Has anyone used Shell 100 octane 'race fuel' as they call it? Just want to hear some of your feedback about it and how it is.

It contains 5% ethanol is this good or bad? I used it and the car was running pretty good but i dont know if there was a difference between normal 98 octane optimax or ultimate.. (and for you mobil people synergy 8000)

You mean V-Power Racing? It's the only fuel I use in my R33. It seems to run the best with it.

EDIT: There is a difference between V-Power & V-Power Racing. The former being 98 RON and the latter 100 RON.

V-Power racing is not available at all Shell stations.

I used to use it in my car, it caused my check engine light to come on a few times and i got 40 less kms out of a full tank.

That was when it first came out, it might be different now. BP ultimate rocks (not trying to start a fuel war thread lol)

Without going into it too much as we've discussed this many times over... IMO, I think Shell's V-Power is the absolute best... I get more milage, less ping and more bursts of power....

the shell v-power raceing (100 octane) was good im my 31 even being lightly moded still noticed a diffrence.

its good use it just rember it cost more.

V-Power Racing is the best fuel i have used....

do not worry about the ethanol, for any corrosion to take effect, it wil need at least 5-8years. by then your have to rebuild your engine any way....

i use it, brings my knock down to under 10 in hot days...high octane fuel FTW

the only problem is it is not available at too many places

and the nozzle of the pump sucks!

pisses me off how wa gets none of this shit!

by shit i mean good shit!

ha ha ha. i feel ya frustration and fair enough too. geographical locations, plays a big part of marketing unfortunately.

having said that, unless you have very well-tuned skyline with a lot of performance modifications, with V-power fuel you still wouldn't feel such a difference unless you really hammer it.

this is my personal experience, I've tried Optimax 98, Ultimate (with also 98% octaine), V-Power and a few more too; but i have to say, if you're just cruising a long, then anything with 98% octane would do the job and you would feel the extra juice, however, with V-power i noticed that the difference isn't too substantial unless you really push the car to its potential. one time my friend and i took our cars to caulder park, did some quarter-mile times and because i was literally 'flooring' it, at the peak i did feel a slight boost in power due to the V-power fuel. not bad i must say. but then again it does cost much more than usual fuel though.

so yeah, that's just my thoughts on it. i'm sure others will have their opinions too.

cheers,

But we import car drivers have to use 98+ octane anyway. So you can't compare to 92-95 when we can't use it anyway.

Also, V-Power Racing is just as expensive (or a little more) than the Mobil & BP stuff. Eitherway, the BP & Mobil 98 made my car start to stall. V-Power, not one problem.

octane is not measured in percentage is a rating number. also to get the full effect of a higher octane fuel u should get the timing adjusted accordingly usually advanced a degree or so. also with the ethanol content i wouldn't worry so much about the corrosion but more so the fact that ethanol leans out your a/f's only slightly but if an engine is tuned on the 'edge' then this could kill it.

I have done some work for a EFI manufactor in the past and they did tests using ethanol. Its not to good. It is corrosive!

They had stuffed injectors and all sorts. I got told to stay a way from it.

It is made using sugar, which if enough gets in your fuel tank can destroy a motor. One of the old revenge tricks was adding sugar to someones tank.

I don't usually go in for all the "this fuel is better than that one" BS, but I moved not long ago and now the closest servo to me is a Shell. I've gone through 2 tanks of the V-Power (98 octane) and I've noticed that my pinging and timing are way better then when I ran it exclusively on BP Ultimate

    • Can perhaps see how the R33 appreciators would think so.  
    • Thanks, I removed the fuse and the relay from the car and made my own circuit with them to test them with a test bulb.  I will look for the wiring diagram and go from there.
    • Jdm DC2R is also nice for a FF car compared to the regular hatches of the time.
    • Now that the break-in period for both clutch and transmission is nearly over I'd like to give some tips before I forget about everything that happened, also for anyone searching up how to do this job in the future: You will need at least 6 ton jack stands at full extension. I would go as far as to say maybe consider 12 ton jack stands because the height of the transmission + the Harbor Freight hydraulic platform-style transmission jack was enough that it was an absolute PITA getting the transmission out from under the car and back in. The top edge of the bellhousing wants to contact the subframe and oil pan and if you're doing this on the floor forget about trying to lift this transmission off the ground and onto a transmission jack from under the car. Also do not try to use a scissor jack transmission lift. You have to rotate the damn thing in-place on the transmission jack which is hard enough with an adjustable platform and a transmission cradle that will mostly keep the transmission from rolling off the jack but on a scissor lift with a tiny non-adjustable platform? Forget it. Use penetrating oil on the driveshaft bolts. I highly recommend getting a thin 6 point combination (box end + open end) wrench for both the rear driveshaft and front driveshaft and a wrench extension. These bolts are on tight with very little space to work with and those two things together made a massive difference. Even a high torque impact wrench is just the wrong tool for the job here and didn't do what I needed it to do. If your starter bolts aren't seized in place for whatever reason you can in fact snake in a 3/8 inch ratchet + 6 point standard chrome socket up in there and "just" remove the bolts for the starter. Or at least I could. It is entirely by feel, you can barely fit it in, you can barely turn the stupid ratchet, but it is possible. Pull the front pipe/downpipe before you attempt to remove the transmission. In theory you don't have to, in practice just do it.  When pulling the transmission on the way out you don't have to undo all the bolts holding the rear driveshaft to the chassis like the center support bearing and the rear tunnel reinforcement bar but putting the transmission back in I highly recommend doing this because it will let you raise the transmission without constantly dealing with the driveshaft interfering in one way or another. I undid the bottom of the engine mount but I honestly don't know that it helped anything. If you do this make sure you put a towel on the back of the valve cover to keep the engine from smashing all the pipes on the firewall. Once the transmission has been pulled back far enough to clear the dowels you need to twist it in place clockwise if you're sitting behind the transmission. This will rotate the starter down towards the ground. The starter bump seems like it might clear if you twist the transmission the other way but it definitely won't. I have scraped the shit out of my transmission tunnel trying so learn from my mistake. You will need a center punch and an appropriate size drill bit and screw to pull the rear main seal. Then use vice grips and preferably a slide hammer attachment for those vice grips to yank the seal out. Do not let the drill or screw contact any part of the crank and clean the engine carefully after removing the seal to avoid getting metal fragments into the engine. I used a Slide Hammer and Bearing Puller Set, 5 Piece from Harbor Freight to pull the old pilot bearing. The "wet paper towel" trick sucked and just got dirty clutch water everywhere. Buy the tool or borrow it from a friend and save yourself the pain. It comes right out. Mine was very worn compared to the new one and it was starting to show cracks. Soak it in engine oil for a day in case yours has lost all of the oil to the plastic bag it comes in. You may be tempted to get the Nismo aftermarket pilot bearing but local mechanics have told me that they fail prematurely and if they do fail they do far more damage than a failed OEM pilot bushing. I mentioned this before but the Super Coppermix Twin clutch friction disks are in fact directional. The subtle coning of the fingers in both cases should be facing towards the center of the hub. So the coning on the rearmost disk closest to the pressure plate should go towards the engine, and the one closest to the flywheel should be flipped the other way. Otherwise when you torque down the pressure plate it will be warped and if you attempt to drive it like this it will make a very nasty grinding noise. Also, there is in fact an orientation to the washers for the pressure plate if you don't want to damage the anodizing. Rounded side of the washer faces the pressure plate. The flat side faces the bolt head. Pulling the transmission from the transfer case you need to be extremely careful with the shift cover plate. This part is discontinued. Try your best to avoid damaging the mating surfaces or breaking the pry points. I used a dead blow rubber hammer after removing the bolts to smack it sideways to slide it off the RTV the previous mechanic applied. I recommend using gasket dressing on the OEM paper gasket to try and keep the ATF from leaking out of that surface which seems to be a perpetual problem. Undoing the shifter rod end is an absolute PITA. Get a set of roll pin punches. Those are mandatory for this. Also I strongly, strongly recommend getting a palm nailer that will fit your roll pin punch. Also, put a clean (emphasis on clean) towel wrapped around the back end of the roll pin to keep it from shooting into the transfer case so you can spend a good hour or two with a magnet on a stick getting it out. Do not damage the shifter rod end either because those are discontinued as well. Do not use aftermarket flywheel bolts. Or if you do, make sure they are exactly the same dimensions as OEM before you go to install them. I have seen people mention that they got the wrong bolts and it meant having to do the job again. High torque impact wrench makes removal easy. I used some combination of a pry bar and flathead screwdriver to keep the flywheel from turning but consider just buying a proper flywheel lock instead. Just buy the OS Giken clutch alignment tool from RHDJapan. I hated the plastic alignment tool and you will never be confident this thing will work as intended. Don't forget to install the Nismo provided clutch fork boot. Otherwise it will make unearthly noises when you press the clutch pedal as it says on the little installation sheet in Japanese. Also, on both initial disassembly and assembly you must follow torque sequence for the pressure plate bolts. For some reason the Nismo directions tell you to put in the smaller 3 bolts last. I would not do this. Fully insert and thread those bolts to the end first, then tighten the other larger pressure plate bolts according to torque sequence. Then at the end you can also torque these 3 smaller bolts. Doing it the other way can cause these bolts to bind and the whole thing won't fit as it should. Hope this helps someone out there.
