I have a 2003 Honda Accord and a 2006 Acura TL. Both cars specify a 5W-20 oil. I have been running the Series 2000 0W-30 oil in the 2003 Accord since new. The 2006 Acura is going to need an oil change and I was planning on using the 0W-20 oil. However; with this new Signature 0W-30 oil, should I use this? Cars are always garage kept, see under 10k year, no really harsh weather, and I change the oil at the 1yr mark. I use the Amsoil oil filters, too. I am more interested in fuel economy and I don't mind paying more for the Signature 0W-30 oil if it is that much better. Thanks.
