Hi

I'm getting my car dyno tuned very shortly and the mechanic asked me what fuel i usually run. I said optimax. He said that they tested fuels and for the best tuning results it was.

1. Ultimate

2. Synergy 8000

3. Optimax.

Now i've done a little searching around on the net and it seems that it's a fight between Synergy and Ultimate for the best tuning performance.

Now to be vehicle specific with skylines... Can any1 post what they've had their car tuned to and what their mechanic said about tuning with certain fuels.

Cheers,

On 3 occaisions I have used Optimax and during all three my car ran like shit, It also caused my cat to stuff up.

I have used Ultimate and it seems great, although I always used Synergy without a doubt as its always been great with my car.

Yeah thats probably the same order I'd use them as well. Ultimate is probably more difficult to locate but only optimax if I cant find the other two

I always run Ultimate but will settle for Synergy 8000 if that's all I can find.

Optimax has given me less than good results. It's a shame though because it's easy to find where I live but I have to drive 5k's to get Ultimate :cheers:

I have found Ultimate to be the best out of the

Ultimate vs Optimax battle..

I was once informed that Optimax is 'Up to 98 ron'

where as Ultimate 'Is 98 ron'

Anyway my advice is, pick a petrol and stick to it .. dont keep changing fuels or alternating between synergy and ultimate.

I have also found...

shit.. i forgot what i was going to say :cheers:

Currently using Synergy8000, was usung optimax for ages.....noticed the fumes (exhaust) did actually smell more, an the synergy8000 runs cleaner. Not really fussed between Mobil or BP 98 fuels, both seem to be a good product. But like most, only opt for Shell when have to.

Never had any experience with synergy, but I have talked to a couple of people in the know and basically what I was told was that Ultimate is refined to get 98 ron and Optimax just uses additives to get 98 ron. For this reason the Optimax will lose ron faster then Ultimate.

Everything I have read on public forums indicates the ultimate fuel to be the superior product.

But for some reason I get a noticeable improvement in fuel economy with optimax. Approx. 1-1.5km/L better.

I have seen many people mention the arguments about the optimax being "up to 98ron" and that it has additives to raise the ron level and ultimate is refined to 98 ron.

Does anybody have any documentation or links on the web to support these claims?

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.

      What ECU are you running? This is probably the biggest question. If it's a PowerFC, I'd probably change the ECU and get something newer that will handle the injectors in a nicer way.
