Poll:- Best 98 Octane PULP

[You Yangs]

Now that all the major fuel suppliers have a 98 octane fuel on the market I'd like know what everyone thoughts are on whatever fuel they use, including price,economy,power etc Cheers

BP Ultimate is by far the best, followed by Mobil Synergy 8000. I would never go back to Optimax after the constant pinging my engine has on this fuel. I have had the timing advanced to take 98 RON fuel only and Optimax is the only one I have had issues with.

[FordFan86]

I use vortex all the time... its only 96 here tho... 95 in some places (i work for caltex, south australia...)
but nah mates
whats wrong with da fooly shick ulp?!?

[Yellow Fire]

Voted everything except Optimax. My cars hate that crap.

[ilsautomotive]

Vortex 98 is a new product which I haven't had an opportunity to try yet. I usually use Mobil 8000 but I'll be damned if I can actually notice a difference from one fuel to the next.

[250 PURSUIT]

I use shell my wife works for them i love the discount i get and it runs great in my phoon.

[rodderz]

APS did an independant study on Vic fuels and found that Shell and Mobil were the most consistant out of the lot and had the highest true octane rating

I've heard that depending on where in Australia you are though, that different branded fuels may come from the same plant, depending on which company has the closest rig and facilities?

[FPV 41T]

I tried running optimax but had severe pinging at about 4800rpm so i put bp ultimate in
and now revs to 6000 without the slightest ping and gets better fuel economy synergy 8000 works good to.

[maverick]

I agree with D XR8, BP Ultimate and then Mobil. The Ultimate fuel was the only fuel to stop high rpm pinging in my TE50.

Having said that both BP & Mobil fuels seemed to be worse for fuel economy (on average) than Shell Optimax.

[whippet_zetec]

I use BP Ultimate, found my Focus runs alot smoother than with Optimax, dont use Mobil 8000 much and havent tried the Vortex 98. I also agree with "Maverick", my fuel consumption is a little higher with BP Ultimate than with Optimax.

[xdc351]

My XF has 10.5:1 comp and runs PULP. It absoloutly hated optimax, ran well on synergy 8000 but was a real bitch to deal with on cold mornings and pinged on 95 RON fuels.

Overall the Ultimate was more consistent, smoother and easier to run when cold. It gets my vote.

[Pilch]

I found the clevo pinged on 95RON, and since swapping over to BP Ulitmate it has run smoother, and with slight power increases. Don't care much about economy though!

[CAMS290]

Wont use optimax in my lawn mower, mostly i use Synergy 8000 and occasionaly Vortex, havent tried BP Ultimate yet, but most people so far on this poll rekons its good.....must give it a go

Rodderz thats true but these tests were only done in Melbourne and Sydney the results were Shell Optimax and Mobil Snergy were hard to split the BP ultimate was there last chioce..these are all 98 ron fuels...
Vortex is 96 ron at the moment but Caltex has started rolling it out to some servo's in a 98 ron...see there website for more info..

[The Mighty Red]

BP ultimate all the way ,the xr luvs the stuff , I use it in the my xc clevo ute aswell with octane booster added

i agree my motor is very sensitive to shit fuel and it pings its head off on optimax...bp is good but i got charged an extra 17 cent a litre more than normal unleaded the other night.

[Kenaz]

Synergy 8000 - It works well and I won a Mobil Synergy 8000 cap once from entering a competition. lol

[Thunder Kiss]

I only use Mobil Synergy 8000 after poor experiences with Optimax.

[Fairlane]

I found BP Ultimate to be the best PULP in QLD (won't touch Bp 91 octane). Optimax just doesn't seem quite as good and the economy suffers.

However when i went down to Newcastle a few months ago. I thought Synergy 8000 was of equal quality as Ultimate. Using it was quite a novely for me as I can't get Synergy 8000 or Vortex Gold.

[Sprint_ED]

when i was using optimax, that thing pinnged more than it did rev, but i feel that synergy and ultimate are far the best 2 fuels, have not tried vortex, i sometimes feel that ultmate, pingged in really hot days where mobil didnt

[Sourbastard]

I noticed an article in the Jan 2005 Street Machine about fuel especially for performance, heres the gist of the article.

Mike Campbell from TOCA did the testing, and this is apparently regarding street cars with 12:1 compression or less.

Bp Ultimate mixed with Nulon Pro Strength Octaine booster, mixed normally as per the instructions on the bottle, yielded the best results. On a 351 windsor, running avgas it made 500hp/410ft-lb. On the ultimate nulon brew it made 525hp/420ft-lb.

ofcourse this isnt as good as an oxygenated fuel like VP-SV05 which runs up to 17:1 compression, but its not as expensive either.

I'm going to try this at heathcote and see what happens. who knows, it might not be BS! lol

[pauljh74]

OK from another perspective - which fuel do you guys think is better at cleaning the fuel system - being EFI? My mechanic asked me to put Synergy 8000 in my EL XR6 every 2nd tank for a while - better to do this than put the injectors through a clean at $200+. Considering it's tuned for 91 RON, I don't see much importance in higher octane ratings for my case. I ran about 4 tanks of Optimax through it (so I could use the Coles discount dockets) and didn't feel any change. I read here about Optimax not being that good as well as a friend telling me that and I just gave it is first tank of Mobil Synergy 8000. Before - when it was cold, it used to hesitate a little on the first few openings of the throttle, but it hasn't done it on this tank at all.

I was using the Safeway fuel because I preferred to shop at Safeway, but my mechanic said the Safeway fuel had too much sodium in it and to stay away from it as it will clog up the injectors. He wasn't sure how many of the Safeway servos were now using Caltex fuel - so it may have improved.

[Hoops]

I use Vortex 98 in the Pursuit, seem to get better fuel economy out of it than the other fuels

[Dark Horse]

BP Ultimate here. The XR loves it, plus it's only 2 mins drive down the road to get it.

[rodderz]

Could it be the way you car is tuned also.... when you get an aftermarket chip or edit (custom tune) they tune your engine according to what fuel you currently had in it. My ute had synergy in it and seems to run best on that but i use optimax too, the missus does shopping at coles and you get the discount tokens!

I'll alternate between Vortex and Ultimate with no noticable difference between either.

[wrx365]

I use Optimax as there is definitely a noticable difference between it and the other brands. I have tried all and they all seem to be good. One thing I have noticed is that since the issues Shell had few weeks back with optimax were fixed, Optimax now seems to be much been better.

However interestingly with my new GT (only done 1000km) , I don't seem to notice any difference between Vortex premium unleaded (95RON) and Optimax and Ultimate (haven't tried the others).

BTW Vortex 95 has the same cleansing agents as Vortex 98 with the only difference being the octane rating. If you are forced or decide to use simple premium then Vortex seesm to be the best bet.

[Kev_BLNXR8_Ute]

I have to agree with the majority. I would say the BP seems to be the best how ever I do find myself using the shell a fair bit due to the cost of fuel and the 4 cent discount is hard to pass when it's like a $1.10 for premium.
Other than that if it is one of the main supplyers and everyone else has just jumped 10 cents while you at work the cheapest I come along will do just fine.

[Quasi]

When I bought my 5.0L EBII I used Shell, but have been using Vortex for a while now.

[svo347]

BP98 .. Anything else & it pings its head off.
