Mixed PAG and ester in my A/C?
 

I may have accidentally mixed some PAG oil in my A/C system.

It is on a 1984 300D, which was coverted to R134A.

What should I do?

Should I have it evacuated immediately?

HELP!

This used to be viewed as a real no-no, but now it seems to be more acceptable. The fact is you have a converted system so statistically it will only last a couple of years anyway.

I think the total quantity of oil is more important. Too much will load the compressor or possibly destroy it from liquid lock. Too little will wear it out.

Best of luck with it,
