why do the drift filters have a magnet? if an engine is losing a measurable amount of metal each service the engine would screw itself up pretty quickly wouldn't it? or is it more precautionary, because having metal filings in the oil will quickly degrade the engine?

tuf: nulon isn't a bad oil but it isn't fully synthetic, which is what most of the guru's strongly recommend. the royal purple, motul 8100 xcess and sougi s 6000 are all fully synthetic group IV oils for roughly $75-80, thats 10-15 more than the nulon but are highly recommended oils. or, like a few people seem to do, call great western, find a distributer, and go pick up some sougi s6000 for $60 and laugh all the way home knowing you got grade IV oil for grade III price :)

perzn: most people use the motul 8100 xcess, and thats across a really wide variety of mods. its a really good oil and a great starting point before you experiment with other oils.

for the record, my car seemed a lot happier on dirty motul 8100 than on clean nulon (doing 1000km changes to flush out the engine cos previous owner didn't take care of it, lol and not keen to use an engine flush just yet)

anyways, read some earlier posts guys, take 20 mins and skim through the last 10 pages, there's so much good info in this thread

what do people think about the full sythetic nulon 10w40 it reads up well?

:) Its not a full synthetic attall in spite of what the packaging reads, I used it for two oil changes with about 2000ks/3months/summer between , it looked and felt as though it had done twice the ks it actualy had when I changed it and went up to $59.95 for 5 litres , I gave it the flick , went to a Penrite HPR10 it's a 10 50w semi $39.95 for 5 ltr, thats enough for a streeter that dosen't get flogged and changed every 4 months. IMO anyway.

Car is a R34GT-T 83000ks with a tight engine and stock except for exhaust, wheels, springs.

I am considering SOUGI for my next change, seems to be being liked--we'll see. :)

It you can forget for a minute it advertises itself as a fully synthetic oil, then it's not bad. But it's not a genuine fully synthetic oil. It's also expensive when you realize it's only a semi synthetic. The price is between $50-60, and you'd be better of tracking down a Gulf Western distributor and purchase a 5L bottle of Sougi S 6000 for $60. It is a proper fully synthetic oil equivalent to Royal Purple and Motul.

hey guys im buying oil for my r34 gtt for the first time and im thinking of going with the motul 8100 xcess. i do run a HKS GT-RS turbo with 13psi boost.

so is the motul 8100 xcess good? and idont realy know what viscosity to go with?? thiers 10w40 and 5w30 .. so which one should i go with considering its winter as well?

The 8100 is a good oil, but it doesn't come in 10w40, only 5w40. So if weight is important and you really want or need 10w40, then you'd going to have to go with the more expensive 300V Chrono, the cheap option of some Turbolight, or go with Royal Purple. But I'd recommend the Sougi S 6000. For $60 you get the same weight oil as the 300V Chrono for half the price. $60 for 5L can't be beat for a genuine fully synthetic oil.

Aye, the more I look at it, the more I get annoyed that Nulon's advertises they product as being "fully" synthetic oil.

Basho, for sure give the Sougi a try. I went from Penrite HPR10 to the Sougi and am glad I did.

yeah, if you're going to go semi-synthetic, you don't need to spend $60 on nulon.

one thing about weight, and im sure mr. kong knows this too, the hot weight is most important. the cold weight is just the viscosity when cold, so comparing the 10w to the 5w, the 5w will get to the cylinders and round the engine, providing lubrication and protection, faster than the 10w, but the 10w will provide better protection and lubrication when it gets there, when cold that is. either way, they're getting closer and closer in viscosity as the engine temp increases, and its properties of the oil at temp when thrashing or driving long trips that can harm the engine.

the biggest advantage of 300v is apparently the compound it's made from. the motul 8100 xcess is group IV, so fully synthetic, but the 300v chrome is group V, some double ester compound, which is not as prone to heat and wear degradation.

But I'd recommend the Sougi S 6000. For $60 you get the same weight oil as the 300V Chrono for half the price. $60 for 5L can't be beat for a genuine fully synthetic oil.

sougi is the best performance for the dollar, and a damn good oil according to everyone who's used it. can't wait to give it a try

Aye, the more I look at it, the more I get annoyed that Nulon's advertises they product as being "fully" synthetic oil.

i totally agree with this, got conned a couple of times by the supercheap/autobarn whatever that this is the oil to use. maybe on commodores, but not the best for skyines

Galois - Sougi is actually a group V because of the polyol ester base. So you're getting group V for group III price :D

That's why I compare it to 300V as a performer because there aren't many group V oils out there and they are on par for specification.

Because people don't know about it Galois. You're going to be hard pressed to find Sougi in a store for starters, and secondly using Nulon as an example there's a whole bunch of false advertising as to who is really selling fully synthetic oil. And thirdly, if you had never read this thread, you'd never know anything about Group III, IV and V grade oils. I know i didn't. I just went on fancy packaging and what the product "said" it was.

It's a shame GW don't try and market Sougi. I mean it's not like it's in stores and they give it little promotion. It's not even in stores for starters and gets only word of mouth promotion.

And about the Drift filters having a magnet in them, I don't think it's just for metal shavings. There are all sorts of fine particles, dust, sand etc, that it can also pickup. How they became magnetized I'll never know, but whenever I have a magnet lying around, it mysteriously attracts these fine particles to it. So if it's in an oil filter, it can only help I reckon.

Aren't these small bits of dust etc caught up fragments of metal that they're attracting? Drift are known as pretty good filters, and loving the idea of not bashing knuckles just to get the oil filter out.

Also, does anyone know where the oil pressure sensor is? its always interesting how different oils and filters change the pressure reading.

cheers!

Well it's not unlike voting for a political party. People have their loyalties to particular brands and rightfully so, because you find something that works and you'll keep using it / recommending it to others. Motul have built up a very good reputation amongst car enthusiasts for their oils. Gulf Western is not as well known besides their loss leader stuff that gets flogged in auto part stores. Even though I believe Sougi is every bit as good as 300V there's no convincing some people, even if everyone started using the stuff. Honestly I'd be cautious myself...this is the automotive industry where you almost always get what you pay for. The only reason I gave Sougi a go in the first place is because A. I got it for free and B. It wasn't my car lol. Half of me wants to spread the news about it and to ensure GW keeping making it, the other half wants to keep it secret like I've discovered a fountain of youth muhaha.

Alas...engine oil is different to bolting on an eBay turbo. Like I've said, you'll feel if an oil isn't right before you do any damage with it. No company retailing oil can afford to put out shit - all companies have public liability insurance in the case of a bad batch of oil. People in this thread have tried oils like Nulon and found they're not happy with it, they've changed back to something else and their engine won't suffer for it. But if you reckon its hard convincing the public to try an oil, you should try convincing mechanics to switch from a brand they've been putting in cars for 15 years!

Magnets on oil filters aren't really necessary given your sump plug is supposed to do that job...any extra metal it collects is just stuff that would have / should have stuck to your sump plug. And it's better at the bottom of your sump than a high pressure area where oil is supposed to be getting filtered. Put it this way, if it was a good idea it would probably have come that way from factory. I'm in agreement with you Galois, if your engine is shaving off significant chunks of metal, the damage of this metal circulating around your engine is the least of your worries :)

It could be metal sure, but I remember when I was in Rome last year and I bought these really cool looking egg shaped magnets. The trick is to fling them up in the air while spinning. They make this noise similar to a cicada. Dropping them even on clean concrete, you'll find they are covered in all kinds of rocks and dust that won't brush off. So somehow it was already magnetic, or simply by coming into contact with a magnet, it becomes magnetized.

Now if I was to then think what could be in my engine, it's certainly possible these same small particles and things could be there. Isn't that the purpose of an oil filter to begin with, to filter out anything potentially harmful to our engine? Or is it done more on a chemical level to help the quality and consistency of the oil itself?

I'm just scared too many people will buy it, then the price will go up or something lol. That or GW stopping production of it because they don't sell enough. Can't win lol

GW won't market Sougi because retail sales make up little profit for an oil company, let alone a single line of oil. That said, GW don't spend a great deal on marketing within the automotive industry anyway. Their money is in mining, agriculture and farming. The extent you'll see of it for now are the odd magazine placements, V8 supercar sponsorship and some television spots in rural areas.

Retail sales for oil companies are there mostly for brand awareness. That's why Nulon pay to fill a whole shelf/stand full of their product, and how they came out of nowhere to be so well known. The real money is made in supplying volume oil to mechanical workshops, industrial users. Where retail helps for an oil company, is when a customer goes to a mechanic and demands they use so and so in their car.

Yeah well that's part of the risk you take. Worst case scenario they stop making it and you switch back to 300V lol. But they've been making Sougi for a couple of years now and I can assure you I'll be ordering more than a few bottles if I ever get news of them ceasing production :)

Its a physical separation more than some sort of chemical regulator, the filter is there to make sure that only liquid oil is circulating through the engine, you're right when you say dust etc are filtered out

Edited by Galois

Yer I just PM'd you about the cheap supplier. It was a demo website that I'm guessing hadn't been priced up correctly, as their 205L drums cost significantly more than ours did despite their Sougi being $20 a bottle LOL. Not to mention once we ordered a heap of them the website mysteriously disappeared :)

    • See if you can thermal epoxy a heatsink or two onto it?
    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
