AC compressor oil for Sanden 508 running R134a

What is the best compressor oil for Sanden 508 compressor? I will be running R134a refrigerant. I heard to use PAG46 can anybody confirm this is correct please?

If you use any good R134A Pag oil you will be fine.

SEE: How I converted my a/c to r134a | Volkswagen Owners Club Forum

If you are changing your receiver dryer, and or compressor, then drain the oil out and measure it, then refill the compressor with oil, and spin the compressor by the 13mm bolt on the clutch, and fill until the oil is in the same amount that you drained out.

Briano1234, yeah system is new apart from the hoses and condenser. Brand New evaporator, compressor and drier. Thanks for info, Will check out your thread!

Also just for info I got thru to the 4seasons folks on the phone and they advised that PAG100 for the 58113 / Sanden 508 compressor.

See the thread I posted, then use the amount that is needed and place half in the receiver drier, and half in the compressor prior to either drawing vacuum or adding R134A.  Also if you look there are R12 replacements that don't require a License to purchase, or use the more expensive r134a as they are a mix of 134a and either butane or propane is COLDER.

Also as 134 has less volume you don't use the r12 amounts in the thread you will see the Ratio of formula for the poundage conversion.

Also when you start out using the a/c on a hot day crack your windows and place it on max a/c and full cold.  It will re-cycle the cabin air and gets colder quicker.
