Hey all,
I bought a 2004 Impreza with a 2.5L N/A engine and 107Kmi. I started off with Auto-RX an Castrol GTX 10w-30. I'm coming to the end of the 'rinse cycle'. I am thinking of using GC 0w-30, Mobil Delvac 5w-40, Amsoil 0w-30/5w-30/10w-30/15w-40. I am wondering what oil has the best results in this motor? I also own a 2001 Jeep Cherokee, 1993 Dodge Cummins, 1982 Kubota 305DT, and 2006 Kubota RTV so 5w-40/15w-40 is already a given. Will I take a fuel economy hit with syn xw-40 in the Subie?
Regards,
Brian
