Well, I called and they do sell it now. My cars are older, and the savings I would see is not having to crawl under my car as often. My only concern is that my oldest car just began using HM oil. I researched Amsoil and found that they have the same seal conditioners in theirs as do the HM oils available at Wal-Mart and all other supply stores. And since my vehicles fall under severe service, I could go 15k or 6 months. Just sort of scares me to know that my oil will be black as night after 4 months, so I need to be 100% sure I could go 6 months otherwise I’d be wasting my money.
