Subzero Refrigerant VS Supertech R-134a For Your Car A/C

In this video, I compare name brand car a/c refrigerant versus super tech walmart r-134a. Does it make a difference which you use in your cars ac system? I've used both and I can tell you if it's worth it to save a lot by getting the walmart brand that may also be more convenient. I explain subzero ac recharge vs supertech, and also talk about stop leak if your car is currently leaking and the air is not cooling.
