I’ve used the natural gas replacement for R134a from Envirosafe. I got it to work good in a few systems that have a condenser fan that runs full blast all the time. I’ve never been able to get it to work as good as standard refrigerant in vehicles. The cooling seems to go up and down while you are driving. You also never know how much to put in. The conversion charts never seem to be accurate.
