burns more fuel (12-15L/100km) and Vortex burnt even more. I use to do more then 1000km per week for 2 months and I had experiemented all the 98ron petrol avaliable to try and maximise the economy for my 2S-C. All our cars use only optimax.

okies well i have just been using Ultimate for the last 2 days and i did feel abit of improvement on consumption ... i got about 1/5 more than Optimax and also the car feels more relaxed and smoother ... in 2 days i will try the Synergy and see how it goes ... by the way i am doing this expirament on an AE82 local bigport ... so i think it may vary depending on other cars ...

Use the fuel your car is designed/tuned for. I only use optimax as my car was specifically tuned to run on optimax. If you want to read up on another forum site http://www.lextreme.com/forum/viewtopic.php?t=527& amp;postdays=0&postorder=asc&start=15 there was a big discussion there on which fuel to use. Oh, and if you want more milage and better throttle response etc. - do an oil & filter change! [Report message to a moderator]

exactly what pete said however i dont agree with the method of advancing ignition timing to raise compression but hey its a start and also if u want to test out a fuel to see how well your car runs ....u have to use it for a few tanks so your computer can tune to it....THEN u can test it out and by tune ...all it pretty much does it advance ignition timing Ta Mani [Report message to a moderator]

Use the fuel your car is designed/tuned for. Rubbish. YOu will notice that MANY standard cars ping as they drive past. A better quality fuel will improve this no end, despite the car being 'tuned' for standard fuel. Octane is effectively the resistance to knock and therefore will benefit any car that suffers from detonation. [Report message to a moderator]

Re: Which Petrol is better	Sun, 28 December 2003 00:24

7M: Who here drives a "standard" car?? If your car is pinging then theres probably other reasons, but sure I agree that a higher octane fuel would reduce it. Run premium if your car is pinging, untill you can get it fixed properly. Standard, well serviced cars won't ping on regular fuel. "Better quality fuel" is relative. Premium is better for a standard car, but if you start running even better quality fuels like methanol etc. you'll blow something pretty quick as they're not designed to do it. What I thought this thread was about was which was better of the higher grade fuels (not between regular and premium). Mani, I'll go one further, and say if your testing other fuels reset your computer (unplug it for a few minutes) so the computer can learn fresh. Again though, do this with your regular fuel first so you can compare it properly. [Report message to a moderator]

Re: Which Petrol is better	Sun, 28 December 2003 00:35

I like the idea of running Methanol/Ethanol in cars. It's higher octane, doesn't need additives to make it burn more evenly (or rather, IS the additive) like petrol does. It also doesn't impact the environment nearly as badly. What I wanna know is why there is such a fuss over here about Ethanol in fuel over here? In America, they have E85 (85% Ethanol, 15% Petroleum) and cars that can use E85, normal Petrol, or a mix of the two. And that stuff is something like… 125 octane? Something like that. Although they say you shouldn’t upgrade a car to run on ethanol I’m sure it can be done. New fuel lines, new petrol tank, a fuel mix sensor, new fuel injectors, appropriate computer upgrades and modifications and most modern cars could run on E85. Stupid Australian Govornment.

Ethanol has been proven to fuck up engines and as such, voids warranties if it's found to be used in engines... Thats why we don't like it... I use Mobil unleaded... I didn't notice anything between Mobil 8000 and normal unleaded except the price... The car ran the same... But as soon as i get it running like it should, then I'll give 8000 a try again and see if I can feel the difference... Or maybe see the difference when the fuel guage drops less over time ... It's running 300kms to a tank at the moment... So I ain't wasting all that 8000 and money... [Report message to a moderator]

Well after using Optimax exclusively for 20,000km my injectors needed to be sonically clean again. Other people have had other gripes about Optimax on this forum in the past. When I spoke with a Toyota parts person he reckoned the spark plugs on his bike kept fouling up using Optimax. But he doesn't have this problem with the Mobil 8000 or BP Ultimate. His preference was with the Mobil 8000 so that was what I ended up sticking with. [Updated on: Sun, 28 December 2003 10:38] [Report message to a moderator]

Well i better not get in to this discussion, as i work at a BP. All i have to say is yes Ultimate is better than the Premium Unleaded that is supplied by BP, it is still sold at several petrol stations(yes we are petrol stations not service stations, if u want a service station find a mechanic that sell petrol). I will not comment on the pricing as i am not allowed to talk about it, so don't ask. [Report message to a moderator]

Dont F1 cars run Ethanol or Methanol? I agree that you need a car that is designed to run on E85. My point is America has them, we do not. There is a South American country that has a lot of cars running on part ethanol petrol too... I forget what country it is. P.S. Oh yeah, and Ethanol was investigated as an additive for fuel to increase the Octane, but they decided to go with lead instead 'cuz oil companies didn't want to give away such a large proportion of their money to agriculture, or something like that. Ethanol isn't evil, and 10% Ethanol is apparently better for your engine than premium unleaded, but my sources on that last bit aren't as solid as I would like them to be.

From my undestanding there is nothing wrong with ethanol in regards to emissions or any thing like that, and the fact that they use it extensivly in the US means It won't be long before it gets accepted over here. The problem here is car's fuel lines aren't designed for the stuff and deteriorate. And then the media blew it out of proportion. [Report message to a moderator]

New cars should be re-tuned to take more than 10% Ethanol, apparently. According to a recent study by the Fedoral Govornment 10% Ethanol does not harm old or new engiens. The study seems to have discovered that more than 10% can harm older engines, while they are still trying to figure out what percentage newer cars can handle. "...all major manufacturers, have indicated that they are quite prepared to warrant the performance of their engines with the ten per cent blends." Read this on the new 10% Ethanol Cap. And this on why the cap is bad. It's shows like Today Tonight that screw it all up for everyone. Every time I see a news report on Today Tonight or a Current Affair, I instantly think that it must be a lie. P.S. I am personally against a 10% limit on all fuels. I think the limit should be more complicated than that. I think that petrol stations should have to offer a standard petrol, that has a limit of 10% (if that's Premium or just normal unleaded). But petrol stations should be able to offer an E85 option if they wish.. While this doesn't effect the market at the moment, in a few years time we may see some cars that can run E85 hitting the market if there is an infrastructure for them.

My car also runs worse when running optimax, the car feels a lot more sluggish like its choking with optimax. I normally use vortex gold cause i have a caltex near by and it gives me the best response where the engine runs smoother throughout the revs. Shell optimax is also crap on my motorbike, it really feels like the engine is chocking then i put in vortex and its like a new motorbike reving smoothly to 18,000 rpm, i found out shell optimax fouls up most motorbike's spark plugs and there was a media release warning motorbike owners on using optimax. I will have to try BP & Mobil and see how i go. Smile

FROM WRX FORUMS

Vortex is 95 RON not 96 as someone stated..
Vortex does NOT have Ethanol in is nore does any of CALTEX fuels and it does on the pumps say these words.

CALTEX FUELS CONTAINS NO ETHANOL AND IS 100% CALTEX CONTROLED

Vortex WILL be in 98 RON in the next six months

I know this as i own a CALTEX x3

As for the 03 WRX well unfortunatley Caltex is not upto the Subaru requiremnets as its not enough octane but will not hurt it if only a couple of tanks were used.. 02 WRX and before unless you have aftermarket ECUs there is no benefit of using a higher octane fuel.. we have done many a tests on this and proven it will do nothing for the power of the car... Most people will notice a more responsive and smoother driving but that has nothing to do with the OCTANE rating. more to do with the addtives added to the fuel..

i have an 02 WRX making 170+ kw@wheels and use VORTEX with no problems.. next month i will be getting it retuned as i have put a GT400 turbo (previously had a VF22) so i am hoping for over 180kw@4wheels and still will be tuned with VORTEX 95 RON fuel

Dont be fooled by OCTANE ratings.. Power and drivablilty has more to do with the make up of the fuel rather then OCTANE.. Shell has done a great job in making people believe OCTANE is the be all of power

This had been brought up a few times on these forums (and the old ones) so do a search, there were some really, really educated responses (ie: from chemical engineers who'd analysed the fuels and engine builders who'd stripped down engines running on them). From what I remember was that BP Ultimate was the best with Mobil Synergy a close second. Shell Optimax left residues inside the engines and also didn't keep its octane as well as the others. On the flip side, Optimax is everywhere and now you can get 4c/L off using Coles dockets. As for using higher octane fuels, only look for power increases if your car is tuned to use the fuel.

Re: Which Petrol is better	Thu, 01 January 2004 15:28

What about normal Shell Petrol? This may just be my imagination, but I chucked some shell unleaded in my Lancer and noticed the car seemed "unhappy" (could have just been hot weather also). Anyway, then when it got low again, I chucked in some BP Ultimate. Right away the car got happy again. It feels more powerful low in the revs (not so much up high) and I have DEFINITELY noticed that a bubbling kind of sound I always used to get when opening the throttle all the way down low in the revs has gone away completely now. I'm gonna keep a close eye on performance and fuel consumption, then try some other petrols once this tank is empty, including some different low Octane fuels and see if the bubbling sound comes back and stuff.

as a VERY generalised statement, ive noticed that burbling sound through the exhaust indicates a rich mix [Report message to a moderator]

Happy new year all! The Octane rating is what you all need to check out before puting any fuel into your car nowdays. normal unleaded 91 LRP 93-95 Premium-95-98 I have noticed that BP has the lowest octane premium at only 95. A rip off at the same price as 98 elswhere. Caltex, shell(optimax) and Ampol are 98. The higher the octane the less pinging you get, better power and economy. I will only run my MA61 on Premium or LRP. I always rip into my girl if she puts ULP in her TX5. ant [Report message to a moderator]

I thought "Premium" was all 95 Octane. And that anything higher than that isn't called Premium. ie, BP Ultimate, Mobil Synergy 8000, Shell Optimax. [Report message to a moderator]
