What brand/application type dye kit does one recommend for R12 sytem with mineral oil? I have seen the autozone stuff and it says for R134A/pag oil, where to purchase?
Thanks

Sniffers detection ability can be hampered by air movement for obvious reasons - especially when looking for small leaks. Internal components they work fine, I do not like them for engine bay work with a running engine.
The best UV kits have the yellow glasses.
R12 oil is usually a viscosity of 500....and worth mentioning here there is not a universal PAG for R134 as it's available in 3 viscosity's (ISO 46, 100, 150). I feel it's important to look at the compressor mfg. suggested PAG type.
