This Mobil 1 data sheet for 10w30 sold in Australia states it is the factory fill for the "Holden Special Vehicle (HSV) V8." Any of you guys from down under know what this engine is? I suspect it's your version of the all aluminum LS1, which comes with Mobil 1 5w30 in North America.
Also, the product number for this 10w30 is the same as the 10w30 on the North American data sheet.
