ok i have been having an argument with someone about not being able to put normal unleaded fuel in my 33 instead of premium.

i dont really have anything to back up my argument but heard that putting straight unleaded instead of premium can be harmful to the car.

can someone who is a little more educated in this please help me out with why i cant put normal unleaded in instead of premium and if i do what will happen.

thanks!

I think after a while it would as it won't burn as clean as premium.

When I first got my R34 GT-T I put in Premium Unleaded 95 octane and it ran ok, but then the next time I put in 98 octane and it ran alot better. More fuel economical (I do mainly hwy driving) and started better as well as sounded alot cleaner.

My label actually specifies at least 97 octane. Would imagine R33 would be the same?

I put 91 in today, because there I was in the middle of nowhere, and had no choice... didn't ping on full boost..

still it dosn't pull very hard.. infact, it's really crap. Even if you can get away with using it, don't. If you can't afford permium, then buy premium anyways....

thanks guys...

yea nah thats what i thought..i wouldnt put unleaded in it anyways not worth it.

my dad has a fuel card for work n has been offering me to fill up my tank but it will only use unleaded.. after extensivly telling him i cant put unleaded in it he wont listen.. just needed some other opinions on it so he can shut the fk up about it

he was a mechanic like a million years ago..hasnt been in the game for at least 10 years but still thinks he knows it all..he knows nothin about skylines but thinks they are just like ur average holden blah blah blah he rekons wont kill it if i put in a tank of unleaded then put premium in after it.

just needed some advice from people that actually know what they are talkin about to shove in his face so he gets the picture

thanks again :D

Nissan's anti-knock measures will be as good as you'll find I'm sure - I once put 96 RON in my R31 as that was all I could get and it had stuff all power. Didn't hear it ping at all though.

It can be done but it's not nice to your motor. The ECU will retard the ignition timing like crazy to prevent pinging.

If you're running higher boost it's a different story. The ECU only has so much adjustment it can make and if you push it outside that range by increasing power then it might ping regardless. Plus extra boost, that's when you damage things.

Personally I think anyone who puts less than 98 RON in a skyline doesn't deserve to own one!

You don't have to hear the pinging sound for pinging to have already occurred, so you could be causing damage to the engine without knowing it.

Definitely agree that it's a good idea to carry some of that octane booster for when you're out in the middle of know where with only regular unleaded.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
