Can Mobil 1 synthetic be used in place of esther oil ? I am working on an MC 9, factory system, that was converted to 134 about 10 years ago and am recharging, purging, cleaning, flushing. It has worked great and I wouldn't trade for anything.
Hi BC Bus,
No... Because it is a very different viscosity then M1.
The poly Ester oil is designed to mix and atomize with R-134A as well as lubricate the compressor.
Go to your local Appliance parts house and spend the $65 on the poly ester. It will save you lots of headaches.
Good Luck

Thanks Nick for the info. Do you know what the capacity is for the 3 cyl compressor ?
About 1/2 gallon
