Vortex 98

[dangerous_daveo]

I've noticed its been out at pretty much every caltex servo.

On some info (proper testing) I read a while ago the vortex 98 was by far and away the better fuel to use. But as also noted on the testing is that not all fuel is made in the state its sold in. So I guess transport delays, longer in the heat etc could affect its performance.

So the question is, has anyone tried it. Is it any better than ultimate or optimax?

[AlexR34]

Ive tried it in my 1998 Nissan Skyline r34 Non Turbo, i usually put just plain vortex 95 cause the car doesnt require more. Ive also tried optimax and bp ultimate. For me i felt the greatest pull with vortex 98 but the petrol wasted the fastest over a weeks persiod. The BP Ultimate lasted the longest in the car but i felt no difference between that and plain vortex. Optimax 98 out lasted all the fules in the car but again no difference from the plain vortex.

Thats Just my experience in my NA.

tried it in the gtr, seems to be the same as the others so far

Agreed I felt no difference in the R32 (Power FC tuned on Ultimate) And in the R33 (Stock computer) I seemed to get slightly better fuel consumption than I did with ultimate

[Rhinorebel]

Bah!!! Shell Optimax EXTREME FTW!!!!!!!

Who cares if the promised cheaper prices for ethanol blends has never eventuated!!! 100 octane!!

[Silver_R34_GT-T]

Shell Optimax is the best And shell is normally cheaper than the BP fuel.. well thats just my experience from the stations i pass.

YEP OPTIMAX EXTREME FTW 100 octane....great there is a 100 octane pump fuel now without having to get bloudy avgas or actual race fuel.

[Silver_R34_GT-T]

is there really any difference in performance? between 98 and 100?

[Stephen22]

not that much unless you have a hard tuned engine

[mad082]

the theory is that bp ultimate has a minimum octane of 98ron, whereas shell and vortex98 (not 100% sure on vortex) are an average of 98ron.

in reality the difference between ultimate, vortex98 and optimax isn't much. what happens is that if a fuel company doesn't have a refinery in a state, then they will buy fuel off another company and pass it off as their own.

so if BP was the only fuel refinery in qld, then both votex98 and optimax would be the same as ultimate. it works out cheaper for shell and castrol than shipping it in from another state.

just don't buy vortex98 from woolies servo's, cause it may not be actual 98 ron fuel.

but i personally use ultimate, but i know guys that use vortex98 and have no problems. i use ultimate because a mate was a mechanic for repco and the nulon rep came though 1 day with a ron tester and he got some fuel out of my mates car to do tests with octane booster. it was ultimate and without octane booster it was 98.3ron.

for those interested, with nulon pro strength octane booster at reccomended strength it went up to 103ron. with it at twice the recommended strength it dropped to 97.2ron.

I find all full too expensive when you only get 250km;s to a tank...

Damn it...

[chances]

Ive been using vortex98 in my 32 gtr since it come to the servo down the road which was when it 1st come out and i noticed alot compared to the others and bp ultimate which was what i was using...

It would idle heaps nicer with the vortex98 over any of the other fuels and thats what kinda sold me cause i noticed it straight away, was like it cleaned out the crap that was in the lines or filter ?? i dunno ...

and it seem to rev nice all the way up to redline-ish

Whereas the shell 100 was pretty dogey i thought, rev'd a bit yuk, like it wouldnt be smooth at all and didnt like to be above 7 grand ... i might try it again sometime but i been using the vortex98 for like 5 months and i think its the best out of the lot anyway.

[dangerous_daveo]

Well I tried it. But it is 12c more than normal petrol where as the ultimate is 10c more... So unless I get something like 700kms to the tank I dont know if I can justify the extra expence. (got 658kms to the last tank, and have a photo to prove it )

I no the felling i only get 250/300km,s to a tank.

And if i nana it i will get about 350km,s

Not all of us drive with our eyes fixed on the boost guage and backing off at the slightest sign of boost

But the question that really needs to be asked. Is the 'extra' ~$8 per tank really matter that much? Seeing as we pay ~$80 per tank anyhow.

It really makes me laugh when theres a 3c difference between servo's and people go on about how they always try and find the cheaper one, when at the end it only makes a couple of bucks difference

unless they are across the road from each other there is no point hunting down the best fuel unless you pass them all on the way to work and can see which 1 is cheapest and stop there on the way home.

if you get 300kms per 50L, then you do an average of 6km per litre. so if the first servo was $1.38 per litre you go hunting for a better servo and drive more than 3.33km (6.66km round trip) to save 3 cents, then you will end up spending more money that you saved.

Yeah, see I drive past both anyway. So the 2c saving isnt actually going to cost me more. But if its not a better quality product and just the same then Im not paying 2c extra for it.

And just for the record Shane I dont drive off boost all the time. I drive so the car isnt straining, I also drive gateway traffic each day, so its not like its all 2am highway stuff. I found making the car work less by making it sometimes work more uses less petrol. 660kms compaired to 400kms that does make a big difference at the end of the year.

[nismo33]

actually they did an article on Autosalon magazine about these hi octane fuel ages ago and they tested BP / SHELL and Caltex and they find out that Caltex Vortex has about 98.5 while the rest are only 98ron.

but either way,.. they all work equally the same for me...although i use Vortex more often.

on a full tank of the stuff it feels great but once it hits the half tank mark it starts to fell sluggish - but in general its not too bad
