I'm going to fill up with BP ultimate this week and give it a try.

Usually use shell but can't seem to find the difference between their 98 , 95 and 91.

The week after will give mobil a try and see.

I know this has been covered like a million times but give us yur thoughts on Mobil,Shell, BP and Caltex.

Which one do you find best when it comes to the 98 RON and which one is better in the 91RON.

Would like to hear from those who have knock sensors

cheers

Go to Freedom and get the E10 Fuel, its 95 octane which is higher then regular unleaded and is CHEAPER yes cheaper then the Regular Unleaded, or atleast in Brisbane it is!

Unless your tuned for a Higher Octane fuel
you wont notice any difference thoughout the whole range mate...

Stick with a higher octane though, as its cleaner and wont kill you injecters as quick.

fuel price is going up so if you want to do so, do it now.

Try those Magnetic Fuel savers on ebay for $30, i personally don't think they would work or the manufacturers would make them come with the cars or "built in" somehow.

BUT..... yes there is a but!
My mate has two and he swears it has reduced his fuel by about 20%, also the thousands of good feedback on ebay is a +

Dont know if it is my imagination or not, but I certainly notice a difference with Shell Optimax. The car has a little more get-up-and-go and feels much smoother. I usually get more kms out of a tank but probably doesnt compensate the extra 10 cents a litre.

Hi there,

Shell Optimax has a higher density which is how they claim that it goes further on a tank of gas. Never run it in anything with a carburettor, the motorcycle crowd steer clear of it. In the bike I like to run BP Ultimate 98. If that isnt available then it's Caltex vortex for me.

if they were so good every car would have them from factory

I am so sick of posts regarding the fuels... DO A SEARCH PEOPLE!!!!

Caltex Vortex seemed to work wonders on my old car which was a KS Verada. The mileage seemed to really stretch out. I

I've got a KH Verada now, and on my last tankful of Optimax, I'm sitting on 554km right now, with still 1/8th of a tank to go. Will probably crack 600km

Haven't tried BP Ultimate or Vortex yet......will keep you posted.

Premium fuels in 3rd gens makes absolutely no difference at all. Anything you THINK is different isn't. There's no knock sensors, so the timing doesn't advance itself to make use of the higher octane level in the fuel, so unless your car is tuned for it it won't make a difference to either power, or distance off your tank. The only reason to run premium fuel (unless your engine is tuned for it or you own a second gen magna) is for its cleaning abilities. Personally I used to put in Shell Optimax and got 500-550kms per tank, then I switched to regular unleaded and got 500-550kms per tank. Power and smoothness of the car is exactly the same. IMO, optimax and similair fuels are a dead set RIP OFF.

So true, don't bother with premium in a 3rd gen the only good thing it does is clean the motor and E10 does a better job of that for less $$

if they were so good every car would have them from factory

It would have a lot to do with patents and product licencing to get it into new cars from the factory.

Seeing as I get about 600km off a tank of Optimax and only 520-550km (sometimes lucky to crack 500) from regular....as well as a much smoother engine....there is a difference (for me). I have tried it out and made comparisons several times.

Unless you have sat your car on a dyno, with the EXACT same weather conditions, rev's, speed, tyre pressure, fuel amount, brand new fuel filter and a service for each of your fuels you have used, and km's traveled

You cannot compare the 2.

no, fuel isn't ferrous, magnets only affect iron, so he's bsing

i work my part time job at bp and most of the ultimate sells to the sportier cars and bikes, as well as some ppl like to use it in their boats. Have tried in my car no diff, no knock sensor :P

I'm sure more used it when petrol was cheaper, but now its getting a bit much.

Does anyone know why Mitsubishi decided to have knock sensors in the second gen and then take them away for the third gen? Are you able to install them on third gens?

Thanks

Dave

I use optimax extreme only.

The main difference I notice is more milage - it feels as if the acceleration is improved as well. Cant prove that, though.

i reckon bp ulitmate gives better throttle response then regular, plus i think its also wiser to get the higher octane rating for economical, pollution and care of engine

Good question. Can we take knock sensors off the 2nd Gen and fit them in a 3rd Gen???

Its not just coincidence that I get better performance and mileage from a tank of optimax compared to regular. I may not have figures to back it up...but there is defiently a difference. May not be for you or other people but is for me.

Well i'm sorry, but you are dead set dillusional. But have fun spending that extra 10c per litre on fuel. lol

BP 98 rons the best and does make a difference in performcane and fuel econamy. And works out cheaper than STANDARD CRAPY UNLEADED in the long run

Haha, cruel. :cry:

another one of these threads...:doubt:

why is everyone so opinionated about this topic?? who friggin cares... if i want to put bp ultimate or whatever in my car, then so be it... so people put it for the cleanliness, others for the benefits of higher octane fuel (ie, reduced pinging, etc) but if you choose not to put high ocatane fuel in, then why force it upon others? this is kinda like my mates who hate mitsu and think that every car they make is rubbish, then i cop it for owning a mitsu... yet i dont give them **** for driving fords around :confused: each to their own

having said that, i run bp ultimate in my carby fed car (look no knock sensor!! OHH NO! :bowrofl:), i've manually advanced the timing way out of mitsu's specs, and enjoying a little bit more power and economy (if i stop having a heavy right foot) and also, it does not ping on hot days - after running normal ULP for a while with stocko timing, eventually my motor starts to ping on hot days labouring up a hill with airconditioner on... after a few tanks of premo, advance the timing a little by a few degrees (i want the motor to efficiently use the fuel), and the pinging is gone.

so bottom line: i use premo cos there seems to be less carbon build up (only reason i can think of why the pinging gradually comes back - it's ever so slight though when it does), bit more response in the throttle (after advancing timing manually), and also on hot days, i dont get vapour lock, smell of petrol, stalling, etc - all the quirks related to owning a carby.

especially when trying to turn right, your about to go... you press the go pedal... and it stalls halfway through the turn, then you smell petrol while your frantically try to start the car before someone smashes into you... but luckly they slow down, the car eventually starts and you take off quick... that's reason enough for me to put premo in my car alone. i've had a few close calls with the car stalling on stinking hot days... and with ULP i can jsut smell petrol all the time too on hot days - comes through the airconditioner vents.

and yes i've had my carby rebuild, all fuel lines replaced, new fuel pump, filter, check the metal fuel lines... there is no leaks... i cannot seem to solve the problem, but premo is the work around

/end rant

/thread too

Thanks for all the replies. Filled her up with 65L BP Ultimate @$127.9c/L. Will see if i've wasted the money or not.

used all 3 types of fuels over the last 6 years with 3 different cars:

1. KJIII laser 99 model 1.8l DOHC. 52 litre fuel tank, 92RON v's 98 RON (no 95 yet) 98 RON = 8-10cents per litre more, but 150 kms extra milage on average.

2. Holden/Opel Calibra 92 model 2.0l DOHC, 61 litre tank.
designed to run on RON 95, reg 92 = poor performance and 450kms a tank. RON 95 = good performance and up to 700kms a tank and only 4c more per litre at independant stations. 98 RON, tried optimax and Mobile 8000 with little difference, and with a car designed to run on higher octane fuel, i was very disapointed to see it ran on a lower economy than the regular 95 (at most 620 on 98).

3. My magna 3.0 TE. run it on reg 92 RON 1st 2 fills and got 643km out of 54 litres 1st, 527lt out of 527km (?)
last fill, 95 RON from independant servo 680km from 578lt .

most of the driving of all 3 cars was over highways with some city traffic, thats my averages over the whole range of driving with my driving being rather aggressive as well. i dont live in a capitol city so the fuel economy of inner city driving is lost on me most of the times.

Personally i would suggest using RON 95 premium as i feel its more value for money, use the 98 for the cleaning properties, but i dont see any reason to use it all the time.

You need to :gtfo: :slap:
He asked for opinions, and he got them, as he has also thanked people for them.

If you can not handle opinion based threads, you need to get off the internet, and go play with you barbie dolls.

You guys do realise that there are more fuel brands than there are actual oil refineries in Australia right?

For instance, in Sydney, Optimax comes from Shell (duh!) but BP Ultimate, Caltex Vortex and Mobil 8000 all come from the same vat of fuel from Caltex. Apparently the fuel trucks just drive to the vat, hop out, and hit a button for which particular fuel their supposed to be carrying - so some non petrolium additives may be added, but probably make little difference in the big scheme of things.

sure he asked for opinions, and that is fine... but others have also given their opinions and stated that they notice and feel a difference running different fuels reguardless of wether or not their car is tuned for it. As soon as someone says "i got 50km more and a responsive throttle" everyone is very quick to state their opinions about their car not being tuned for fuel, waste of money, etc... do you get what i mean?

i respect other peoples opinions, and i do believe that theoretically a high octane fuel is not gonna do anything in a N/A motor unless even something as simple as timing is changed, but i also take onboard what other's experiences are with it.

at the same time, while people also say they feel it to be more "powerful" no one actually has proof...

no hard feelings ice_magik, it just seems to be the same story everytime with these kind of threads, that's all.

bottom line: sure, state that different fuel doesn't make any difference, but when someone else states that they noticed a difference, then dont rubbish that by stating your opinion again.

Also, cos it's been covered so many times, use the search!

and will someone out there get some definitive results about power output with different fuels :)

Cheers,
Bill

maybe there should be a stickied thread or something in the 3rd gen faqs for fuel usage/consumption which we could refer new users to in order to answer their questions?????? :boohoo:

For instance, in Sydney, Optimax comes from Shell (duh!) but BP Ultimate, Caltex Vortex and Mobil 8000 all come from the same vat of fuel from Caltex. .

You're kidding right?

BP have 2 of their own refineries in WA and QLD

Mobil have their own refinery in Altona Vic (and had one in Adelaide until it closed a few years agao).

Caltex have refineries in QLD and NSW.

maybe there should be a stickied thread or something in the 3rd gen faqs for fuel usage/consumption which we could refer new users to in order to answer their questions?????? :boohoo:

I second that, how many times have we started a new thread on fuel consumption? Why not just have one section thread on fuel?
All fuel saving products, all performance fuel products, filters, petrol cleaners can just dump into that section for your answers to fuel regarding topics.

Regarding higher octane, you do feel a difference, but whether is worth your pocket is another topic. Yes if you are tune for it, is better, obviously. Someone who is rich will not care about the fuel price will pump with best grade regardless, so dont go argueing about tune or not tune for it. Let them have a say if they want to. Even if its slight difference I say is different. I do not have the welfare to pump such fuel, but if I could I would. In which I did not vote.

BP Ultimate for me. I feel a slight bit more power. I dont know.. I use it from time ta time. Im not saying i run my car on BP Ultimate all year...might fill up with BP Ultimate once a month.


Dyno's have been done etc etc.. it does yeld more power but we are only talking about a few Kw

Every fuel pump is different

Shell optimax, Caltex Vortex, BP Ultimate etc. all have what are called priority stores (Working for coles I know this very well :()

Priority stores usually receive the highest grade of petrol. Medium and small stores receive the standard grade, and can quite often receive bad batches. It doesn't matter where you go, Fuel is fuel. The only thing that sets one fuel apart from another, are the impurities in the fuel. Again BP, Shell, Caltex, Mobil etc. all have to sell fuel, and can't control the quality 100%. You just have to get lucky and find the priority stores and hope for the best :)

98 Octane = 98 Octane

Also 98 is useless in a magna unless u've tuned it for 98 (as said earlier)

91/92 tend to contain impurities causing deposits through out the fuel system (I reccomend using a total fuel system cleaner [nulon products are quite good] once every 3-6 months)

95 Is a good balance - Not to expensive, but not as many impurities (USUALLY, not always going to be the case)



I am so sick of posts regarding the fuels... DO A SEARCH PEOPLE!!!!

So? Search function = ****
The world is also constantly changing on a week to week basis? Secondly not everything gets 100% discussed as it is impossible. Someone is gonna come along one day with new information and someones gonna crack the ****s and tell them to search, and there goes the research out the window all because you assumed the post has been repeated millions of time with EXACTLY the same content.

e.g. My question about the metal brackets in my GF's magna for 6x9's, wasn't in the FAQ, wasn't in the forums, yet I got told to read the FAQ.

Understandable for fuel issues, it's raised over and over again, big deal? You'll get used to it :)

Anyway thats my 2ø, Just sick of seeing do a search in posts

Magnas are designed for normal unleaded, you will not see any difference unless you have power modded the engine or supercharged it. You have the same car as me, they are tuned for normal unleaded petrol.

I don't know how many times people have to be told there is no performance increase in a 3rd gen magna by using 98-100 premium :rant: However its still better fuel and if you can afford to use it, do so i mean it cleans the motor and will probly make it last longer anywhay!

I always go for Ethanol 10% fuel, its 95 octane so slightly cleaner/better thenr regular unleaded and its the CHEAPEST fuel, your nuts not to use it :)

So you saying that we should post something up each week, just cause minor/no changes are being made? Fuel doesn't change dude. And it has been discussed hundreds of times before on what difference each fuel makes. If people dont have anything new/usefull to post up about, then dont post and do research on your own. Then when you have a conclusive result, then report it... That's all im saying... do research before asking/reporting something that's been done so many times.

If people used the search tool more, you wouldn't be sick of seeing the Use the search tool comment. Hell, we wouldn't have to say it then.. would we?
