Is there a bible of Oil/Refrigerant quantities for cars, that is available for European models?
Oil/Dye injector units. Do I understand things correctly when I say that they are a vessel with a screw top lid, you fill them up with the required amount of Oil, the oil is squirted into the evacuated system (via the incorporated valve), when putting new refridgerant into the system? If so, is there not a small amount of air left in the top of the oil vessel, which also goes into the system, or is it of no significance?
Sorry for so many questions, really would appreciate positive help in this matter.
