Is this the same as SP-20?

It is not the same, however, PAG 46 is also for R134a systems

If I use this in my auto a/c, do I have to also buy a refrigerant with (additional) dye to test for leaks? or is this a one and done for the dye?

This has the dye included. But to check for leaks you still need the light and glasses or you can take to a shop who has these

Can this product soluble in 3M FC72?

Hello, is for R134a A/C systems
