What are the best oils to use on the bugeye six speed box, and rear diff, which is a lsd i believe. my scoob is a 51 plate V7 STI Bugeye. And what parts do i need to do the oil change.

 

somebody must know!!!!

 

I use Redline shock proof I think its called that !

 

NOTE: All Subaru AWD Transmissions use a 75W90 Oil. The rear end, including the 2000 models w/ viscous rear diff, also uses a 75W90 oil without friction additives.

REDLINE OIL
MTL This oil is too low of a viscosity to be used in the Subaru AWD manual transmission. Not Recommended.
MT-90 Great balance of friction and lubrication. This is a good choice for a street/auto-x car. Highly Recommended.
75W90 A GL-5+ grade oil which has a friction modifier and is more suited for a mechanical limited rear end instead of the transmission. If you want friction in the transmission, use the MT-90.
75W90NS Another GL-5+ oil which offers good lubrication and bearing life. Best for the rear diff but can be used in the transmission.
Shockproof Expensive but a good oil for those who are abuse to the transmission/rear end and/or do quite a bit of racing. Use the SuperLight rated oil. Not a requirement for everyone but good stuff nonetheless.


AMSOIL
Series 2000 75W90 Affectionately called "Smurf Oil" due to it's blue color. Great lubrication properties make it the gas mileage king. Take alot of long trips? Smurf oil is the ticket. Used and developed for fleet vehicles, not recommended for quick shifting drivers.
75W90 Great lubrication properties. Less expensive than the Series 2000 but still works very well. Very good bearing life. For those that favor bearings over synchros, Amsoil is one of the best!



Conclusion
As you can see, there isn't necessary a BEST OIL that can be recommended to everyone. It really depends on how you drive the car and your particular needs. Some owners find that they try 2 or 3 different oils before they find the one that suits them best.

 

I'm not bothered abut the price, i want an oil that is going to protect my six speed box and diff, the best. I do a lot of town driving in the week, and then like to give it a blast at the weekend, up down the motorway and SAFE city roads. So it is mixed driving i suppose. How much do i need for the box, and how much for the diff, and do ineed anything else for the job.

 

3.7 liter for the tranny, .7 for the rear diff. Not sure if the STi is the same as my WRX though.

 

Which make though? and grade? i am in your hands on his one.

 

Did you read my first post? As far as brand goes, that is nothing more than personal choice. Do you like McD's or Burger King? Moble 1 or Castrol?
Me personally, I like Royal Purple oils since it is fully synthetic and not just carbon breaking like Moble1, Castrol etc.
Amsoil, Redline and NEO are a few other fully synthetic (base V) oils.

 

Idid read your post and i am very grateful for your insite, but do you know the spacing between perps on an ornimental wall? or the hinge space on a norge oak panelled front door? I am but a simple carpenter who is very confused by your terminology, i really do appreciate your imput, espec as you know what you are on about. But me no idea, all i want is the best for my girl and the best brand and grade and where can i get them from? Ihave no personal choice as i have no idea

 

Hi,

I use Castrol Syntrax 75W/90W from Halfords around £9 Litre.
I have a MY95 WRX.

Powerstation put Silkolene Syntran (sp?) fully synthetic in my gearbox/diffs when they serviced my Type R. Seems to be working out ok.
