So comming up on my 2nd oil change. First was factory fill drained at 1000miles. Then the dealer gave me the first change which of course is Subaru Syn 5w-30. This will be drained at the 3000 mile mark. I ordered OEM Subaru filters and went to Wallyworld and found Castrol 0w-40 Euro formula. I heard this would shear to 30wt standards after a few thousand miles. I have searched for UOAs with this oil but found the 0w-30 UOAs. I plan on doing 3000 mile oil changes till about 9k miles. Then doing oil tests to see if it can go to 4-5k, which would be a once a year OCI. This is a garage car, only driven for fun and occasional trip to work.
Any flaws in this plan.
I chose the 0w-40 because its $22 and readily available. The other plan was Motul but cant seem to find it on any shelf around me.
Car is stock and will remain stock. I like all my parts#s to match the factory service manuals.
