My 92 300E has R12. I believe when the law passed it took effect the 93 model year, even though some companies began sooner. Mother's 92 Volvo has R12, but a friend's 93 Volvo has R134. My 300E has a very slight leak I believe, but after a charge is working beautifully. Plan to have it repaired over the winter, and will probably convert over then due to the fact it's around $60 a lb here in Dallas. Found it for $35 a lb in Arkansas, but not worth the drive really.
