wait a minite the 300v is a 15-50w oil..pretty thick for performance only?.....would you reccomend that for standard street use?

i have used used mobil 1 5-50w and found it unimpressive .

nexy will be 0-40 w mobil1 synth for sure...will probably stick with it

Motul 300V comes in a few varieties, I don't know why you would use 15w50 in a street driven skyline.

Maybe 5w30 or 5w40 on the street would make more sense in my opinion.

I guess this is a lubricant question of sorts...

anyone have any recommendations for power steering fluid? I've got steering rack binding issues with my R34, and it's really not nice, almost like constant understeer.

Before i go into serious hardware mods to fix the problem, i was going to start with a top-notch power steering fluid as it might just be a over-heating issue for the current fluid.

Don't mind spending decent $$ for this. Harold from plub.com has pointed me in the direction of Redline ATF (so a transmission fluid) which sounds like might be what i'm after, but keen to know what the best power steering fluid you can get is?

cheers,

Yes, Harold is right. Power steering fluid are in fact hydraulic fluid like ATF, so any Dexron III ATF will worked as power steering fluid.

I can undwerstand after readiing all these that Fullsynthetic is the way to go for TURBO engine, how about RB25 NON-TURBO? my GTS4 non-turbo (RB25DE) has done 112 000KM, and thinking wich oil to go for, at the moment using elf 15w-something but idleing not that good.

Is full synthetic good for NON-Turbo cars? (Given that Money is not an issue ) if so which viscosity 5w-30? 5w-40? etc

Cheers

When the car shutsdown the sythetic type oil thickens less than mineral based oils of the same weight and therefore there is less stress on the engine at startup (better lubrication), where a high percentage of engine wear occurs. Whether it’s a turbo or non turbo car it really doesn’t matter all that much. Stick with the latest API/SAE ratings of SL & SM as these are a far better oil than the SJ oil that was recommended in the early 90’s. I would also recommend a 0w-40 or 5w-40 oil. I still don’t get why people insist on putting in a 10w-40, 15w-40 etc in a street driven car as these oils are way to thick to provide proper lubrication at startup. Hence why you can now buy 0w oils as the oil companies have realised that the lower the weight at startup is way better for the engine. Even though a 0w is still too thick for an engine at startup but its thinner and provides better lubrication than a 5w,10w,20w etc. Since its an old car i would go for a 0w-40 or 5w-40 if the manufacture recommends a x-30 oil.

Mmmmm ic, was in contact with the comnay who brings he REPSOL oil to australia today, (Iknow they are very good quality oil) unfortunately its not available over the counter for dy to day ppl, only registered mechanic shop can buy it from them, but the guy from sales team advised that he will try his best to get me a place if there any in NSW which I can get it off the counter, so far no good news.

I was using repsol 5w-40 when I gave my car to service every six months to mech in five dock, charge $250 and I could seeonly thing they do is changing oil thats all, doggy ppl, so wanna do it my self...

if I cant get the repsol full syn 5w-40 then thinking of going for Motul 300v 5w-40 or Penrite 5w-40?

some say since the car is old i should be using a bit thicker oil like 15w-40 etc which confuce me...........

well full synth is tha way to go for NON-TUrbo cars as well then hey......... :cheers:

Cheers

anyone know of a good place to get Transmax Z??

i've tried AutoBarn, Super Cheap, Repco. AutoBarn don't, Super Cheap do (sold out at my nearby stores) Repco do as well..

BUT these guys only sell in 4 litres, i only need about 1 litre i reckon for power steering fluid. 4 litres = $72

Harold doesn't sell it and i can't seem to find an online shop for it either. Anyone have any other suggestions or places they know sell 1 litre bottles? I may have to just get the 4 litre one

Yes Transmax z only comes in 4 litre bottles and priced around $70 bucks... you want the best, pay for it :D I had to buy around 4 of those suckers when I did my auto tranny service last year... and no.. it was not cheap at all.

SkyKC, All manufacturers I have seen are specifying 0W-XX or 5W-XX oils now. Honda, Ferrari, Ford, Mercedes, Porsche, and others specify a 0 or 5W-XX oil to mention a few. These are appropriate for all engines of all ages of all levels of wear. This second number is the only thing that may change with an older, lose or worn engine. I have heard that oils labeled for RACING ONLY is not usable for every day driving. Often these have more additives that are toxic to your catalytic converters and the environment. These oils generally do not have detergents. These are very important for your engine unless you plan on taking it apart every few weeks and cleaning every single surface. Motul 300V says its for racing cars not sure if its for RACING ONLY. Try German Castrol 5w-40 you can buy it from Harold from Performancelub (i think thats the name) its a good oil. I have recently put German Castrol 0w-30 in my WRX and it seems to love it and the engine is so quite. I guess you have to experiment to find the correct oil then stick with it.

If your still confused and feel like learning more on oils either goto http://63.240.161.99/motoroil/index.html (HIGHLY RECOMMEND reading this although a little long but you can skip some chapters)

Thanks for that :( Im in process of reading the article heheh, by the way most guys here use motul chrono so Im guessing its ok to use for everyday driving....as for the addictive's im not sure motul 300v got it or not, doesnt say anything in their website other than ester stuff.........

and where can I get Motul 300v power 5w-40? no one seems to have it, checkedd with autobarn and repco,.....

Cheers

Edit-

Just found this on Motu website

300V CHRONO 10w-40 - For a wide selection of engines — naturally aspirated, high torque turbo and cars that produce average to high levels of exhaust fumes

300V POWER 5w-40 - For engines that run circuit and street races,

looks like Chrono is the way to go......mmmmmm

I looked for hours and couldn't find the info. Bascially I had to reasearch VSLDs and how they work and found out exactly what you said...then got confused again! haha thanks for that mate.

can some one please tell if the R33 GTS4 got VSLD or a clutch type one?

i would say 10w is too thick, especially with the colder months coming up. I would go with the recent advice here, 0w to 5w to provide the max protection where you get the most wear

Depends on how cold it gets, it's not too thick really as 10w is spec (ASTM D-5293) to flow at -25'c. A good Synthetic will have a lower cP then a mineral though.

    • Was there ever a model of the Stagea m35 that didnt have a badge on the grill? I thought I saw that somewhere, some aero edition or something? I cant find it again? davemoto
    • Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.
    • I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.
    • Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
