Just checked the GM Dexos 1 site - Supertech 5W20 and 5W30 are now Dexos 1 approved .
At like $17.46 for a 5 qrt. jug at WM - what's not to like ? ... Even if it JUST meets the Dexos 1 spec. , it still has to be an improved formulation over SN and GF5 I would believe ...Your thoughts ?
* Nothing on the jugs that indicates any specs met - except SN , GF5 and API starburst seal ...Not sure if older jugs on the shelf OR Supertech just doesn't list the specs it meets on the jug except the bare minimum requirements (stated above) .
