Never less than 10 W anything in a Subaru turbo if you want to keep the engine in one bit. REGARDLESS of all the technical jargon.

Well there you go. Thanks David. Does Subaru not recomend 5w30 oil?

miller cfs 10w50 is ur best bet

tim's wrx

Yeah - Subaru say that 5w30 is "preferred" for my 2005 WRX as per the owner's manual. For severe driving conditions they say 10w50 or 20w40 or 20w50

pslewis

When will people learn

10W - 40 is what Subaru recommend ...... STICK WITH THAT!

Too many Hobbyists play about thinking they know better .... 50 is treacle and 5W is water - go ahead use it, after all it 'looks' impressive!

Yeah maybe they do, but their current track record for busted engines with no explanation is not great.

We are happy with 10W40 or 10W50 or 15W40 & 15/W50 The Castrol RS 60 grade is, in my opinion, too far the other way and will cost power. After all 75 grade is gear oil.................

As I understand it the larger number is what the oil actually is and the lower number is how it behaves at minus 5 celcius.

David, Just a quick question...

what particular Gear oil does API regularly use in 6 speed boxes?

cheers

Generic 75W90. If we get a chance on a fresh box we use Motul semi synth 75W90 as it will prolong the life of the bearings and synchros BUT putting it in at anything over 20,000 miles is too late to make much of a difference, , long term.

For hard track use we use Motul Gear Competition 75W140 fully synth. BUT it is eye watering expensive at £32.50 per litre. +VAT

However, they say that once you have bought it it will last forever, just drain it and sieve it through some ladies tights [ ideally after she has taken them off ] and re-use it as it is ' for life ' oil.

So in the long term it may not be too expensive providing some clot doesn't drain it and bin it.

Thanks for the reply David. I've just had my 6 speed box overhauled by you and your team and the gear shift has never been smoother. I just didn't really get chance to ask about the oil at the time. Cheers

Thanks for letting us know that you're happy - Good Luck, thanks for your custom.

David

Apologies to the OP for the hijack......

****. I've just chucked a load of expensive synth gear oil away that had only done a few hundred miles (because I drained it for a release bearing collapse and got bits of crap in it). Good idea for next time though.
