Hence the nickname Buzz Flash. Many hate it, I happen to like it, but it does have some weird traits and being cold-blooded is one of them. You can pretty much forget running 15W40 under 40 degrees with the Buzz Flash.
My old 2005 also had that flash. Served me well for 150,000+ of the 170,000+ miles I put on that truck. Just couldn't use 15W40 from October to March
