A/C - a guide for upgrading R134A systems to R152A

Robin, it also sounded like a dad joke like a velcro: I don’t like velcro. It’s a ripoff.

My 1990 XJ6 was dealer converted to R134 about 13 years ago and a compressor was changed about 5 years ago. (leaking). Using R134 It is not a powerful AC system so I am wondering if a second conversion to the new R152a is likely to improve the cooling performance?

I use hot shot with great results and no mods.
