The only reason people dont use Mobil 1 ow-40w is that Subaru have not tested the oil for Subarus, so it will invalidate your warranty. I spoke to Mobils technical help desk last week and was advised as soon as my warranty runs out to use Mobil 1 0w 40w. The Motorsport version is not ideal for normal/fast driving. If you have warranty remaining then the Subaru dealers can supply Mobil 1 5w-40w made specially for Subaru.
Any queries send a mail to Mobil, the lady I was talking to was Barbara, she didnt mind me posting her email :

Marcus - Halfords are doing a spend over £50 on service parts and get 20% off.
Alternatively ill pick some Mobil1 up in France for you on Friday, my folks live in Langton Green (Dornden Drive) not too far from you, I live in Tonbridge. Hope this helps to clarify a grey area.

 

OK, as I've got the WRX Wagon and at present no handbook, what engine oil should I use, eg; Mobil F1 0W - 40???

Have not checked her oil just (sill I know) but I want to do it before Bentley on Sunday, so I'll probaly go to halfords tonight, so I want to know if they'll have what I want.

 

Markus,

Steer clear of Mobil 1 0W/40 as it's way too thin for the Scoob.

I run mine on Mobil 1 Motorsport 15W/50 which is one pukka oil. I believe Halfords are doing an offer on the 4L containers at the moment.

Akira:
Cheers! I'll pop down and get some tonight.

 

lordLucan:
Thanks for the offer, but I've just checked the oil and the levels are fine. I was told my my brother, whilst he was 'looking' at the scoob that the oil was a little low, guess I'll have to ignore his advice in future.

BTW - if you visit your folks much then we may bump (hopefully not scooby wise!) into each other

 

Magnatex is best according to one internationally renowned Subaru rally engine builder.

 

hi all,
the mobil 1 from french hypermarkets is a 5W 50 ,so would this be better/worse than the 5W 40 that main dealers can use?

I got 3 packs of the stuff, before i realised that i can't use before the warrenty runs out. It should keep though.

PLEASE do tell : which internationally famous rally firm is that..?

 

It would be improper to name them, but they do know what they are talking about :-)
