give me a guess on OCI. 2.0l SAAB turbo. 4.2 quart sump. Half M1 0w-40 half M1 15w-50. Pure One filter. I'm loving the oil already. Really smooth idle. What's a good OCI?
How long?

Since you've got a home brew, it's harder to tell. What's the mfr's first choice for vis grade and OCI? I'd say just pull a sample around 5k miles, see what it says, and decide from there.
It's supposed to be 10-30 with 7,500 mile intervals. I'm not going much past that because it's a hard driven turbo. With 122kmi on the car I think it can take the higher viscosity, and it seems to like it a lot.
