API SE or SG oil is obsolete, but no API SP oil is obsolete.
The question that remains is if the 10W30 viscosity grade is suitable for your application. A 30 grade has enough HTHS for most routine applications, and a 10Wx oil will start down to 0F (-20C). This will do me.
I recently purchased a few 5L jugs of semi-synthetic 10W30 rated API SP & ILSAC GF-6A. The price was good and they will definitely be used in my car.
