Well...

Everyone's got their favorites. Which one is the best? who knows.

Personally, I use Mobil 1

you said gear oil?

I use Redline. I think the car is a bit smoother, shifts a bit easier.

Cheers

Thumbs up Redline

My vote is for Redline as well. I replaced my gear oil before a track day with MT90 and the tranny is very smooth. I have no problems downshifting into 1st, no grinding, etc.

I switched to Motul. Initially it was smooth as butter. I'm finding it's stiffened since I first put it in. I still have problems w/ reverse on cold starts.

HomerJay and windfactory, can you elaborate on the performance of the Motul. windfactory, i got your email but had a difficult time understanding it. Could you explain any more? It really seems there is some one that has a complaint for every different type of synthetic tranny lube. I guess it's either the Subaru stuff or try to find the synthetic that works the best. Right now, Motul seems to be pretty good with Redline 75w90NS in second? Anybody else have something to add?

umm...ok, but 1st I'm not a pro-writer in English...so please try to understand what I wanna share....
here we go: - part 1 -
Fluid lubrication-To the usually in state, as for the oil the oil film is formed fixed load which (is) the pressure (viscosity) with. This state is called the fluid lubrication, the oil prevents the direct contact of 2 face to face of the metal as a fluid.
In order to maintain this state the pressure which supports the load of 2 face to face in the oil becomes necessary. This pressure occurs relative motion of 2 face to face and due to the speed of the oil which is sent from outside. But, pressure as a fluid of the oil in under condition of high load, (just viscosity) with it becomes impossible to maintain the oil film. In that case, it causes the oil film being cut off with, condition, such as temperature and viscosity such as speed of sliding between the metal and the load to the lubricating aspect (rpm of the engine) it is exposed to the state of of the boundary lubrication to which the metal and the metal contact directly.

- part 2 -
Boundary lubrication - In the territory of this boundary lubrication, the ester shows the efficiency greatly. With the other based oil friction in the difficult boundary lubricating territory (boundary friction) being to make decrease substantially, it does. This mechanism as description below has become the mechanism. Among the molecules which the ester has, the oxygen (O) with the hydrogen (H) it adsorbs into the metal surface electrically with each one (-) and (+) polarity, becomes the admolecule membrane.
Admolecule membrane - It is big difference of the oil where with just viscosity creates the oil film.

For example as for this difference, it is expressed to remarkable even in lubricating efficiency of engine top at the time of engine starting. When it is lubricating depends on just the pressure (viscosity) of the oil, when the engine stops, that pressure disappears, simultaneously the oil falls to engine lower part due to gravity. After that, the occasion where the engine re-is made to start, until the oil is sent to engine top by the oil pump, between, the oil does not exist in 2 face to face of the metal, becomes that the boundary lubricating territory appears suddenly. This it calls "dry start", it can call the most dangerous state for the engine.

The engine of the general marketing car repeats stop and go with usual travelling, but the reason that is here in reason, it is severer condition than the racing car. On other hand, because the admolecule membrane of the ester does not depend on viscosity, also after the engine stop remains on engine top, prevents "dry start".

The oil of the time before the ester had been about probably to maintain fluid lubricating state viscosity (pressure) due to maintaining as long as possible. In other words, being to have the concept that about the hard oil oiliness is strong.

- Recording to my research -
Mutol could change the former concept of high viscosity = high oiliness by using the ester in the based oil of the synthetic oil. Because the character which the ester basis in the based oil it tries to adsorb into the metal surface with electric positive characteristic with polarity, maintains oiliness is. This polarity does not change with the viscosity and temperature of the oil.

Sorry about the mess typing.....hope it helps.....

I'm not saying Redline/other brand cannot provide the right one (oil) but different companies have their own research and technology, therefore, choose one you feel good and enough for your motor.

but just my opinion....
Designed for WRX turbo engine (250ps - 280ps) / Porsche boxer turbo
engine oil : Boxer 15W-60 SL/GL-4


Designed for all transmission with LSD
gear oil: Redline and Mutol; technology based JDM, and improved with UK racing teams' tech. , WRC racing teams' tech.





p.s. sometimes i still not really understand what i type....

dear lord, you are definitely not a "pro-writer".

is there any chance that you could send us some mp3s of you talking? i hope you speak better than you write.

i definitely appreciate what you are trying to do here, and i DO want to learn. with that having been said, i cannot understand a thing you are trying to explain.

man that can of oil looks ghetto!! is that synthetic? 15w60 seems like it would be pretty light for a crankcase oil, but motul could perhaps know what they're talking about.

also, what is the exact name of the tranny oil you use?

I actually switched to Redline 75w90NS just last week. Seems like pretty good stuff. Slightly smoother shifting overall, but 1st gear still sucks. Oh well.

Everybody says that synthetic is smoother at first. The real test is whether it lasts for a while. Good luck.

thanks guys for the input, especially windfactory...although i didn't understand a word you wrote.

i currently have synergism in my car. seems to do the job but i just bought a bottle of mobile 1. i don't know if i should use it on the wrx or my golf? i think my golf needs it more cuz i think it hasn't been changed and it has 153,000+miles.

For non turbo 2.5RS, i would like to say,
Mutol 6100 synergie 5W30 100% synthetic engine oil in CA summer and winter. (always warm up engine every morning)
&
Mutol Motylgear 75w-90 Semi-Synthetic Gearbox Oil in low temp area also, very smooth. (now i'm using)
or
Mutol Gear 300 75w-90 100% Synthetic Gearbox Oil in normal/high temp area.

For WRX turbo, i would like to say,
Mutol 6100 synergie 5W30 100% synthetic engine oil for winter,
Mutol 6100 synergie 5W40 100% synthetic engine oil for summer.
+
Mutol Gear 300 75w-90 100% Synthetic Gearbox Oil (well, this one usually use for under high temp)

For Brake Fluid:
I would say try Mutol Racing Brake Fluid 600 on WRX turbo, it far exceeds the standards of DOT 3 and DOT 4. Xtremely useful.

For noisy gearboxes:
May wanna try Gearbox 80w-90 Mineral Oil, it is high resistance under heavy duty conditions.

Here are all base my research, just my opinion.

Alright, now there's something everyone can understand. Thank you windfactory!!! I am currently using the RBF 600 brake fluid and have not had any problems with it. One question about the mineral oil for the tranny. Now that just doesn't sound right: putting mineral oil in your tranny. Perhaps I'll take a gander at their website later on to see what that's all about. Thanks again windfactory.
