TODAY is a Great Day to visit our Store and order the parts you need for your truck!
Somebody school me, but I thought you were suppose to use Esther Oil on a R12 to R134a conversion and not PAG oil. If you use PAG oil, which is what OEMs use, you have to be sure to drain all of the old mineral oil out of your system by taking the components off and manually draining them. PAG oil does not mix with mineral oil.
