A/C Refill Questions

[Serebros]

Hi/Low Sensor went bad, got another new one, took the old one off, all of the gas came out as expected. But I did not realize that much a/c oil was going to come out.

Car is a 93 KADE S13 COUPE, All Stock A/C Components

1. How much oil do I have to put back in, Can I just run a R134 Can that has oil added all in one?
2. What Kind Oil? PAG? What strength/thickness?
3. Can I fill the oil in from the hole underneath the hi/low sensor
4. Do I absolutely have to pull a vacuum before I refill the system with R134a?
5. Can I get away with not doing the vacuum and just filling it as is with oil?
6. If No, What is the cheapest/easiest way to do it? (Pulling Vacuum)

Thanks

Easies and probably cheapest way would to bring it to an ac shop and get them to convert it...it cost me like $70 when I got mine done

You get kit one of those kits, the problem is that you wont be able to fill it up as much since you have alot of air in the system. It wont get as cold as it should be.
