Recently acquired 2 new Civic hybrids, it will take a while before the first OCI, but im ready with 2 gallon jugs of Amsoil Signature 0w20 and a spare quart (apparently change is 4.2 quarts with filter) i have also accumulated 4 of the newer Mobil1 M110a filters so I'm good for a while. Apparently Amsoil will be making some adjustments to the Signature formula this summer and they have a new supplier for the EA filters (formally Champion) that will be available this fall, so holding off to see what they come up with.
