So I went back to my "country" hometown to visit family. They just got their only AZ about 2 years ago. I couldn't resist- I'd just check and leave. They had 9qts of G04 and 6qts of (G01!). I bought the G04. The guy even said he had lots of it, he even let me go in the back store room- only other grades. However, he said he knows of other stores that have significant quantities. So I get home and add the 9 to the stockplile- giving me 118 GC and 11?(BC). BTW I have been using the BC this OCI and I'm very impressed subjectively- I'm even running GT104 race fuel right now and the engine is still quiet! And fast.
