'89 Town Car oil

rhb1999 on Wed May 11, 2011 3:19 PM User is offline

Year: 1989
Make: Lincoln
Model: Town Car
Engine Size: 302
Refrigerant Type: r-134a
Country of Origin: United States

Hello, I'm kinda new here. Sorry, but I have to ask a stupid question. Does anyone happen to know how many ounces of oil (pag 46?) should be in an retrofitted sytem, on a '89 Lincoln Town Car? I believe the r-12 charge is 3 lbs 2ozs., plus the amount of for the oil?, also what are the high and low side readings for this car. Thanks in advance.

My personal preference is BVA Auto 100 ester oil for retrofits.. If using Pag, then 46 is the the one.. Use 8 ounces on a flushed empty system.. Pressures will fluctuate with outside temps and humidly. Post your pressures along with the outside temp and humidly and we'll check it out.. As I said, the BVA is my choice, and never had a problem with it....But it's your choice... Hope this helps...

Thanks, TRB. Is there any real difference between the 10pa17 and the 10pa17a?
