Not as sweet as the first, with that sale I didn't even know about (@$3.99). I bought 5 quarts. 4 are M0507 and one is M0428. The M04 I think matches the one leftover quart of GC that I have from months ago. It is green. The others don't seem to be (as I expected). I'll probably end up mixing batches at some point, but not sure when. At my next OCI I will be trying T&SUV so the GC will sit for a while. Just put M1 0W-40 in the Camaro, too. I think I'll put the GC in the Camaro next time. Startup noise seems to be louder the last few times I drove it, which looks to be standard issue for 0W-40. On the shelf I saw 3 yellow USA M01 quarts. Also saw two M05s that appeared to have been opened. Is someone sniffing around the Middletown, RI Autozone?? I asked the guy at the counter if he knew about GC and he seemed surprised someone would be opening containers to sniff the oil. This was right after one of the other guys who works in there asked me about my Caprice for the 18th time. He and another guy seem to like it...one time this guy made me give him my number so he could call and make an offer. I wasn't even selling but he never called. People are weird.
