I need to add just a little bit of refrigerant without doing the whole conversion to 134. Has anyone used this stuff? Is there something better to add to my R-12 system?

I can purge and flush the system if i have to, but would rather not.

r-12 u can find it

but don't want to pay for it

Haven't priced R12 in a while, but it may be cheaper to get the R134a conversion kit.

Your 93 runs on R12?
My 94 runs on R134, it changed in my year?

yes.

And i have everything I need to convert to 134a. My question is do i really need to go through the trouble if i can safely add a can of r12 substitute.

My 93 was OEM R-12 but it was changed 11 months before, thank god...

my R-12 is starting to get warmer. I dont know if I want to pay for a conversion either...

My dad can get R-12. It costs $3500 for a 55gal drum. Wholesale.

I've got a little saved up from pumpimg down some cars in the junkyard to do mine when I find the leak, But getting that was hard even.

50 lb for R-12
20lb for R-134a
conversion kit runs you about 50$ with freon included
