going to change oil and filter would mobil 1 10-40w be ok to use if not wot sould i use thanks

 

I use Millers CFS 10w40

 

Yes any fully synth 10W-40 in a Classic is highly recommended.

I use the same as Chris above.

 

ok thanks halfords have got an offer on 5L £15.99

 

Not saying it's crap, as I've never used it, but there must be a difference in quality, as £16 stuff compared to the Millers £50 stuff.....?

 

mobil 1 is normally £40 so its not that cheap

 

Oh right, fair enough mate

 

At that special offer price, I say get it.

Although never base your oil buying decision purely on price only - you should always fit try and fit the best recommended brands/weights for the EJ turbo engine (regardless of whether its 'expensive' or not). Obviously this is a different situation in that you're getting a proven brand for a special price.

Don't skimp on oil filter though - ONLY get the OEM Subaru item.

 

glenburgie cars beside me told me to drain out the mobil1 10w-40 and put in shell helix,

 

Shell Helix semi-synth is the Subaru recommendation I think.

I can't believe Mobil 1 10W-40 is a 'bad' choice (although I'm aware it's not the most popular brand for the Subaru). Most owners seem to opt for Silkolene, Millers & Motul from what I've gleaned.

But "the oil question" is the most contentious one re the Subaru engine and will run and run and run (there's a tenuous, unintentional pun in there somewhere)...
