I have an 08 Civic 5-spd as well. I like SSO a lot in that car, especially when I get on it a bit.
I might start changing the oil & filter every B maintenance once I'm out of the warranty period. I don't see much problem using SSO and a premium oil filter every 12,000 to 15,000 miles. If I want to push it longer, I'd probably invest in a UOA at 15,000 miles to see how the oil's holding up.
