motor oil
The 1990 Chevrolet S 10 pickup truck 4.3 liter air-conditioner compressor can hold five pounds of Freon. Most Freon recharge kits will tell you when the Freon is full. If the system was void of any oil it would probably take 8 to 10 ounces of oil for proper lubrication. If you are only replacing the compressor, add three ounces to the suction port and be sure to turn the compressor by hand several turns clockwise after installation to disperse the oil through the pump. The refrigerant it takes to fill that system is more like 30 to 36 ounces not 5 pounds.
does cooling system hold pressure?
Why would you want to even consider doing this? R12 is no longer in production and as such it cost almost 4 times as much as R134. But to answer your question, use R12 in a R134 system and you will destroy the compressor as the oil is not compatible with R134 oil.
The newer Freon (r134) does not mix with the old Freon. The system needs to be flushed, special oil added so that r134 will be compatible with the system gaskets, then a vacuum pulled. Then the Freon can be added.
You do not want to buy Freon as it is very, very, expensive. Have the leak repaired, the system purged of all Freon R12 and the oil. Have it converted over to R134 refrigerant. You cannot just add R134 as the oil used in R12 is not compatible with R134. You will be money ahead by converting it.

Don't. R12 is so very expensive that you should have your vehicle converted over to use R134. You have a leak or you would be needing to add refrigerant. Have the leak repaired by a professional and have the system converted over to R134. The will remove all R12 & the oil from the system and replace it with R134 & the correct oil. They should pay you for the R12 due to how valuable it is. You may end up spending very little on this repair.
