This is going to sound like a bit of a dumb question, but here goes

I'm looking to buy a GTS R33 Skyline and have been doing a fair bit of research on running costs (this car is my 18th Bday present, but i have to pay for everything but the car... seeings as i don't earn a lot i need to know how much it'll cost me) Anyways, my mum was talking to a guy who owns a black R33 GTS and he said that it cost him $60 a week on petrol cause he puts in like Premium stuff, (i dunno much about petrol as i'm sure you can tell) He also said that you have to with that type of car, cause the regular stuff isn't good for it. i'm just wondering is this true? Or can you just put regular in it?

I know this sounds dumb but any responses will be appreciated. Thanks.

Sometimes regular fuel can make the car ping.

It shouldn't be too bad running your car on regular (I'm sure alot of people do) Just fill up the tank with premium every once in a while just to be safe :P

I went on to the BP site, and read some stuff about ultimate and then the premium unleaded. Which is cheaper? Im guessing premium, and would this be bad for my car or would it do? Sorry to keep asking questions, it just really need to know. Here's the site;

Oh roughly how much more does it cost per litre compared to regular stuff? Thanks.

Regular: around 85c per litre

Premium: around 95c per litre

There is an average of around 10c per litre extra for premium. Over a full tank, ie: 50-60 litres its about $4 difference. I would highly recommend premium only in your r33. The car was built and designed for japanese fuel which is 102 (or therebouts) RON count which is the octane level in the fuel.

Regular = 92 RON (could be wrong??)

Premium - 98 RON (could be wrong)

You cant actually get 102 RON normally so the closest thing is Premium. Running Regular will most likely cause the car to ping and do wierd stuff.

Premium is the key if its an imported car :P

Never run regular, unless your stuck out somewhere!!

Bad for the engine really, the Nissan manual states PULP and they built the damn thing, so theyd know best!

Ive found Optimax to be overrated, just my experience tho, could just be my area, I usually run BP Premium or Mobil Premium, had a shortage lately.. Speaking of which anyone ever ran 7-11 Evolution, theyve got a no ethanol tag, states 98 Octane and is fairly cheap for premium.

Regular usually sits from 92-94 RON

Premium 96- 98

Depends on how stingy your local servo is really.

Hell, if you want some real get up and go dump some avgas in it :P

Dont feel dumb to ask questions, if you dont ask, you'll never know, and isnt what these forums are bout?

Cheers

If you are driving a n/a 33, you can probably get away with it.. but have your mechanic tune it for lower grade fuel by adjusting the timing of the engine. Its essential for a turbo, but you might get away with it in the n/a as the compression is higher.

Otherwise for longer life, use premium.

I run 98 - thou whether I run Synergy 8000 / BP Ultimate / Optimax usually comes down to price.

If you have those 4c / litre off then Optimax usually becomes the cheapest.

Just filled up on Monday, normal unleaded was 72.x and optimax was 81.x -4c brings it down to 77.x c / litre! Thats the cheapest I've seen in about 3-4 years! (normal unleaded with coupon being 66 (safeway) - 68(shell))

for those in Melb this site should be your bible (no offense to religious folk) - www.racv.com.au Then click the Petrol Prices! ;) It's basically the fuelwatch site, but since fuelwatch started charging you can still get it free at RACV website :)

in melbourne BP is i think always 8c more expensive... so on a 65 litre tank, your looking at an extra $5.... so if you do 400km a week, then your going to spending an extra $300 maybe a year by using ultimate... if you cant afford that, you cant afford a skyline.

bp ultimate & shell optimax are both 98

standard premium is usually 95-96

regular unleaded is only 91

ive run my line on many of the std premiums & the high level premiums and i found that bp ultimate works best for my car (mainly better fuel economy).

in my area bp is 5c cheaper than shell so that helps

dont use regular unleaded as it will increase fuel use & decrease performance in a turbo 'line

supra - all premium fuels are rated at 96.

Mobil synergy, bp ultimate and shell optimax are 98.

I have too heard that shell buys bp ultimate, then adds its own chemicals, but my ex - gf's uncles both work at bp and they both said thats not true...

the main thing you should be concerned about is making sure your car runs on 98... after all, it was actually designed to run on 100ron..

when at a bp station, the grey coloured 'premium unleaded' is 96 octane, while the gold coloured 'bp ultimate' is 98 octane. all of the individual stations i've been to (not all everywhere, just of the ones i've been to) only sell one or the other. places with ultimate usually have it listed on the big sign out the front.

shell also offers optimax (98) & standard premium (96)

p1r4t8r if the Skyline you're getting is turbo, definitely don't put anything in that is less than premium. If you are getting a non turbo though, i would still use premium, but you could probably get away with regular. who here has a non turbo GTS? what fuel do you guys run it on?

I always run on Premium (Optimax).

It's always a good idea to also keep a bottle of that Pro Strength Octane Booster in the boot, in case you need to fill up with regular and there is no premium around.

Just saved running the risk of ping when you kick it in the guts.

      M35 Aftermarket Fuel Pump

      By MBS206 · Posted

      Pressure when IDLING, is meant to be 51PSi... So that amperage value needs to go up a fair chunk... I'd personally be factoring for more like 12amp at least on those runs, and at that point you need to hope the already there wiring doesn't drop you a volt or two, as that's a lot of fuel pressure flow drop off from 13.5 to 12V! Taking idle pressure of 51psi, means the pump will be drawing a MINIMUM of 9amps all the time based on your reading of the graph (3bar base, then allowing an extra 0.5bar for boost = roughly 51psi)

      Wanted to buy R200 longnose LSD 3.9 ratio

      By Ben_D · Posted

      Hi all,  I am in the market for an R200 longnose diff out of a Z31 300ZX, or S12 RSX, DR30 skyline, or similar, in a 3.9 ratio.  Preferably a late model one with the M12 crownwheel bolts.  The only easy to find advert for one of these was my ad back in 2007 when I sold it on this forum.  I sold the diff as I had sold the car it goes to, but as it turns out, after 18 years I got the car back late last year, so now I'm looking for the diff !  If anyone knows where to find a longnose R200 LSD with the M12 crownwheel bolts, drop me a line at [email protected] - Bonus paid if soomeone comes up with the original diff (stranger things have happened !).  Cheers   Ben D

      Back for more after 18 years - and where are the longnose R200 LSDs?

      By Ben_D · Posted

      Hi everyone, I used to post here a bit from 2004-2013, when I owned various Nissans, in particular my S12 RSX gazelle, which was sold in 2007.  As luck would have it, after an 18 year hiatus, the car found its way back to me last year, and over the past 11 months I have had the pleasure of restoring it with my kids.  One thing that I am after in particular is a 3.9 ratio R200 LSD for it.  I actually sold the one out of the car here back in 2007 , and it would be incredible if I could track down who I sold it to, so I can see how they have progressed over the years (and to be honest, to see whether I can get the diff back !).  Anyways, hi all and let me know "where are the R200 Longnose diffs all at these days ?  Cheers Ben D

      G35 Control arm and Compression Rods into a V35 Skyline.

      By sonicii · Posted

      Arms will be the same as the G35 or 350Z, but as above, there was a change in the lower control arm where it connects to the ball joint.  That said, you can remove the ball joint cone from your old ball joints and fit them to the new ball joints.  To be honest, I didn't think the ball joints themselves were different. The main ball joint is a bit awkward to replace, you really need to remove the steering knuckle to press out the old one.  Some people have used tools to remove it in place, but it just seemed too hard to get to. If you are going to press out/in that ball joint, then you may as well just replace the bushings in the LCA and the compression rod.  You can buy the compression rod bushing from Nissan, but the LCA bushes, you will need to go aftermarket. Much cheaper than buying the whole arm.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
