Anybody have an idea what's going on or what we should use in future. I did read somewhere that 5w/30 Dexos is a replacement for street use. I wonder if this is in some way related to oil pump failures.

No problems with that number in the states. 19370233 Does not supersede to anything else and is still a valid and current # in GM's system.
