The specification is, non-phosphate ethylene glycol. The late GM
specification meets this criteria. Sierra does not as it is not ethylene
glycol.

Most/all the major companies market the GM spec fluid as
"100,000mile/5year", "extended life", ect. Typically orange tint. Read on
the back the ingredients. Must be ethylene glycol base with no phosphates
listed. Amazing how it took US manufacturers 40 years to catch up to the
higher specs of all the Euro manufactures. They started putting alloy heads
on cast iron blocks in the 50's, which required the higher standard fluid.
