An extended OCI is what you're getting, and a superior oil for protection in extreme circumstances. That being said, dino is fine in many applications - I used it in my old Bonneville until I switched to MaxLife semi-syn. $10 is a significant difference, but it's really only 3 gallons of gas - how far to you go on that? Napa Syn on sale for $3.49/Qt makes the decision a bit easier. Dino is great and cheap if it suits your needs, but claims of superior mileage are a bit much IMO.
