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?

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
