TSI SupercoolA/C Comp Ester Lube, 8 Oz, Yellow (E8)

I didn't read the description very clear. That's my fault. I've been using this for years. I use this instead of PAG Oil. I like the fact that the dye is already in the oil. A+

Easy to use

Works just like the non die oil. I'm not sure why it was double the price just because it has die in it, but other than I guess it's fine.

when you change you AC system in you car from freon R12 to A134 I suggest use easter oil

Ester oil with dye as described. I used this when converting from R12 to R134 so it wouldn't gell with any remaining mineral oil like PAG oil would.

worked as advertised

Bottle came with cap missing only safety seal

Even though I cleaned out my old system piece by piece you'll never get all of the old R12 residue out so I needed this Ester oil to be compatible with converting my system to R134a. Works great, PAG oil would have attached and gummed to the R12 but the Ester oil doesn't react with and works with R12. Compressor runs smooth, just topped up a few drops for the new dryer and now since it's UV dyed I can check my system for leaks in the future. So far I'm running smooth without issue, great product for any old system conversion.
