the answer to your question is:

use whatever fuel you can get to that is as close to the jap-spec 100RON as possible

after all, that's what the car tuned for. If you have had it re-tuned then that's a different question (as ferni said) as it may have been optimised for our 98RON

cheers,

Warren.

It will die for sure on 91 octane.  You have been warned.

You need the best 98 octane you can find unless you have retuned it.

thanks for this info...i thought a skyline would need premium...so i've accepted the fact that fuel is gonna cost me....lovely

Yes Optimax is 98 Octane Premium, Shell also sell "Premium Unleaded" which is 95.

BP, Caltex and Mobil all sell 95 Octane as well as 98 octane (Ultimate, Vortex 98 and 9000 are the 98). Different locations might carry either or sometimes even both the good nad bad stuff

I know its a bit O/T, but did you see on the news, fuel jumped 5c today! WTF? Why?

on sunday i was on my way home from work, got back into my suburb and drove past shell. pump price on Unleaded was 1.11c. on my way to work just 4 hours earlier, it was about 1.18c or something, so i went home, got a 4c off voucher and filled up for 1.07

it stayed at 1.11 for about 2 days, and then on the way home from work, i noticed the pump price at the same servo at 1.23! thats a 12cent jump!

i heard the fuel companies took off the discount to kill off all the independant/local fuel companies??? (dont know if thats true)

So, you would damage an R33 GTS N/A if you ran it on regular unleaded??

If 98 RON Premium is a must, is there any fuel saver options for this car? I'm not fussed with performance loss.

    • You shouldn't need to massively fatten up the mixtures for cold conditions. For one thing - 0°C is not that cold. For another, the Haltech will be using the IAT sensor to tell it how dense the air air, and calculate the correct amount of fuelling. Then the cold start enrichment is added as a % on top of that, so it should scale with the main fuelling. You might also doubt the IAT sensor at this time. You're not using one from an RB26 are you? Using a nice Bosch sensor or similar? Happens. Some wideband units take great pleasure in killing their sensors. Put another wideband in the tailpipe and compare. Or just swap the sensor to a brand new one and see.
    • Oh, my misunderstand. When the car was running, it sounded ok, but if I gave it any gas it wanted to die but caught itself afterwards. It's very different from how it was a couple months ago when it was warmer outside. The logs show that the AFRs are better during, what I assume, is warmup enrichment. Because it's cold, and air is more dense, should I work on the enrichment bit?
    • yess of course im not using 2nd hand parts from my spare engine, but the place where i live is hard to find parts for the RB20DET ,but for the RB20E is everywhere including new ones and a lot cheaper ,because for the RB20DET you have to order it overseas to get one and it cost a lot of money 3x the price to be exact. so i ask this topic because if i can use the new ones but for RB20E is it compatible or not. if not im screwed haha, not totally screwed but i have to save a lot of money first before i can begin repairing my engine, thanks for the information before.
    • Unless my sensor just died, was only a couple months old, I strongly believe it didn't. How can I test it? I never mentioned it being 20:1+?
    • Well, you wouldn't use 2nd hand bearings out of another engine anyway....so just buying the proper bearings is obviously what you're going to do. The crankshaft would be common. The conrods might be common. There is essentially nothing else you would be able to use.
