Wilton, First, I think you are doing the wise thing by sticking with R-12... I'm a strong proponent of fixig & recharging R-12 systems, and NEVER converting to R-134a (or anything else that won't work with mineral oil.)
Anyway, what I would recommend is getting your EPA certification online, cost is under $20. Then buy a few cans of R-12 off eBay, or wherever else you can find it cheap. Pretty sure 12oz cans are still selling for ~$20/ea on eBay. I think it will take a bit over 3 cans to fully charge an empty W124 system. Maybe 3 cans would be enough to give you 90%+ charge so you don't need to tap into a fourth, lol. You can find 30lb tanks for $400-$500, but there's always a risk that it's not virgin R-12. I'd be really careful buying one of these unless it's a local seller where you can personally inspect the tank before buying, to make sure the factory seal is intact. Worst case, convert to an alternative refrigerant that works with mineral oil, like AutoFrost. The drawback to these is you can't top off... not a big deal if your system is leak free. :-) -Dave M. > ------------------------------ > Date: Sat, 4 Mar 2006 11:34:37 -0500 > From: "wilton strickland" <[EMAIL PROTECTED]> > Subject: [MBZ] R-12 Freon > > > Otherwise showroom 87 300D (124) needs Freon.
