I'm not sure what I'm going to do regarding this subject (07 Classic D/A). GM says it's not necessary and the gov says a lubricant is added to the ULSD to replace the sulfur (a lubricant) removed from the LSD. Naturally, the local Stanadyne dealer says it's absolutely required, he even gave me a pint. Maybe next time out, I'll run a tank with and a tank without and compare the results. At least the Stanadyne is GM approved.
