December 12, 201510 yr Book says 0/30 oil. 5/30 can be used to top up. Told by garage they,d used 5/30 . When querying it i was told they had checked with Subaru and that it was good and probably better than 0/30. Am told the 0/30 was because of the hotter running turbo. Have a forth year warranty taken out, could this possibly compromise on its cover?.
December 12, 201510 yr I wouldn't worry too much- most vehicles have 2 or 3 recommended oil weights and the odds of it causing a problem and the garage checking/ testing the exact spec used in the event of a warranty claim is slim Sent from my iPhone using Tapatalk
December 12, 201510 yr Author Martyc Thanks. So in future, is it to be 0/30 or5/30? . Given the choice.?.
December 14, 201510 yr I also have s 2.0D XV and To be honest I just bough half a litre that I keep in the boot from the dealer. Not sure what it is, I'd have to check. But if you get it from whoever does your servicing and use that then if there is a problem you can at least go back to the servicer and question their use of that oil.
December 14, 201510 yr Right I've just checked, now I get mine serviced by a Subaru Main Dealer and they're using Petronas Syntium 5/30.
December 14, 201510 yr Author My service was at a main dealer. The point is, the book says 0/30. I,m told becuase the Turbo gets that much hotter.
December 14, 201510 yr Don't know, but you have to assume that the service at a main dealer will use a suitable oil, otherwise Subaru would have something to say. If you're in any doubt then go with what the book says. I just bought half a litre of what the dealership have been using. Sent from my iPhone using Tapatalk
December 14, 201510 yr The key thing about oil is the second number, this is the minimum viscosity at 100 deg C, the 1st number is its maximum viscosity when cold, this helps cold starting. So 0 is for cold starting, 30 is minimum viscosity for hot running. From what I know the 0 or 5 isn't a big deal but putting 0/20 in for example would mean your oil would get too runny and that could cause problems for the turbo. Using 0 or 5 should be fine as long as you let your engine warm up before giving it some beans which I'm sure you do anyway. Sent from my iPhone using Tapatalk
