do you know what oil type can i found in the shops? i went to gm shop and they not sell it.
Expert:  Chris (aka-Moose) replied 5 months ago.

Odd the dealer does not sale PAG oil for AC systems. I bet the parts department at my dealer has 50 bottles of it. You can buy PAG oil at Walmart, and most every parts store.

i just look for any oil with label Pag-46? some brand you recommend? the gm oil is much better than the others found in the shops?
Expert:  Chris (aka-Moose) replied 5 months ago.

That is correct PAG 46 is what is needed. GM does not make PAG oil, they buy it from a supplier and put there name on it.

can you tell me the brand of the oil where gm buy it? or a good brand i can buy?
Expert:  Chris (aka-Moose) replied 5 months ago.

I can not tell you the brand oil GM relables. I am just a dealer tech, that happens way above my pay grade and title at the manufacturing level. Any brand should work just fine. I have never ran into an issue where one was low quality and caused premature failure.
