Always 95ron+ If you use regular, try not to boost your car. The minimum you should use is 95 octane fuel.

Edit: I remembered you have a NA Skyline.

seeing as my line was designed to run on 100RON, i'm not gonna be a tight ass and run it on 91 or 95RON. it's only a few dollars extra for decent fuel ffs

bp ultimate or vpower racing :)

I just want to add that running your car on 91 octane fuel could give you less km from a tank than if you're running on 98. The money you save by running on 91 octane fuel is not all that much if anything at all when you're filling up your tank more.

In other words, you could get 300km out of a tank of 91 octane fuel, but you could get 350km out of a tank of 98 octane. Your engine is tuned to 100 octane fuel.

The BP up here (karratha) dosnt sell ultimate 98 they only have premium. Premium is the highest octane we get :yes: so i might have to get my car tuned to that. . . . or add tollune (spelling) every time

These cars were only ever built for the local japanese market. Japan as far as I know isn't aware of fuel lower than at least 95RON so none of their cars are made to run on 91RON fuel. Especially skylines and related cars. I believe japanese fuel is above 100RON so I'd recommend 98 as its the closest you can get in many parts of australia. Some states have 100RON (lucky ppl) although that comes at a higher price too. 98 is quite safe.

Depending on how your car is tuned, you may have trouble even with 95RON - i know my stagea pings a little on it. Its BP Ultimate98 for my stagea. Have tried shell vpower but wasn't as happy with it. Each to their own. :yes:

Offtopic a little - I often wonder how many people who buy these new hot hatches and other new aussie-delivered cars realise that they need to run on 95RON or higher??

Many of us are only vaguely aware that 91RON fuel exists, and yet most people out there are unaware there is anything OTHER than 91RON... :)

It doesn't matter who sells it, if its cheap, people will put it in their cars.

BP ultimate in my GTR, although i run boost 98 in my civic.. and it sure feels real peaky lol and gets more km per tank, so i might try run that in the GTR and see what i get on dyno to see if theres any difference

I only ever run BP Ultimate. I've found it to be the best fuel for me.. Never really tried Shell optimax though.

Previous owner used to use Caltex Vortex - he filled up my car with it prior to handing it over, car would ping occasionally at higher revs. BP Ultimate has not done this.

Seriously, how much do you really save filling up with cheaper fuel.... a few dollars. Then take into account less k's from the tank of cheaper fuel..... if you need that $5 you saved that badly, maybe you should buy another car.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
