Use what the manual recommends.

Higher octane rating doesn't mean more power, it means the fuel is more resistant to being ignited. So putting like 98ron fuel and octane booster into an old R31 is just going to make your car a son of a bitch to get started and missfire or something.

I wouldn't bother wasting money on BP Ultimate with a normal car just because it has detergent in it.

There is a reason BP98 is the most recommended pump fuel for high performance cars...

and ????????

if you state that then you should state the reason

any 98 is better for a high performance car .

Ultimate offers no gains over Vortex 98 and vica-versa

I beg to differ. Reasons have been pointed out in this thread already.

Not all 98 fuel is the same. It may have 98 octane, but that is just the RON, there is more to fuel than that. My mechanic owns the Glen Forrest Caltex service station, he is highly into cars and is the only mechanic i trust my car with. I asked him what fuel i should be filling up with and he told me BP Ultimate hands down. That coming from the owner of a Caltex. Now I'm not basing my argument on that fact but it does still weigh in.

I've driven with other fuels before. Vortex i don't notice a difference in performance but i don't get the same mileage out of it as i do with Ultimate. I've tested this numerous times, and be it absolutely hammering my car taking it up to redline or driving like a old woman, BP Ultimate comes out on top everytime, i get about 15-20% better efficiency with it. Peak 98 is shocking, i'll never use that again. Car drove like crap and i only got 210km's out of a full tank. I've never used Shell in my car, refuse to touch the stuff after it destroyed my dad's old car.

Point is, you ask anyone that knows anything about fuel and cars, their recommendation is BP Ultimate. Sure it may be similar to other cheap fuels, but cheap Chinese performance parts are very similar to Japanese performance parts... Rule of thumb with cars, you get what you pay for.

I used peak about a week ago and got 425kms, how the hell did you manage 210kms in a non-turbo.

Hence why i don't like Peak. Went straight back to 500kms to a tank when i filled up with BP again. I wasn't driving aggressively or anything either. May have been a bad bit of fuel, i have no idea, but i've never had a problem with BP. For me it is tried and trusted. I've done my own comparisons and BP stands out. I'd rather pay the extra 5c p/L, or whatever the difference is at the time, for the piece of mind that what i'm putting in my car is healthy.

Why do you change fuels for in forst place ??

I also prefer to pay a premium for consistency in quality.

Wont ever be consistent in pump fuels

    • What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.
    • Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.
    • looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
