A/C oil replacement

[MR.K]

I have a 08 and I need to recharge the A/C but also have to add new oil in it ...The car was a builder ....what oil do I use and where do I get it or is it a dealer item only...thanks m

The service manual (2007) says to use ND-OIL 11, Do not use any other oil type because of the possibility of electric leakage in the compressor.

How much oil do you put in??? ie 3 oz

[dogfriend]

I found the specs for the compressor and the condensor, but I don't know if that is equal to all of the oil in the system. Here are the pages that give the oil quantity:

i was reading this today too, apparently depending on which model you got (192 or 193 i think) your suppose to drain the oil and then put as much as you drain in. The amounts were very small (50 cc to 90 cc but don't take my word for it) as they highly recommend putting as much as you drain and not to assume.

Yes, I bought a CD from Ebay (probably not legal) that has the 2007 Service Manual. I also downloaded other manuals (body repair, elect harness repair) from techinfo.toyota.com(TIS). You have to subscribe to TIS; for 24 hrs, 1 week or 1 year. I believe there is an equivalent based in the UK for European cars.

One more thing. Apparently there is some special insulating quality about this ND-OIL 11 that if you even get a small amount of regular A/C system oil in your car, you have to change out pretty much the whole system. Here's the sneak path for oil contaminants: If you use a gauge set that was used on another vehicle, you can accidentally introduce a contaminant oil into your system. YOU SHOULD HAVE A DEDICATED A/C GAUGE SET FOR YOUR PRIUS.

Yes, I know. I never would have thought about it myself had I not been reading this thread and (just for the fun of it) looked up to see if the ND-OIL 11 is available aftermarket - then I happened to read this on another web page. It makes sense.

On the bright side, if you've never put oil in any of your other car A/C systems and only used straight R-134 (without the leak detection stuff in it), you're probably OK. In any case, all you can do is wait and see. Normally, you should not have to add oil to your system unless you've changed a compressor/evaporator/condenser etc. or had a serious leak.
