Are the pressure and volume charts absolutely correct?
No, just like any other refrigerant, the pressure and volume charts should be used as a GUIDE. We have found that you can have three of the same cars, same age, and they will all take different amounts of refrigerant, not significant differences, but different in volume. The key is to use the chart as a guide rather than the rule. Often systems have component changes such as longer or shorter hoses – these types of changes may affect the volume which will affectthe stated or recommended charge.
