My AC compressor recently seized up on my 1997 F350 7.3L Diesel after 90,000 miles. It's a heck of a job replacing all the components and flushing the system to restore operation. I'd rather it not happen again. In disassembling my old FS10 compressor, I found no wear at all. Just a simple seizure from no lubrication from the PAG oil/R134A refrigerant. Do these newer CFC free AC systems need more maintenence, such as adding oil ect? I don't mind paying a couple hundred bucks every couple years to maintain the system if that's what it takes. Anybody in the business have any insight on this? Thanks, Ron Hansen
