The Goods On Oils

[some_cs_student]

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.

[some_cs_student]

Has anyone had a look at the discussion at the 5w40 Fuchs Synthetic Oil discussion on this forum.

Any opinions?

Mobil Synthetic S 10W - 40

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,

daniel

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.

Yeah I have Castrol Transmax Z in my auto tranny... I was told it is one of the best tranny oils you can buy... pretty dear too but the gears run really good.

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

[SS8_Gohan]

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 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

[SkyKC]

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?

[JImports]

can I use martini 0w40 on a GTR32?

Is it a good oil?

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

[Busky2k]

Theres nothing too thick about the 10W40 really. Especially if the cars got a few miles on it! I'd still go the 5W40 though if possible.

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.
