That depends. If the Delvac 1300 meets the what the manual calls for with respect to API and viscosity, sure. I use Delvac 1300 in my Audi in the summer, since it only calls for an API spec (no ILSAC or APEA) and since Delvac 1300 is SM it exceeds the engine's requirements, and 15w-40 is the preferred summer grade. Other than an HDEO, there aren't a lot of 15w-40 oils out there.
If your vehicle requires, say, an SM/GF-4 or better and a 5w-30 grade, well, Delvac 1300 isn't going to meet your requirements, and may be an issue under warranty. After warranty, it's up to you, and certainly depends upon the vehicle.
As for mileage, that's a shot in the dark. It depends upon how it's driven and what kind of a vehicle it is, which we don't know.
