I had a look at that the other day at a local Walmart. Personally, I don't think it's worth paying $50 for a 5-quart jug to go 20,000 miles, whereas you can get the EP 15,000 mile version for about $28 and change. I would also have to say that most any synthetic oil would be good for a year, providing that you do not exceed the appropriate OCI for the version that you are using.
