[QUOTE=scooby182;657037]So sorry to bring this old thread up..
But I was told by a very well known Subaru mechanic that
he uses Castrol edge 10w60 in his rex's,
He recomended it for alot of wrx's and also one's with higher k's
Any thoughts people ?[/QUOTE]

You have a '96 2L use a good quality 10w40.

[QUOTE=Mister Two;657052]I use 10w60 Castrol Edge in my ej257. Been that way for the last 50,000km or so this engine has been running. Its good stuff.[/QUOTE]

Are you running avcs??

Who is recommending 10w60??

[QUOTE=Rossco;657056]You have a '96 2L use a good quality 10w40.[/QUOTE]

Yeah true... 1996 2l turbo with higher k's..
sorry i dont wanna say who recomended the castrol edge 10w60
I dont wanna start any shenanighans, hope all can understand,
but thats maybe why they recomended a thicker oil for my car, coz of the high k's.

Also, this may sound stupid... what avcs ?

No AVCS. my98 heads.

No recommendation really. Just using what works. Its been good to me this whole time. 50,000km @ 340hp and just under 500Nm must be a good sign.
Doesnt burn any oil either over 5000km.

Correct me if I'm wrong but MMS use castrol 10W60 in most of the cars

I guess it really depends what works for you the best and seems like people are happy with 10W60. I've always used mobil 1 in all my cars and some always use castrol in their cars with no issues from either as long as the grade is suitable for the condition of the engine.

Always a good read out there to see what people have been using

MMS use edge 0w40.

Those links you posted show a majority of negative responses to using a 10w60 oil in a subaru.

Castrol recommend Edge Sport 5w30 or 0w40 & edge 5w30 or 0w40 for all ej's 1998-2012

Extreme use 10w60 (which isn't street use, where you'll never get it hot enough (~140C) to flow well) .

I'll stick with 5w50 Mobil 1 & my builder agrees.

Horses for courses, you can use Play doh in your sump for all I care.


Maybe take the time to read these posts from a Subaru enthusiast who is involved in the lubricant industry:

Using cusco 5w40 from Evo r

/csb

i noticed an improvement in engine response and turbo spool up and subsequently general power when i went from penrite 10w60 fully synthetic to motul 5w40 8100xcess fully synthetic

and also i noticed a drop in these things when i went from penrite 10w40 fully syn to 10w60

Hi, guys.
I'm buying a 2008 STI, and wanna do a oil change straight away. I used Mobil 1 5w30 in my WRX with no problems.That car has done 20000km with MRT XB kit. Should I use mobil one 0w40 or 5w30 EP or stick with normal 5w30? I do a bit performance street driving.

Thanks in advance.

Either 5-30 or 0-40 mobil1 would be sweet imo
